These days, it’s almost impossible to imagine visiting a foreign country without mobile connection. You may need to call a rideshare, find your hotel on maps, connect to the internet when away from Wi-Fi, or translate signs in a foreign language.

However, using international roaming with your home carrier to get data could cost hundreds of dollars. This is why prepaid eSIM cards are the fastest growing option for international tourists who own an eSIM-compatible device.

In this guide, you’ll find the 5 best prepaid SIM and eSIM options available for tourists in Japan in 2024, including their pricing and data plans. Let’s get going!

Airalo is our top choice to avoid expensive international roaming fees. Airalo offers eSIMs tailored to you, from 5 days up to months at a time, covering hundreds of countries, with both multi-country and various GB plans available.

Facts About Prepaid SIMs in Japan

Where to buy physical prepaid sim cards for japan.

In Japan, obtaining a prepaid SIM card is fairly straightforward for tourists, although we recommend you purchase one online beforehand or at the airport upon arrival, where English proficiency is generally higher. Note that tourists won't receive a phone number with their SIM card due to restrictions only allowing residents and citizens to obtain Japanese phone numbers.

1. Japanese Airports

Narita, Haneda, and Kansai airports in Japan offer a broad selection of SIM card options for visitors at designated kiosks.

2. Network Provider Retail Stores in Japan

You can also find data-only tourist prepaid SIMs in electronic stores such as Bic Camera and Yodobashi.

You could also consider having a physical prepaid SIM card shipped to your house before you travel by shopping on online sites (like Amazon). You’ll often find small SIM card providers that partner with the large Japanese networks (like NTT Docomo or KDDI (au)) to connect your phone to mobile data. You could even consider buying a portable Wi-Fi hotspot device.

Shopping online requires a little travel pre-planning but allows you to search around for better prices and data plans that meet your needs.

The easiest online option, and the one that we highly recommend, is to purchase an eSIM. These digital SIMs can be instantly activated straight from your smartphone from apps like Airalo and Holafly , which then give you seamless access to data in your travel destination.

Registration Process For Prepaid SIM Cards in Japan

In Japan, no registration is necessary as long as you buy data-only SIMs, and you don't need to show your passport to the issuer. 

It's worth noting that an increasing number of countries are requiring registration from mobile phone users for security reasons, where purchasing a prepaid SIM card requires consumers to provide proof of identity.

For the countries that have these Know-Your-Customer (KYC) laws, registration will also apply to eSIMs. However, eSIMs do have the benefit of digital registration as opposed to the hassle of an in-person process. If your eSIM is data only (no local phone number), then you may be able to get connected without registering your info.

Cheap Physical Prepaid SIM Card Options For Japan Travel

Here are some of the most popular options for plastic SIM cards for tourists in Japan:

IIJmio (which uses the NTT Docomo network) is known for its reliability and popular options among tourists.

They have SIMs with 1.5GB of data valid for 30 days at approximately €13.49, or 3GB of data also over 30 days for around €20.23.

2. Sakura Mobile

Sakura Mobile is another favorable choice, known for its range of unlimited data packages suitable for short and longer stays.

The first plan offers unlimited data available for 8 days at about €30.35. A 15-day unlimited data plan is priced approximately at €43.84. For those in Japan up to a month, an unlimited data package over 30 days can be purchased for roughly €60.70.

Best Digital Prepaid e-SIMs For Tourists in Japan

Want to ditch physical plastic SIM cards? You can conveniently download and active the following international eSIMs from your smartphone instead.

Airalo is an excellent eSIM provider for international travel. For Japan, they offer eSIMs from 1GB for 7 days at $4.50 up to 20GB for 30 days at $26, and other plans in between. It was super easy for us to set up in the app and purchase instantly.

More info: Read our Airalo review or visit their website .

Holafly offers unlimited data volume packages for international travel. Holafly's data packages for Japan cost between $6 and $139 once off and are valid from 1 to 90 days, offering peace of mind that you'll never run out of data.

Although Holafly offers unlimited data in most countries, including Japan, if you're a globetrotter, it's worth keeping in mind that Holafly offers limited data plans to some other destinations. Be sure to check their website or app before traveling to a new country to confirm whether Holafly's unlimited packages apply.

More info: Read our Holafly review or visit their website .

Yesim, a Swiss-based eSIM service, offers flexible plans for 3GB, 5GB, 10GB, and 20GB. The pricing of these eSIMs for Japan range from $13.20 to $49.50.

The 3GB plan is good for 7 days while the 5GB one is good for 15 days. The 15GB and 30GB plans both last for 30 days.

To make sure your phone can support eSIM cards, read our list of eSIM-compatible phones .

Largest Mobile Network Operators in Japan

eSIMs are great because they connect to the best network available wherever you are. Your phone might connect to NTT Docomo or KDDI (au), depending on your location, at no extra cost. In contrast, if you buy a SIM card directly from one Japanese telecom provider, then your phone will only access that provider's network.

In Japan, expect to see these names as you connect to data on your travels:

• SoftBank: Aggressive investment in next-generation mobile technologies, including widespread 5G deployment.
• KDDI (au): High-quality network performance and comprehensive service packages in both urban and rural areas across Japan.
• NTT Docomo: Offering extensive 5G coverage and the overall widest coverage across Japan.

Frequently Asked Questions About Prepaid SIM Cards For Travel in Japan

Yes, it is wise to plan ahead, but you can also opt for an eSIM even 24 hours before your trip if you have an eSIM-compatible phone. The best part about eSIMs like Airalo and Holafly is that the plans won’t activate until you connect within the plan’s designated country. This means you won’t be on the clock until your trip finally starts.

We believe Airalo offers the best prepaid eSIMs in Japan and around the world in 2024, with options that are 5G compatible, starting from 1GB for 7 days at $4.50 up to 20GB for 30 days at $26.

Check our list to make sure your device is compatible with eSIM technology.

What’s the best tourist SIM card for Japan (2024 guide)

By: Author Kris

Posted on Last updated: January 22, 2024

If you’re headed to Japan and want to stay connected while exploring, we’ve got you covered with the top tourist SIM cards. No need to worry about losing touch with your loved ones or missing out on those Insta-worthy moments.

We’ve spent a lot of time in Japan and traveled all over the country. The first trips we would very often come across a “Handy” phone in our hotel room – a phone we could use throughout our stay. But those days are long gone now.

Nowadays, if you want to stay connected, you better have a local SIM card if you don’t want to rely on public hotspots. And trust me, from experience, we can assure you that a local SIM card is still highly recommended.

There are several spots offering free internet, mainly in the larger cities, and handy apps to connect to WiFi hotspots for free. We share more information on this app in this article. Still, there are still plenty of places that require a data subscription for internet usage.

Whether you prefer the convenience of ordering physical SIMs online and picking them up at the airport or exploring the innovative world of eSIMs, there are numerous ways to ensure you stay connected on your journey.

Japan Tourist SIM cards – The top choices

In this article, we discuss no less than 30 different Japan tourist SIM cards.  All of which have slightly different options.  It’s good to have a choice but with all these different options it is hard to see the forest for the trees.

We discuss all the details of the SIM cards further down in this article but here are our top choices:

For the occasional data user

Most SIM cards offer unlimited data but all providers have implemented a fair usage policy. If you consume more than what is covered by the fair usage policy your data speed will be reduced. Sakura Mobile cannot share the exact details of the fair usage policy, therefor we recommend them for occasional use. Their prices are very competitive but they cannot be used for video streaming or as a hot spot for your laptop.

If you just want to make sure that you can fall back on your data plan if you need it but you already know that you will only have to use it occasionally, these are your best options.

Short stays

At JPY ¥4,000 for 8 days the SIM cards provided by Sakura Mobile are reliable and very cheap. 

The SIM card offers unlimited high-speed data at 4G or 3G speeds.  You will find a very detailed document to check if your mobile is compatible with the local network. Sakura Mobile uses the NTT Docomo network in Japan, generally seen as the best network in the country.

Thanks to the detailed information you can buy this SIM with peace of mind, knowing that it will work once you are there. If you’re still unsure you can pay a supplement for compatibility insurance. With this insurance, you will receive a WiFi device in case the SIM does not work in your phone.

Alternatively, if your phone is incompatible (see our FAQ below) with the NTT Docomo network you can opt for a Mobal SIM that works on both the NTT Docomo and the Softbank network.

Longer stays

If you are 2 of 3 weeks in japan.

For stays of 2 or 3 weeks , you’re in most cases also best off 16 or 21-day cards of Sakura Mobile that can be found on Klook.  At JPY ¥6,000 and JPY ¥6,500 they are the cheapest options that can be found for these durations.

Both SIMs offer unlimited high-speed data at 4G or 3G speeds.  4G is offered in major cities while the 3G is applicable in more rural areas. You will find a very detailed document to check if your mobile is compatible with the local network. Sakura Mobile uses the NTT Docomo network in Japan, generally seen as the best network in the country. It has a coverage of over 99%.

Once you have read through the detailed information you can buy this SIM with peace of mind, knowing that it will work once you are there.

If you’re still unsure you can pay a supplement for compatibility insurance. With this insurance, you will receive a WiFi device in case the SIM does not work in your phone.

Alternatively, if your phone is incompatible with the NTT Docomo network you can opt for a Mobal SIM that works on both the NTT Docomo and the Softbank network.

If you are longer than 24 days in Japan

If you will be in Japan longer than 24 days the 30-day card of Simcard GEEK that costs JPY ¥4,980 is a good buy.  The card comes with 7GB of high-speed data which should be sufficient to cover your needs.  This SIM card also connects to the NTT Docomo network which is generally recognized as Japan’s best network.

Simcard GEEK has a fair usage policy of 3GB/day.

For the heavy data user

If you want to be online the whole day,  enjoy streaming music, or watch YouTube videos, you’re better off with the below SIM cards.  This may also be the case for those who will be sharing your data plan with friends or family members, maybe by means of a mobile WiFi device.

These SIMs also have a fair usage policy. In this case, however, you know the details of the policy and can therefore pay attention to it so that you are not faced with surprises.

Mobal offers SIM cards for 8 or 16 days with an unlimited data plan .  The cards have a fair usage policy which limits high-speed data to 3GB per day. 3GB is quite a lot, it will allow you to browse the internet for 36 hours, stream 600 songs, or watch 6 hours of standard definition video. 

Consuming this amount of data in one day would probably mean that not much time is left to see the many stunning sights Japan has to offer.

Click here for more information and to order your Mobal SIM card: Mobal Tourist SIM

Mobal has a SIM with an unlimited data plan for 31 days.   This card has a fair usage policy which limits high-speed data to 3GB per day. 3GB is a lot, in the previous paragraph we gave a small overview of what exactly you can do before you reach this threshold. 

If you go out and discover the city you will probably never consume that much data in one day and if you stay in your hotel you can use the WiFi provided by the hotel.

One standout feature of Sakura Mobile is its compatibility insurance option.

This provides peace of mind and ensures that you’ll be able to stay connected without any hiccups.

In the unlikely event that you do encounter connectivity issues, Sakura Mobile offers a solution to those who took the insurance option – an upgrade to a Pocket Wi-Fi device at no extra cost. Alternatively, if you prefer, they can also provide a refund.

You have multiple options when it comes to ordering Sakura Mobile SIMs. You can either purchase them through Klook or directly on their corporate website . While the widest range of options is available on their own site, it’s worth noting that Klook offers certain exclusives not found on the corporate website.

On the other hand, when ordering directly, you can choose from more pick-up locations or have the SIM shipped to any address within Japan, including hotels.

Japan SIM cards with pick-up abroad (via Klook)

Here are a few extra options for those who live in Thailand, Malaysia, Hong Kong, Vietnam or India.

The below providers offer SIM cards that are either shipped to your home or that can be collected at your airport of departure.

Personally I would prefer to pick-up my SIM in Japan.  This has the advantage that somebody can assist you with setting it up and in the unlikely event that it doesn’t work, you would be able to look for an alternative or arrange a refund on the spot.

A pick-up abroad might, however, be a convenient option if you don’t want to lose time collecting your SIM upon arrival.

Buying a SIM card in Japan

Don’t worry if you’re already in Japan when you’re reading this. 

It’s also possible to buy a tourist SIM card in BIC Camera and Yodobashi Camera stores as well as at Narita and Haneda airports. 

You can even order one online and pick it up in several locations in downtown Tokyo, Kyoto, Osaka as well as other cities.

At the airport

If you want to start using your SIM card immediately you can buy one at the airport.

In the arrivals hall are sales counters from various operators and they will certainly be able to assist you in English. 

The drawback is that your choice will be more limited than in the shops in the city and you will be paying more, as is always the case at airports.

BIC camera also operates one small store in Narita and 2 in Haneda airport terminal 3 (see here and here ).  The sales points from the operators will likely be able to better assist you and give you advice while the stores from BIC camera will likely be cheaper.

In the cities

Another option to buy a SIM card in Japan would be to head to one of the BIC Camera or Yodobashi Camera stores in the cities. 

They sell various prepaid SIM cards for Japan tourists.  Usually, someone will be able to assist you in English but don’t expect the store personnel to speak the same level of English as they would at the airport. 

If you know what you need they will be able to point you to the correct package or confirm that what you picked is what you think it is. But you better speak some Japanese if you want to go into lengthy discussions about what would be the best option for you.

Finding these stores is easy.  Your hotel should be able to tell you the nearest one or you can use Google Maps.

A visit to a BIC Camera or Yodobashi Camera store is something that we absolutely recommend.  It is a fun experience during which you can marvel at all the electronic gadgets that are for sale.

But maybe you prefer to compare the various options from the comfort of your hotel room.  This is possible as well. 

You can order your SIM online with Mobal and pick it up directly at one of the many pick-up locations across Japan.

They have a very informative website and offer English support in case you have any additional questions.

One SIM works only in Japan, the other works in Japan & South Korea. Both are data only. The data package varies with the duration of the SIM.

Japan SIM card for longer stays

For a short stay, you’re best off with a prepaid SIM card but if you’re staying in Japan for several months you could consider an unlimited long-term plan.  

Japanese providers are known to have a lot of red tape.   

A contract with them usually requires a lot of paperwork and a commitment of 2 years. For some, you even need to have a residence visa and/or a Japanese bank account.

Two providers offer long-term SIM plans :

FAQ About Tourist SIM Cards for Japan

Will your phone work in japan .

Before you buy a SIM you need to be sure that your phone is compatible with Japan’s telecom network. It needs to be able to operate on one of the bands used by the telecom operators in Japan. 

Check the technical specs of your phone to see what bands are supported and see if there’s a match with the bands that the operators are using. We’ve listed all of them in the following section.

Your phone will also need to be unlocked.

If you don’t want to do this manually you can find pages online ( like this page ) where you can select your phone and the network operator to verify if they’re compatible.

Network providers in Japan

Japan has four mobile phone companies that operate their own network.  The three major players are NTT Docomo, Softbank (formerly Vodafone), and Au by KDDI.

A fourth challenger is Rakuten Mobile. Rakuten Mobile used to be a virtual operator but started building out its own network a few years ago. Today it covers about 94% of the population.

All other operators are virtual and use one of the existing networks. The tourist SIM cards we discussed in this article all work on either the Softbank or NTT Docomo network.

The network of NTT Docomo is recognized to be the best in terms of coverage.  Softbank comes in second although they are not far behind. Both these networks cover 99% of Japan (population-based).

These are the bands used by the Japanese operators:

Rakuten Mobile

Pocket WiFi device vs Tourist SIM card

One big perk of using a pocket WiFi device is that you can stay connected without having to mess with your phone.

No need to worry about changing your settings. Just remember to turn off your data connection to avoid those annoying roaming fees. With your SIM card still in the phone, you can stay connected with friends, family, work buddies, and anyone else who has your number just like you’re back at home.

If you want people to be able to contact you anytime, a pocket WiFi device is a great option.

Another advantage of pocket WiFi devices is that they let you connect multiple users at once (usually up to 10!).

Batteries of pocket WiFi devices usually last no more than a day. This is probably the biggest disadvantage. It is one more device that you need to charge on a daily basis.

Interested in Pocket WiFi devices?

See which ones you can rent in Japan . Or if you are going to use this often, you can buy your own device , just like us.

Which size of SIM card do you need

SIM cards have become increasingly smaller over the years. First, we had the standard SIM, then the Micro SIM and nowadays almost all modern phones use a Nano-SIM

Usually, providers use multi-size (3-in-1) SIM cards that are compatible with all phones.  Others only offer 2-in-1 (Micro and Nano) which means they will still be compatible with most current models. 

The technical specs of your phone will show what SIM you need.

In some cases, you will need to specify the requested SIM size with your order.

Free WiFi in Japan

You can easily find free WiFi at many places in Japan. Coffee shops like Starbucks, metro stations in all major cities, and JR train stations offer this convenient service.

Connecting to public WiFi networks was a pain the first time we were in Japan. Not only did we, have to do it over and over again. We also couldn’t get the connection to work for half of the time.

But now there’s a great app called Japan WiFi Auto-Connect that takes care of all the hassle for you. It automatically connects your phone to selected public WiFi hotspots. Only the trusted ones managed by reliable companies or authorities are used by the app for security reasons.

The app worked perfectly for 90% of the time during our last trips. Whenever we walked into a metro station or train station the phone usually connected to the WiFi in a matter of minutes.

The Japan WiFi Auto-Connect app is available for Android and Apple and makes free WiFi much more reliable for foreigners.

Still, I suggest not depending on free WiFi entirely, just like we don’t. As you move away from the big cities, finding reliable Wi-Fi spots becomes harder.

And even in the major cities, I find it super handy to have internet access all the time so I can look up stuff whenever something pops into my head – not just when I stumble upon a hotspot.

It’s a matter of convenience, but SIM cards are so cheap that I think it’s worth it.

Having a Japanese tourist SIM card turned out to be priceless.  With Google Maps we could easily find our way around the cities, we discovered interesting places to eat and we weren’t restricted to touristic restaurants since we could use our mobile phone to translate the menus.

It really helped us to travel deeper and get a better, less touristy experience of Japan.

There’re many different tourist SIM cards so we wrote this post to help you choose the one that suits your needs.  All information is accurate at the time of writing.

We will regularly update this article but if you notice any changes we would appreciate it if you let us know so we can update our post.

Japan Prepaid SIM Cards: A Visitor Guide with Maps for Airports

A guide to help anyone arriving in Japan find the cheapest and most convenient SIM cards. This guide includes locations of shops that sell SIM cards at Tokyo and Osaka airports, and the various options available to visitors staying from 1 week to 3 months in Japan. I used to travel to Japan frequently and can understand how confusing it can be. Hopefully this guide makes it less confusing.

The JAL ABC counters located in Tokyo Narita and Osaka airports are the most convenient options for good value SIM cards when arriving in Japan. JAL ABC sells the TRE SIM card which starts from 2,647 JPY and includes 2GB of data . If arriving at Haneda, Air Bic Camera is likely the best option. SIM cards can also be purchased online for delivery or collection upon arrival in Japan.

Read on for more details about these and other options, including the best SIM cards for visitors staying more than a week, available at Haneda (Tokyo), Narita (Tokyo), and Osaka airports, and options that can be ordered online for delivery or collection.

This guide to Tokyo's airport SIM cards includes:

• Part 1: Which SIM cards for Short and Long-stay Visitors
• Part 2: Maps to SIM card shops at Tokyo Narita and Haneda, and Osaka airports
• Part 3: Options for ordering a Japanese SIM Card Online
• Part 4: How it can be possible to save money by roaming to Japan (with examples from the US, Canada, UK, Australia and more)

Part 1: Which SIM cards are best for short and long-stay visitors

This part of the guide compares the best SIM cards for visitors staying in Japan up to a week, up to a month, up to 3 months, and more than 3 months. In general, finding the JAL ABC counter at the airport is a good way of finding the best SIM cards available.

For visitors staying a week :

• At Tokyo Narita airport (NRT), look for the JAL ABC counter which sells TRE SIM for 2,647 JPY with 2GB of data 1
• At Tokyo Haneda airport (HND), look for the Air Bic Camera shop which sells b-mobile for 1,980 JPY with 5GB of data 2
• At Osaka Kansai airport (KIX), look for the JAL ABC counter and its TRE SIM for 2,647 JPY with 2GB of data

For visitors staying up to a month :

• At Narita airport, JAL ABC sells the TRE SIM which is valid for 30 days and includes 2GB for 2,647 JPY or 6GB for 4,582 JPY
• At Haneda airport, Air Bic Camera sells b-mobile for 2,970 JPY with 7GB of data and 21 day validity, or Japan Travel SIM for 2,460 JPY with 1GB of data
• At Osaka airport (Kansai), JAL ABC also sells the TRE SIM with 30 day validity and starting from 2,647 JPY.

For visitors staying up to 3 months :

• At Narita , JAL ABC sells a Japan Prepaid SIM valid for 3 months with 2GB of data for 4,100 JPY +tax (data can be added) 3
• At Haneda , there is a vending machine that sells Keikyu Travel SIM with 2GB for 4,200 JPY and 3 month validity (data can also be added) 4
• At Osaka , Softbank sells a 10GB SIM card with 90 day validity for 7,150 JPY. 5

Extending the validity is not possible for the majority of Japan visitor prepaid SIM cards. It is possible to add more data to some SIM cards, this does not necessarily extend the validity.

For visitors staying more than 3 months :

• Smash Mobile (online order) offers plans for short-term residents, Japanese ID may be required for the longer-term options 6 ;
• Mobal offers (also online order) offers an unlimited plan for 4,500 JPY per month with a SIM card and delivery fee charged upfront 7 .

Other good options for visitors arriving in Japan via Tokyo or Osaka airports include:

• JAL ABC’s Unari-kun, which includes unlimited data starting at 4,073 JPY for 7 days 8 ;
• So-net, sold at J WiFi, which starts from roughly 3,700 JPY for 1.2GB 9 .

I haven’t found any benefit to leaving the airport and buying a SIM card in the city - the airport deals are hard to beat in my opinion.

To save money , it can be cheaper to order online for collection at major airports in Japan, such as Tokyo and Osaka. SIM cards that can be ordered online include:

• Klook, which is roughly 1,600 JPY for 3GB of data with 8 day validity. Pick-up is from the Easy-go counter, with instructions provided on purchase (or click here to skip to my part of the guide about collecting an online-ordered SIM card);
• Mobal, with unlimited data starting from 3,990 JPY for 8 days;
• Smash Mobile, which delivers SIM cards for collection from airport post offices (typically open 7 days though close at 8pm) with prices starting from 2,500 JPY (+tax) for 1GB of data. SIM cards can also be delivered to a hotel or other accommodation.

If arriving at Haneda, I don’t like using Smash Mobile: The collection point is in the domestic terminal, which means catching the bus from international arrivals.

I’ve included more information about ordering online here: Part 3: Ordering Online .

Roaming to Japan can also be a good option for people coming from Australia, Singapore, Hong Kong, and New Zealand. I couldn’t find any deals better than roaming for people coming from the UK or Canada. For those from the US, check out AT&T’s Roaming Passport if interested in roaming in Japan.

For more roaming details , I’ve included a section of this guide detailing the costs involved for people from various countries (UK, US, Canada, Australia and more) here: Part 4: Roaming .

If arriving in another city, I’ve written guides on where to buy SIM cards for Nagoya and Sapporo . Click on these cities to check out the details on where to find SIM cards there.

If transiting in Tokyo to a domestic flight , it is possible to purchase a SIM card after passing through customs. The JAL ABC counters mentioned in this guide are close to the domestic transfer desks. Scroll down to see maps below, or click here

Coverage : Most SIM cards, and roaming, use the NTT Docomo network. My understanding is it’s the most compatible with foreign mobile phones. Coverage is great whenever I’ve used it (around major cities, Niseko, and the Tochigi countryside). The alternative network is by Softbank, which Anyfone uses as well. I’ve never tried this one, but I imagine it too has good coverage. Other networks are available but they may not work with non-Japanese phones (such as KDDI).

Phone calls are NOT typically included in Japanese prepaid SIM cards that can be sold to foreigners. See below to find out how I make phone calls when I'm in Japan (or click here ).

Part 2: Maps to SIM card locations when arriving in Japan

This part of the guide includes maps for SIM card shop locations at Tokyo Narita, Tokyo Haneda, and Osaka Kansai airports. I drew the maps myself after finding it difficult to rely on the airport maps (not all the shops were included).

Tokyo Narita & Tokyo Haneda

7 Best SIM Cards for Japan in 2024

Home | Travel | Asia | 7 Best SIM Cards for Japan in 2024

When traveling abroad, get a policy from one of the  best travel insurance companies . Y ou can get a  5% discount   on Heymondo , the only insurance that pays medical bills upfront for you, HERE!

If you want to have mobile data during your trip, consider getting a SIM card for Japan . There are several cards to choose from depending on the purpose of your trip, so I’ll share my top recommendations as well as their pros and cons.

I’ll tell you upfront that we use the Holafly eSIM card whenever we travel abroad, and the company even has eSIMs for Japan . We’ve never had a problem using Holafly, and what I like most about these digital cards is that they’re super easy to install and activate. Plus, the plans come with unlimited data for Japan , so we never have to worry about how much we’re using. You can even get a discount on Holafly for being a Capture the Atlas reader; just use our link.

5% OFF your international eSIM card

That said, if you prefer a physical SIM card for Japan or your phone isn’t compatible with eSIM technology , you can still get internet for travel . In this case, I recommend the Japanese SIM cards from SimOptions , which you can order online and have delivered to your home. Just be sure to order it in advance so you can install it before leaving for your trip.

There are other SIM card plans for Japan , so in this guide, I’ll share the best ones, where to buy them, and some tips for finding the most suitable options for your trip.

How do Japanese SIM cards work?

First of all, you should be aware that it’s against the law for tourists to have a phone number from Japan . In other words, you can’t get a SIM card in Japan that includes phone calls.

Fortunately, you can still get travel Internet in Japan thanks to Japanese data SIM cards that allow you to access the Web. In this way, you can make calls and send messages through a mobile app like Messenger, WhatsApp, or Skype.

When you’re choosing a travel SIM for Japan , always check your device’s compatibility and mobile network first. You don’t want to spend money on a card only to find out once you’re in Japan that you can’t use it with your phone.

If you decide to go with the Holafly eSIM for Japan , I recommend checking your device’s compatibility here . For local Japanese SIM cards , you can check this on the retailer’s website or at the storefront.

Japanese SIM card price comparison

I’m going to share the best SIM cards for Japan , but first, here is a brief overview of my top picks. This way, you can quickly compare the most important stats like price, duration, and amount of data.

You’ll see that Holafly offers the best deal for both short-term and long-term trips. Not only is Holafly affordable, but its cards come with unlimited data, so you can enjoy the Internet without worrying about your data usage. The digital SIM card is delivered via email, so you can purchase it before your trip or when you’re already in Japan.

Of course, I know that some people prefer a physical card, so I’ve included several Japanese SIM cards that you can insert directly into your device. The cheapest option is the Rakuten Mobile SIM, which you can buy from a local store in Japan. The downside of getting this card is that you’ll have to locate a store that sells Rakuten Mobile, and the live customer support is in Japanese, so if you have any issues, it could be hard to find a solution.

Personally, I prefer paying a little more for the eSIM from Holafly since the company offers live chat in English. When I need a physical SIM card, I go with SimOptions because I can order it before my trip, install it, and fix any issues I may have prior to landing in Japan.

What is the best SIM card for Japan?

For us, the best SIM card for traveling to Japan is the Holafly eSIM . It arrives by email as soon as we purchase it, so we can buy it whenever we want, plus it offers high-speed unlimited data.

I’ll tell you more about Holafly as well as the other top SIM cards for Japan below so you can make the best choice for your trip and preferences.

1. Holafly eSIM, the best SIM card for Japan with unlimited data

The Holafly eSIM for Japan is a digital SIM, so after you order your card , you’ll get an email with a QR code that you can scan to start accessing the Internet. This is ideal if your phone doesn’t have a dual card slot, or you are already abroad and need a SIM card.

Keep in mind that to scan the QR code, you’ll need to print it out or send it to your travel companion so you can scan it off their device. Also, I recommend checking your phone’s compatibility here before purchasing the international eSIM .

Looking at the Japanese eSIM card plans for Holafly, you’ll notice that each one includes unlimited data. The shorter-term plans are a bit more expensive compared to other local cards, but Holafly is more convenient, and you can snag a discount on your Holafly purchase by using our link.

2. SimOptions, another one of the best SIM cards for Japan

Another one of the best data SIM cards for Japan is the physical one from SimOptions . I like using SimOptions because I can order the SIM card ahead of time and sort out any issues before my trip. It takes 1-3 business days for the card to arrive at your home, so make sure you order it in advance.

Something else I like about using SimOptions is that I don’t have to waste time and go searching for a local SIM card in Japan once I land. Instead, I can connect to the Internet right away and enjoy the rest of my trip. Also, if your device has a dual SIM card slot, you can simply insert the Japanese SIM card without having to remove your regular card.

SimOptions offers customer support by email and live chat in English, and there are different plans to choose from depending on the length of your trip. The plans have varying amounts of data, so here is a breakdown of the prices:

3. SoftBank SIM, another Japanese SIM card with data

The Japanese SIM card from Softbank is a physical SIM from one of the largest and most prominent communications companies in the country. It’s super popular, so you’ll be able to find it at official retailers, shopping malls, and even supermarkets.

Softbank has 400,000 Wi-Fi points throughout Japan, so you can access the network during your trip for free. Keep in mind that, if you use up the first megabyte of your plan, you can only recharge the card for 14 days afterward. I don’t really see the point of this, but it’s something to consider if you’re using data to work remotely.

Another disadvantage of this card is that you only get 500 MB for 31 days. This is equivalent to about two or three days of navigation, so it’s not a lot of mobile data.

Even so, this is a common prepaid SIM card for Japan , so if you decide to get it, you can purchase it online. You’ll have to register on the website by uploading a photo of your passport and providing some basic personal information.

4. IIJmio, an alternative SIM card for Japan

IIJmio is another option to consider if you’re looking for a local Japanese SIM card . It offers basic mobile data plans for 30 days, and while you’ll only get a few gigabytes, it should be enough for occasional Internet use and Google Maps.

One drawback of this card is that once the data is used up, you can’t recharge it. Rather, you’ll have to buy another prepaid Japanese SIM card . On the other hand, IIJmio offers customer support in Japanese and English, and you’ll receive an origami set with instructions as a gift with your purchase.

5. B-mobile, a popular Japanese SIM card for tourists

If you want to buy a Japanese SIM card online , check out B-mobile . With this service, you can order a SIM online, then pick it up once you land at the airport in Japan. B-mobile can even deliver the card to your hotel.

Regarding its mobile data and network, B-mobile has great coverage throughout the country, so it’s quite convenient for traveling tourists. Also, if you need to extend the duration of your plan or add more data, you can do so without having to buy another SIM card.

Overall, this is a flexible option, although you should keep in mind that B-mobile’s SIM card plans for Japan last from 10 to 20 days and don’t offer unlimited data. So, I only recommend B-mobile if you’re traveling short-term and don’t need too much mobile data.

6. Rakuten Mobile, a good Japanese SIM card for travel

Rakuten Mobile is another company with local SIM cards in Japan . Its 30-day plans offer basic, moderate, and unlimited data consumption, so you should find an option that suits you.

In fact, if you plan on spending a month in Japan, Rakuten Mobile is the cheapest Japanese SIM card , particularly for unlimited data. However, the Internet speed isn’t super strong, so that’s something to consider.

You can buy this SIM card in Japanese shopping malls, as well as in many stores and the airport. Activating it is simple since you just have to insert the SIM into your device to connect to the Internet. Your purchase also includes a free Rakuten Mobile email domain (@rakumail.jp).

7. Sakura Mobile, another SIM card in Japan with unlimited data

The last Japanese SIM card that I recommend is the Sakura Mobile card. This local SIM offers some of the cheapest data plans in the country, and it has customer support in English. Overall, it’s a simple and practical option for those looking for a physical SIM card.

Another benefit of Sakura Mobile is that you can order your card online and pick it up at the airport once you land in Japan. If you’re already in the country, you can purchase it at any official Sakura Mobile store. The only potential issues are that you must unlock your device and check its compatibility with the network here .

Where to buy a SIM card for Japan

Depending on which option you choose, you can buy a Japanese SIM card from the U.S. or from Japan. Personally, I prefer buying mine before the trip, so I feel fully prepared, but there is nothing wrong with purchasing a local SIM at a store or airport in Japan.

Again, we always buy the Holafly eSIM in advance through its website . Then, all we have to do is open our email and scan the QR code. When we need a physical SIM, we order it online through SimOptions, allowing 1-3 business days for it to arrive at our home.

Both of these SIM cards for Japan are easy to install and will allow you to travel with total peace of mind, and with support in your language.

Buy a SIM card in Japan upon arrival

Don’t worry if you’re already traveling or have landed in Japan. You can still get an eSIM for Japan with Holafly , although I recommend checking your device’s compatibility here first. There is also the option of getting a local Japanese SIM card , like the ones I mentioned above. You can find them at several stores, supermarkets, train stations, and airports in Japan.

Just remember that if you opt for a local SIM card, you’ll have to locate a store or retailer, which could take some time. Also, depending on the company, customer support may only be available in Japanese.

Most local cards don’t have unlimited data, so if this is something that’s important to you, I highly recommend getting the Holafly eSIM . Holafly’s Japanese plans range from short-term visits to stays as long as 90 days, and they all have unlimited high-speed data. The closest local competitor is Rakuten Mobile, which has a 30-day plan, unlimited data options, and good rates. However, some travelers have told us that after a few days, the Internet speed slows down significantly.

How to activate a Japanese SIM card for travel

Activating an eSIM or SIM card for travel to Japan is simple. With the Holafly eSIM , just scan the QR code in your email. You’ll have to print it out or send it to a travel companion to scan it.

For any physical SIM card in Japan , insert it into your device and activate the data. You’ll automatically receive an auto-configuration text message letting you know it’s ready to use.

Japanese SIM card compatibility and requirements

To wrap up, I’ll reiterate that we love using the Holafly eSIM for Japan or any other trip abroad. If your phone is unlocked and you’ve confirmed here that it’s compatible, I highly recommend it.

Otherwise, there are several other physical SIM cards for travelers that will let you access the Internet in Japan . Hopefully, after comparing the different plans, you’ll find a suitable option that allows you to browse the Web, do Internet searches, and send messages.

If you have any questions about these prepaid SIM cards for Japan , or you’d like to share your experience, please let me know in the comments below. I’d love to hear from you!

Hi Ascen Aynat,

How is the connection in rural areas in Japan? I’ll be traveling to Kyushu, Shikoku and Hokkaido and will do quite a bit of hiking and therefore away from urban areas. And in that respect is one option (holafly versus a simcard bought in Japan) better than the other?

Hi Yolanda, The connection in rural Japan is actually pretty good compared to other countries. In my experience, Holafly has always come through with a stable connection, even when we’re hiking or travelling in remote areas.

I’m going to Japan next week and will be there for 10 days. If I get a SIM card for 30 days, can my wife use the same SIM card when she going to Japan in a week after I get back? Or are the cards dedicated to one cell phone when activated? Thanks, Jason

Hi Jason, It depends on the card since some allow data sharing, while others are only for one specific device. Of course, take into account how much data each card includes since if you share it, you’ll run out of data faster. In other words, it could be more cost-effective to purchase separate SIM cards for Japan.

How To Get A Prepaid Voice/Data SIM In Japan for Visitors

Visitors to Japan can purchase and use prepaid voice and data SIM cards in Japan. Here are all the details you need to do so.

The Takeaway

• Note: b Mobile has stopped selling their PAY G SIM. So, for now, we recommend getting a regular data-only SIM without voice. For full details, visit our How To Buy A SIM Card In Tokyo page
• b-mobile offers a prepaid voice/data SIM for visitors to Japan.
• The SIM is called the PAYG SIM.
• You can order it online and have it delivered to your hotel in Japan OR
• You can purchase it at Yodobashi Camera shops in Japan.
• After purchase, you must submit scans of your passport photo page, proof of address and your entry stamp to Japan in order to use the SIM.
• The PAYG SIM offers 3GB of data, 60 minutes of calls and is valid for one week.
• You can also purchase a Japan SIM card online to pick up on arrival at Narita, Haneda or Osaka airports.

The Details

• Until recently, it was impossible for visitors to Japan to purchase prepaid voice SIM cards. The best way for visitors to get their own phone number was to rent a phone or use their own phone and risk exorbitant roaming charges.
• This situation changed in 2014 when b-mobile introduced the PAYG SIM prepaid voice/data SIM card. It’s a bit fiddly to purchase and use, but if you’re determined, see below for full details. If not, skip to the end of this page for links to my pages on prepaid data-only SIM cards, and pocket wifi or cellphone rental in Japan.

Check Hotel Availability

Destination, check-in date, check-out date.

Where to Purchase PAYG SIM cards

There are three ways/places to purchase these PAYG SIMs:

• Directly from the b-mobile site .
• At Yodobashi Camera stores in Japan.
• At the Hyatt Regency or Kyoto Royal Hotel and Spa in Kyoto.

After Purchase

• If you order the SIM online, it will be sent to a physical address in Japan that you specify (usually your first night’s hotel). If you purchase it from a store or hotel in Japan, you just carry it out of the shop. After receiving the card, you must do the following:
• Login to the b-mobile user site and enter the SIM details of the card and upload a scan of your passport photo page. If your passport photo page does not show your legal address (and most don’t), you’ll have to upload another form of identification that shows your legal address (a driver’s license etc) in addition to your passport photo page.
• On the activation date (that you specify when you purchase the SIM), b-mobile will send you an email saying the card is ready to use. Insert the card into your phone and set the APN settings.
• Login to the b-mobile user site and upload the same scan of your passport and proof of address, along with a scan of your entry stamp to Japan. This must be done within 24 hours of arrival. If you purchase the card inside Japan, you must do this within 24 hours of the activation date.

Other Options

Needless to say, this rather troublesome process will put off many potential purchasers. In fact, you REALLY have to want your own phone number in order to do this. For most people, it is MUCH easier to do one of the following:

• Buy a prepaid data-only SIM and make calls using Skype. For details, see my How to Buy a SIM Card in Tokyo page.
• Rent a phone and/or a pocket wifi (pocket router). For details, see my How to Buy a Prepaid iPhone SIM Card in Japan page.

Guide to Japanese SIM Cards for Travelers

Should you choose a SIM Card to travel in Japan?

Purchasing a prepaid SIM Card is one of many options for you to connect to the internet when traveling abroad.

Connection to the internet has become nowadays a MUST when traveling to a foreign country, and Japan is not the exception.

The question is: How useful is purchasing a SIM Card when traveling to Japan?

In this article, I will show you this guide to Japanese SIM Cards for travelers: from the variety of SIM Card services to connection speed, and even how to purchase a SIM Card.

I hope this information is useful for you when traveling to Japan.

*Please note that this article contains affiliate links.

Why choose a SIM Card

Since there are many options for you to choose from when it comes to internet connection, it is important to know the “Pros” and “Cons” of using a prepaid SIM Card.

What are the merits of buying a prepaid SIM Card (Pros)

• Relatively cheap
• Easy to use once you are connected
• After your visit, you just dispose of the SIM Card and that’s it.

What are the possible downsides of buying a prepaid SIM Card (Cons)

• Can only be used for one device
• It is not compatible with every mobile phone
• Services usually don’t do refunds if you’re mobile phone happens to not be compatible

5 Best SIM Card services in Japan

Here are 5 of the most popular SIM Card services that you will be able to find for your Japan trip.

Mobal is a MVNO(Mobile Virtual Network Operator) that offers unlimited data cards for 8 days, 16 days, and 31 days. They offer free shipping to most countries in the world as well as various pickup locations within Japan.

The biggest appealing point about mobal’s SIM Cards is that they offer both “data-only SIM” and “data+voice+sms SIM”. The latter one is more expensive, of course, but if being able to use the phone is a priority for you, this is your pick.

Official Website:  https://www.mobal.com/japan-sim-card/

2. Japan Wireless

Japan Wireless offers fixed data limit cards but at a relatively cheaper price. The prepaid SIM Card that they offer is for either 7 days, 15 days, or 30 days with a data amount of 500 MB/day.

Although they don’t offer international shipping, they can send the SIM Card to the airport of your arrival, the hotel where you’re staying, or the nearest post office from you. They also provide support via phone and email, both in English.

Official Website:  https://www.japan-wireless.com/en/rates

3. Simcard Geek

Simcard Geek offers both unlimited data cards and cards with a fixed data limit. Fixed data limit cards are slightly cheaper than unlimited data cards, so if you’re planning on not using the internet a lot, then this might be a good choice for you.

Simcard Geek also provides free worldwide shipping, but depending on the shipping location, it may take between 5 to 12 days in reaching you. So you will need to make the order quite in advance.

Official Website:  https://www.simcardgeek.com/product-category/japan-sim-cards-for-tourists/

4. Japan Travel SIM (IIJmio)

Japan Travel SIM does not have an official website where you can pre-order. But instead, you will find this SIM Card in most electronic shops across Japan. So if you rather go to a shop after getting to Japan to purchase your SIM Card, then this is your choice.

You can also find this SIM Card at Amazon.com, so it is also possible to get it before your trip to Japan.

They offer fixed data limit cards (1GB/30 days, 2GB/90 days) but are rechargeable within the validity period.

Official Website:  https://t.iijmio.jp/en/index.html

5. U-mobile SIM

U-mobile SIM provides data-only SIM cards with a fixed data limit. The prepaid SIM Card that they offer is for either 7 days or 15 days, with a data amount of 220MB/day. This 220MB is high-speed data and if you pass this data amount, your connection speed will fall to 200kbps.

U-mobile SIM is available at the shop counters in the major airports in Japan. You can also find them at Narita airport’s SIM vending machines. Although they don’t provide support and data amount is limited, it is by far the cheapest option.

Official Website:  http://umobile.jp/lp/prepaid_eng/

How to Buy SIM Cards in Japan

There are several ways you can purchase a prepaid SIM Card.

• At the airport: There are shop counters at the major airports in Japan. But be aware that these counters are not opened 24 hours. You can also find SIM Card vending machines at Narita Airport, although they are charged with a surcharge.
• At electronic shops:  SIM Cards can be purchased pretty much at any electronic shop in Japan. If you’re in Tokyo, you shouldn’t have any problem finding a shop where they have prepaid SIM Cards. The largest electronic shops are “Bic Camera”, “Yodobashi Camera”, and “Yamada Denki”.
• Online: Many MVNOs have their own website where you can preorder your SIM Card before coming to Japan. Some services have international free shipping, some have specific points of pick-up such as airports, and others will send it to the hotel where you’re staying. Other than MVNOs, you can also find online travel agencies that offer this service such as Klook. Amazon.com also has SIM Cards that you can buy before your trip.

Some WiFi rental services will also have the option to provide a prepaid SIM Card if that’s the option you want to go with. At Japan Wireless, you can purchase a SIM Card from their website.

Which is Better in Japan, SIM Card or Pocket WiFi

Another thing I would like to suggest is to rent a pocket WiFi. You can rent a Pocket WiFi online just the same as you would a SIM Card, and pick it up at the airport of your arrival or the hotel you’re staying at.

Here is a chart comparing SIM Card purchasing vs Pocket WiFi rental.

• Speed: Both, SIM Card and Pocket WiFi have a high-speed internet connection, even though when it comes to the SIM Card there is usually a daily limit of high-speed connection.
• Coverage: Again, both options have a wide coverage when it comes to internet connection.
• Cost: Although the pocket WiFi rental isn’t that expensive to begin with, it is usually cheaper to buy a SIM Card.
• Practicality: The SIM Card is more practical in the sense that you don’t need to carry around an extra device and worry about the remaining battery amount. Also, in the case of the pocket WiFi rental, it is necessary to return the device (even though not complicated), which is something you don’t need to worry about in the case of a SIM Card.
• Multi-device: The biggest weakness of the SIM Card is the fact that you can use the internet connection only for one device. On the other hand, the pocket WiFi is able to connect multiple devices at once.
• Heavy using: Prepaid SIM Cards tend to have a daily limit amount of high-speed data, and afterwords the connection slows down. Some pocket WiFi also have this problem, but there are also some pocket WiFi rental services that provide unlimited high-speed internet connection.
• Compatibility: If you’ve never used a SIM Card before, then this might be your biggest concern. First, you need to make sure that the mobile phone you’re taking to Japan is unlocked. After that, you need to make sure the SIM Card you’re purchasing is compatible with your mobile phone. This is a concern you won’t have in the case of a pocket WiFi device.

FAQ about SIM Cards in Japan

Q1. How can I install and activate the prepaid SIM card?

This actually depends on the service you’re using. Most SIM Cards are as simple as inserting it into your mobile phone and following the instructions. Sometimes a brief registration process is required in order to proceed, but most times you don’t have to do that.

Q2. How can I know if my mobile phone is compatible with a SIM card?

First, you have to make sure that your mobile phone is unlocked or is a SIMfree mobile phone. If your mobile phone is locked, that means you can’t use the network of carriers other than yours.

Another thing that you need to know is the size of your SIM card. Most SIM card services provide all sizes, but sometimes that is not the case. So be sure to ask before purchasing.

If your mobile phone is relatively new, you have a good chance that you won’t have compatibility problems. But just to make sure, you can search the compatibility of your mobile phone by visiting the “willmyphonework” website.

Willmyphonework Website: https://willmyphonework.net/

Another thing you can do is just ask your mobile phone provider if it’ll be compatible.

Q3. What other alternatives are there to connect to the internet in Japan?

Other than purchasing a prepaid SIM Card and renting a pocket WiFi, there are many other ways you can get access to the internet.

First, there is the Free WiFi That many companies provide. You can find it in airports, train stations, hotels, and some cafes. There are also services where you can rent an entire phone with data included. There is also the option of international roaming which you would have to discuss with your phone provider.

An unconventional way would also be to go to an Internet Cafe. But that would be inconvenient unless you are interested in the experience itself.

As you can see from the previous comparison chart, both the SIM Card and the pocket WiFi have their own strengths and weaknesses.

Prepaid SIM Cards are practical in the sense that you don’t need to carry an extra device, you don’t need to return anything at the end of your journey, and the setting is fairly easy as long as it is compatible.

On the other hand, the pocket WiFi is good for multiple device connectivity and heavy internet usage. You also don’t need to worry about device compatibility.

Personally, I would recommend renting a pocket WiFi. If you’re traveling in a group, it would be cheaper to rent a pocket WiFi as opposed to buying several SIM Cards. Even if you’re traveling alone, it is most possible you’ll have more than one device you’d like to connect to the internet. Plus, the pocket WiFi device is not bulky so it won’t be much of a bother, and returning the device is as easy as putting the set in any postbox in the country.

Now that I have recommended you to rent a pocket WiFi, the next question would be: where can you get a pocket WiFi device?

Usually, you can order one online and the device will be sent to either the airport of your arrival or the hotel you’re staying at for you to pick up.

There are many companies that offer pocket WiFi rental services. Here is an article where I compared some of the most popular pocket WiFi rental companies. I also provide discount coupons at the moment, so don’t miss this chance.

Since I wasn’t born in Japan, I know the cultural impact that you can get when visiting Japan for the first time and what you might be worried about before your trip. And I’ve lived long enough to somewhat understand the nuances of the Japanese culture that make this country such an attractive place to visit. Hopefully I can provide to you both the information you’re looking for and the information you didn’t know you needed to know.

Should I get a SIM Card when travelling to Japan? SIMカード

Prepaid SIM cards allow for high-speed data usage during travels to Japan, but whether or not purchasing one is the best option for an upcoming trip depends on the individual. We'll compare a temporary Japanese SIM card to other popular options for staying connected. 

What is a Short-Term Japanese SIM Card? 

A Subscriber Identity Module (SIM) card is a standard part of any cellular mobile device and allows said device to connect to a network for usage. Oftentimes, visitors to Japan will look into purchasing a temporary SIM card for using international phone data prior to their trip. 

For using these SIM cards in Japan, one can choose the period of valid usage ( 8 days, 16 days, or 31 days ) and then have it sent to their delivery address in their home country prior to departing for their trip. After arriving in Japan, the SIM card can be inserted into their phone or device then configured using the directions found here . Simultaneously, SIM cards can be sent to a traveler's place of stay within Japan after they've arrived.

Be aware that only an unlocked phone  can use the Japanese SIM card, so be sure to check for phone compatibility prior to purchasing. Also note that the SIM card does not support access to phone calls or SNS messaging, but making calls through messenger applications like LINE (the most popular service in Japan), Whatsapp, or another service is possible and largely standard.

In order to assess if a SIM card is the best choice as an international traveler, we’ll compare using a SIM card to three of the most common alternatives; Data roaming with pre-existing phone plans, foregoing individual data and instead relying on free public WiFi , and renting a pocket WiFi device.

SIM card installation

SIM Card vs Data Roaming 

Data roaming is utilizing mobile data provided by a local cellular provider that has a contracted agreement with a provider back in a traveler’s home country.

Roaming varies by provider, individual plans, and the country of travel, so how the conditions of data roaming compare to that of a SIM card varies largely by individual tourists and their phone usage.  

However, in general, roaming entails additional fees added to the base contract costs. For travelers where this is the case, the SIM card may be an enticing option, as it is a prepaid expense with no extra hidden charges.

Data roaming notification

It’s important to note that oftentimes roaming charges are issued on a daily basis with limits set in place, meaning that expenses can stack up quite easily and unexpectedly. On average, U.S. cellular providers will charge anywhere from 10 to 30 USD per day for roaming data in Asia. Other companies may also price roaming on a per-megabyte basis. Through a Japanese SIM card, the unlimited data included in the base price allows for visitors to be connected at all times. 

For those with adequate roaming options already included in their phone plans there will be no issue. However a prepaid SIM card removes a lot of the guesswork that may come for those who do not have innate roaming included in their phone contracts. 

SIM Card vs Public WiFi

For some, foregoing personal data and fully relying on free public WiFi is an option. This is often done as it entails no additional expenses or contractual obligations, but with that, there are a number of drawbacks. 

First off, visitors are often under the heel of WiFi internet accessibility. Though Japan is often celebrated for its technological advancements (and often lives up to such praise), WiFi access is actually somewhat rare compared to other countries like Korea or Taiwan. Public WiFi access is often found in some cafes (predominantly large chain institutions such as Starbucks or Doutor), or places of accommodation . Many train stations offer public WiFi, however, accessing them often require a sign-up or log-in and aren’t always consistent or dependable, though the option is always there for those who need it. 

Additionally, security is a potential issue that may arise when operating solely on free public WiFi.

If someone is handling sensitive or personal information, they should be aware of the risks that may come up. Through a SIM card, data is used individually and kept private, avoiding these security risks. 

So given all these caveats, does foregoing personal data usage for free public WiFi work well for any visitors? For individuals traveling to Japan for business trip purposes and will predominantly be spending their stay at hotels , offices, or meeting spots, depending solely on the internet options provided at these locations may be more than adequate. Though, if one falls under this category, be aware that the security risks still exist. Working with confidential information should be avoided or done with a reliable Virtual Private Network (VPN) service.

SIM Card vs Pocket WiFi

Pocket WiFi devices are one of the primary means of mobile data usage for travelers to Japan. In fact, pocket WiFi devices are often compared and contrasted to individual SIM cards during pre-departure preparations and research due to their similar functions, similar price, and popularity.

Through Japan Experience, pocket WiFi devices are available for rental at a price starting at 44 USD for 5 days and SIM cards are available for purchase at a price starting at 29 USD for 8 days . 

If one has reserved a pocket WiFi device, they will need to pick it up at the airport upon arrival or have it sent to their place of stay within Japan. From here, it is simple to use and just requires a password to connect to the WiFi hotspot. 

A pocket WiFi carries some stand-out benefits, most notably the ability to host multiple connections at once through a hotspot. This is especially beneficial to those traveling within groups or families who wish to share internet access along with those needing to operate multiple devices, like tablets or laptops, during their trip. 

There are some things to keep in mind, however, that may make an individual SIM card the better option for some visitors. As previously mentioned, the pocket WiFi is a separate device that must also be carried around to use. In addition, it has its own power source. While the pocket WiFi has a long and dependable battery life, it will need to be charged and if it runs out of battery, the network will not be accessible. There is also a range limit of 20 meters for hotspot access, and while this is quite far and adequate for most situations, it is something to keep in mind. Individual SIM cards are inserted into mobile devices and thus have no physical accessibility limitations and can be used the entire time without the need of a hotspot connection. 

Ultimately, both options boast a range of benefits for mobile data in Japan and which is best depends largely on the conditions individual travelers will face during their stay. 

Is a Short-Term Japanese SIM Card right for me?

A short-term Japanese SIM Card is a great option for using mobile data in Japan in a cost-effective manner, but its utility in comparison to other options largely depends on a traveler’s specific conditions and needs. Essentially, the continued use of one’s personal device with high speed internet helps to streamline the travel process more, so adequate research for the best options is an essential part of pre-departure preparations. Either a temporary Japanese SIM card or a rentable pocket WiFi device will satisfy the needs of a majority of travelers and ensure that one is connected the entire time of their stay in Japan.

Our Japan and Asia SIM cards all come with data. So it's just a matter of choosing the most suitable plan based on your needs and usage habits. As a general guide, you should  allocate a minimum of 500MB - 1GB of data per day. This will ensure you get the best SIM for your needs, and are comfortably covered for the basics, such as: emails, social messaging, web browsing and GPS.

What's the best SIM for Japan or my trip to Asia?

We recommend our unlimited data docomo SIMs for Japan. They are valid for 15 or 30 days and have excellent coverage across Japan. Of course if you don't need unlimited data, then we also have a 6GB or 10GB data plan which use the SoftBank Japan network.

For travels across multiple or South Eastern Countries in Asia, we recommend our 6GB 8 day or 12GB 16 Day Asia SIM card. The Asia SIMs are extremely versatile and allow you to connect to various networks across the covered countries in Asia. This means no more needing to purchase a separate SIM on arrival in each country.

How do I keep in touch with my family and friends back home?

Our Japan SIM cards and Asia SIM cards are data only SIMs. This means they do not come with a phone number for calls or SMS. Voice SIMs unfortunately require registration with your ID (passport), which is not recommended.

The best way to keep in touch with family or friends is to use data based VOIP apps like WhatsApp, Viber, Line, Skype, Facetime, Facebook Chat etc. As long as your Japan SIM or Asia SIM has data, you can enjoy making voice/video calls and sending texts for free in real time.

Free tracked postage on all SIMs ordered.

The Best eSIMs for Visiting Japan — Tested and Compared

eSIMs are perfect for traveling. Worrying about SIM trays or losing tiny SIMs between the sofa cushions is finally a thing of the past! What’s more, the Japan eSIM market has exploded, with a wide range of offerings from both domestic and international players. To help you choose the best eSIM for your trip, we tried out all the eSIMs that we could get our hands on.

You can get an eSIM with a real Japanese phone number, even if you're just visiting. The voice + data eSIM from Mobal starts at [price amount=4620] for 30 days. Bonus -- the bulk of profits go to charity. -->

Japan eSIMs tested and compared

First, here’s a summary of what we found when we tested the eSIMs: If you’re curious, here’s how we tested the Japan eSIMs .

What exactly is an eSIM?

It’s a virtual SIM that you can download and install onto your phone directly, so no more fiddly physical SIM cards. Most phones released since 2019 have the option to use an eSIM, with Apple’s US iPhone 14 and 15 being eSIM only. eSIMs are convenient when you want to change your carrier, such as when abroad, as you can connect to a new provider in seconds without removing your existing physical SIM card.

Japan eSIMs for tourists and short-term visitors

Here’s a quick overview of some of the Japan eSIM options for your trip. This is not an exhaustive list; just an introduction to some of the main players in the market.

eSIM Japan: Affordable, reliable and easy

eSIM Japan offers economical data-only plans for visitors to Japan. Their plans come in two varieties: a general Japan plan, and city-specific plans for Tokyo, Osaka, Kyoto and more. They are all the same price, and for all intents and purposes are the same as the general plans. However, all plans work throughout Japan.

When we ordered the 2GB/day Japan Unlimited Pro eSIM, a QR code landed in our inbox immediately, so you can even decide to pick one up while waiting to pick up your luggage at the airport. The time from purchase to use took less than 15 minutes.

The plan begins as soon as you scan the code and install the eSIM. Plans have a set time limit (3, 5, 7, 12, 15, or even 90 days) and a data limit (3GB, 5GB, 10GB, or unlimited), so you can choose a plan that works for the length of your trip. Plan prices vary based on length, from US$ 3.99 for a basic 3-day plan, to US$ 26.99 for an unlimited 12-day plan.

eSIM Japan is provided by China Mobile Hong Kong, but roams to Japan’s KDDI au and SoftBank networks (you’ll need to enable roaming to use it). Despite the roaming, it was fairly fast, with a download speed of 38.27Mbps on average. Webpages loaded in a flash, and both video calling and streaming were smooth, with no lags.

Note: If you are in Hong Kong or Taiwan, you’ll need to use real-name registration. Otherwise, no signup is required.

Mobal eSIMs: Best for emergencies and heavy data users

Popular local provider Mobal recently launched a line of eSIMs for Japan. They sell seven different data-only eSIMs, ranging from a basic 1GB, 8-day eSIM for ¥ 1,920 , all the way up to a hefty 100GB, 31-day eSIM for ¥ 8,000 . They also have a voice and data SIM.

Mobal uses the major Japanese network Docomo, which means that you won’t be roaming. It’s 4G LTE and coverage is countrywide. For activation of the data SIMs, it takes about 15 minutes. We received an email with a link to their service website after 5 minutes. This led us to a page where we waited for our eSIM QR code to be ready for another 10 minutes.

In terms of performance, Mobal is about middle of the pack, at an average of 24.76Mbps. Websites loaded quickly, and video calling was fairly smooth. Overall, it’s a solid, reliable eSIM.

Mobal voice + data eSIM for Japan

There is also a voice + data eSIM , which has an initial fee of ¥ 2,970 . When you activate your eSIM, you’ll need to choose a monthly plan, ranging from 1GB/month for ¥ 1,650 , to 30GB/month for ¥ 4,378 . There is no minimum contract period, and there are no cancellation fees, making it a viable choice for both travellers and residents alike. You get a real Japanese phone number with this eSIM. We tested out the 7GB plan.

Note: Due to regulations in Japan, the voice + data eSIM cannot be emailed to customers; your access code will need to be posted to your residence overseas, or otherwise picked up in person in Japan. You need to apply in advance, upload an ID document and wait for a delivery. Once you get your package in the mail, you need to activate your Mobal eSIM on the Mobal website. You’ll enter a 32-digit EID, then wait for Mobal to activate your eSIM and provision your new Japanese phone number. Technical support is available via email and a web form, though most questions can usually be solved by having a peek at Mobal’s FAQs page.

Airalo: Good performance from a trusted brand

Special offer: Order through our link and get 10% off. The discount is automatically applied at checkout.

If you’re in the market for speed, Airalo isn’t going to play games with you. Airalo eSIMs roam on SoftBank, one of Japan’s major carriers, offering dependable data on the go. Their Moshi Moshi eSIM line of eSIMs has 7, 15, and 30-day packages. The 7-day package is the bare minimum, with only 1GB of data for US$ 4.50 . The 15-day plan offers 2GB, and at the upper end, the 30-day plans come in 3, 5, 10, and 20GB increments. For those of you who burn through your data, that 20GB package will set you back US$ 26.00 .

Getting the Airalo eSIM took no time at all. We signed up for the 2GB/15-day Moshi Moshi eSIM, and after paying, we were immediately taken to a page with our eSIM QR code waiting. We were 100% good to go within 15 minutes. Note that sign-up is required for this eSIM.

When it came to our speed test, this eSIM left all of its competitors in the dust. Our testing had a lightning fast average download speed of 141.61Mbps. Websites loaded almost instantly, and YouTube videos didn’t stop to buffer once. Even our awkward video calls didn’t make this eSIM break a sweat. If you’re the sort of person who really works your data to the bone, Airalo is a good choice.

Ubigi: Solid performance with easy order and setup process

Ubigi is a global eSIM provider currently offering eSIMs for over 200 destinations. A relatively new name in the Japanese eSIM market, they nonetheless have plans to cover most needs. From economical single day 500MB plans for ¥ 390 to beefy month-long plans with 50GB of data for ¥ 9,700 , there’s something for all travelers.

Ordering from Ubigi is a snap. Once we paid, we had a QR code emailed to us in seconds. One quick scan, and we were ready to go. Like most others on this list, Ubigi works with NTT Docomo for reliable coverage across Japan. The company behind Ubigi is Transatel, which is actually owned by NTT.

We tried the 3GB Ubigi eSIM. In our testing, we experienced average speeds of 73.72Mbps, and webpages loaded in a flash. YouTube playback was smooth with no buffering, and our video calls were lag-free. Overall, at this price point, Ubigi offers excellent quality and speed that make them a strong contender.

World eSIM: Good speed from a trusted Japanese provider

World eSIM is brought to you by Vision Inc. — the folks behind travel wifi name Ninja Wifi . They have nine Japan eSIMs, with various combinations of data and validity periods. We ordered the 3GB/5-day plan for US$ 8.50 , but you can also get 5GB/10-day, 10GB/15-day, and 15GB/20-day eSIMs. If you prefer to get a daily amount of data, there are 500MB/day x 3 days ( US$ 4.50 ), 1GB/day and 2GB/day options.

Getting our eSIM was straightforward. After signing up on the World eSIM website, we paid and had a QR code sent to our email instantly. A quick scan, and we were ready to go. Download speeds averaged 99.15Mbps, and our streaming was smooth. We found that this was one of the best eSIMs for video calling, during our test. It’s a solid choice, overall.

Sakura Mobile: Trusted local Japan provider

An established SIM and wifi provider that’s popular with people staying in Japan both short and long term, Sakura Mobile also has a line of eSIMs. Prices scale depending on how long you’ll be staying (up to a maximum of 90 days), and how much data you want. Their cheapest option — a 3-day, 1GB data-only travel eSIM, costs ¥ 2,100 .

We tested the 3-day, 3GB data-only eSIM, which cost ¥ 2,750 . There was no option to install it directly through the Sakura Mobile website; the QR code and instructions were emailed to us. The user interface was a little clunky, but we managed to get the eSIM set up in under 15 minutes. We didn’t need to activate roaming to use it.

In terms of performance, Sakura Mobile’s download speeds averaged 84.46Mbps, although they varied significantly across test platforms. Video playback as well as calling was smooth, though, and we were satisfied with the overall performance.

Jetpac: Good price and performance

Singapore-based eSIM player Jetpac have a range of plans for Japan, starting from 3GB for ¥ 1,500 and going up to 25GB for ¥ 3,765 . When we did our test, there was also a promotional 1GB plan for ¥ 150 . We opted for the 3GB eSIM, however. Once we had paid, the Jetpac eSIM was provisioned instantly.

When it comes to speed, the Jetpac eSIM was one of the top performers during our tests. Download speeds averaged an impressive 122.7Mbps, and streaming as well as video calling was super smooth.

You need to enable roaming to use the SIM, though once up and running it will roam on the local SoftBank and KDDI networks. Jetpac pushes customers towards their app, but it’s not actually necessary to download it. A nice little perk is that the Jetpac eSIM gives you access to 1,100 airport lounges around the world; you can use them in the event of a flight delay or cancellation.

Which is better for your Japan trip: An eSIM, or a physical SIM card?

Even with more providers arriving on the scene, the options with physical SIMs are still superior to what you can get with eSIMs. For example, only one of the eSIMs listed here includes a Japanese phone number with calling ability (that’s Mobal ). So if you’d like something more inconvenient but with better options, check out our guide to prepaid SIM cards for travel to Japan .

Also, keep in mind that you might need a second device to install an eSIM, as the second will display the QR code for your first device to scan. If you don’t have a second device, you’ll need some help to install the code — perhaps by asking someone to take a photo of your QR code and then scanning it from their phone.

How did we test the Japan eSIMs?

First of all, a disclaimer: Testing the performance of eSIMs is inherently difficult, due to transient network conditions. You can test the same connection, on the same phone, in the same place, twice in a five-minute interval and get two completely different results for speed and latency.

For our most recent test, we rented six identical Google Pixel 7a handsets, and took them to a studio in Tokyo to test out the eSIMs mentioned in this article. While our video producer recorded the tests, our CEO installed the eSIMs and went through the following:

• Five speed tests, all using the Ookla app and different test servers, assessing the download and upload speeds (we did four tests for upload speeds), as well as latency
• Watched videos on YouTube to assess streaming capabilities
• Made short video calls to look for lag

Our CEO then retested some of the eSIMs the following day, at a different location in Tokyo, to compare results. Due to both Mobal and Sakura Mobile experiencing severe throttling on the initial test day, we have used the data from the second day for their eSIMs.

Some of the eSIMs had to be run on the same device, meaning that not all tests were simultaneous. We know that our testing method isn’t perfect, but it gave us a good idea of the performance of the different eSIMs. We excluded some eSIMs from the article where we had concerns about the ordering process, performance or pricing.

A word on speed tests: We strongly recommend that you don’t run speed tests with your eSIM, as they BURN through data. A single test could use 300MB or more!

While we do our best to ensure everything is correct, information is subject to change. Prices are approximate. This post was first published in October, 2020 and was last updated by Carey Finn on April 1st, 2024.

The Best eSIM Cards for Japan Travel in 2024

Planning a trip to Japan soon? I’ve been there, and let me tell you, staying connected is key to making the most out of your experience. From navigating the bustling streets of Tokyo to finding that hidden ramen spot in Kyoto, a reliable internet connection is your best friend. That’s where eSIM cards come in handy, offering a seamless way to stay online without the hassle of physical SIM cards.

Top eSIM for Travelling Japan

When planning my trip to Japan, eSIMX caught my eye primarily because of its affordability and ease of use. For just $4.5 USD , I could get a 1GB plan valid for 7 days, perfect for my short Tokyo escapade. Setting it up was a breeze; all I needed to do was scan a QR code, and I was instantly connected. What I loved about eSIMX was the option to choose from various data packages, ensuring I had just the right amount of data for my needs. Whether navigating Tokyo’s bustling streets or hunting down the best ramen in Kyoto, eSIMX provided me with uninterrupted connectivity.

Next, I explored Airalo’s Moshi Moshi packages as a comparison. Interestingly, their starting price of US $4.50 for a 1GB, 7-day plan was identical to eSIMX’s offering. However, Airalo provides a wider range of validity options, catering to short and extended stays. The simplicity of purchasing and activating the eSIM and extensive coverage across Japan made Airalo a strong contender for my connectivity solution.

ESIMJAPAN appealed to me due to its varied plans, which included an impressive unlimited data option starting from only $3.99 for 3 days. This was incredibly enticing for someone like me, who’s heavily reliant on data for everything from navigation to streaming. Their 10GB plan at $18.99 valid for 20 days was also a great deal, considering the promised high-speed 4G LTE connectivity.

Holafly stood out for its sheer simplicity and the promise of unlimited data. For just $6.00 USD , the ease of receiving a QR code and instantly connecting to the best network in Japan without any registration was too good to pass up. Plus, the option to keep my WhatsApp number was a significant advantage, allowing me to stay in touch with family and friends effortlessly.

GigSky was another interesting option, with a unique offer of 100 MB for free for the first 7 days – perfect for travelers who might need an emergency fallback option. Their plans ranged up to $49.99 for 10GB over 30 days, which, while a bit pricier compared to others, offered the flexibility and peace of mind that comes from not requiring a credit card upfront.

Finally, Maya’s diverse plan durations and clear pricing structure intrigued me. Whether I needed 3GB for $10 USD or unlimited data for $56 USD , all for 10 days, Maya presented a clear, straightforward choice without any hidden fees. The upfront pricing and flexible options made it an attractive choice for managing my data needs in Japan.

Each eSIM provider offered unique advantages and conveniences, making the decision highly dependent on my travel needs and data requirements.

Benefits of Using eSIM Cards in Japan

Convenience

One of the biggest draws for me when using an eSIM card in Japan is its sheer convenience. No physical SIM cards mean there’s no need to visit a store or swap anything out of my phone upon arrival. I can set everything up before my plane even touches down. This ease of use extends to managing my data plans as well. With an eSIM, I’m not tied to a single provider for my stay, allowing me to switch between plans or providers based on my current needs. Keeping my primary number active while using a local data plan is a game-changer for staying connected without racking up exorbitant roaming fees.

Cost-Effectiveness

Going into my travels, I’m always looking for ways to cut unnecessary expenses, and eSIM cards in Japan help me do just that. Traditional SIM cards usually come with hidden fees or rigid plans that don’t always fit how I use my data. However, eSIM plans tend to be more flexible and transparent with their pricing, making finding an option that fits my budget easier. Here’s a quick comparison of the cost between different eSIM plans I considered for my trip to Japan:

This table highlights the diversity in plan options, showcasing price, and data allowance flexibility . It’s evident that whether I’m looking for a short-term solution for a week-long trip or need unlimited data for a month, there’s an eSIM plan that can meet my requirements at a fraction of the cost of traditional roaming services.

How to Activate an eSIM Card in Japan

Embarking on a journey to Japan, I discovered the seamless transition offered by activating an eSIM card . Here’s a step-by-step guide I followed, ensuring I stayed connected throughout my travels.

Step 1: Check Device Compatibility

First off, I had to ensure my smartphone supported eSIM technology. Not all devices are equipped with this feature, so verifying before moving forward is crucial. Most newer models of iOS and Android devices are eSIM compatible, but it’s always safe to check the manufacturer’s website or contact customer service for confirmation.

Step 2: Choose a Provider

With a compatible device, the next step was choosing a provider. The options were plentiful, each offering varying data plans, coverage, and pricing. I found it helpful to consider factors such as the length of my stay, my data needs, and the presence of customer support in English. After comparing several providers, I settled on one that balanced cost and connectivity coverage.

Step 3: Purchase and Download eSIM Profile

Purchasing an eSIM plan was straightforward. I did it online, directly from the provider’s website. After payment, I received a QR code via email, which is the eSIM profile I needed to download. It was essential to be connected to Wi-Fi for this step, as my device required internet access to download the eSIM profile. Scanning the QR code with my phone’s camera initiated the download and installation process, completed within minutes.

Step 4: Activate eSIM on Your Device

The final step was to activate the eSIM on my device. This involved entering my phone’s settings and navigating to the Cellular or Mobile Data section. I could add a new data plan by selecting the eSIM I had just installed. Following the on-screen instructions, I activated the eSIM and chose it as my primary data line for my stay in Japan. Seeing the cellular bars light up was a relief, indicating I was connected and ready to explore Japan without missing a beat.

Tips for Using eSIM Cards in Japan

When I started planning my trip to Japan, one of the main things I knew I’d need to figure out was how to stay connected. After settling on an eSIM as my go-to, I’ve picked up a few tips and tricks that made the whole process smoother and the usage more efficient. Here, I’ll share what I’ve learned about saving data, ensuring device compatibility, and staying connected for emergencies.

Saving Data Usage

While exploring the bustling streets of Tokyo or the serene landscapes of Kyoto, it’s easy to get carried away with data usage. I quickly learned that managing my data consumption was key to avoiding unwanted charges and ensuring my eSIM lasted throughout the trip. Here’s what helped me:

• Use Wi-Fi Whenever Possible : Japan has free Wi-Fi spots, especially in major cities and public areas. Connecting to these can save a significant amount of data.
• Download Maps Offline : Before heading out for the day, I’d download the areas I planned to explore on Google Maps. It’s a simple step that saved me data and stress, especially in areas with spotty coverage.
• Monitor Your Data Usage : Most eSIM providers have an app or a dashboard where you can check your data usage. Keeping an eye on this helped me adjust my activities to ensure I didn’t run out of data.

Ensuring Compatibility

Before diving into eSIMs, making sure my phone was compatible was crucial. Here’s a quick rundown of what I did:

• Check Device Compatibility : Not all devices support eSIM technology. I checked the specifications of my phone on the manufacturer’s website before making any decisions.
• Contact Your Current Provider : Some carriers lock devices to their network, making using an eSIM from another provider impossible. I gave my current provider a call to ensure my phone was unlocked.
• Software Update : Keeping my device updated ensured I had the latest eSIM management software, making the setup process smoother.

Emergency Connectivity

Even the best-planned trips can encounter hiccups, so being prepared for emergencies is essential. Here’s how an eSIM gave me peace of mind:

• Keep Important Contacts Stored : I stored essential contacts on my phone, including the local embassy and emergency services. Accessibility to these numbers without fumbling through the internet was reassuring.
• Have a Backup Plan : Despite the convenience of eSIMs, I also kept a physical SIM card as a backup. If I encountered any issues with my eSIM, I wouldn’t be left stranded without connectivity.
• Understand Your Provider’s Support Options : Knowing how to reach my eSIM provider, whether through an app or hotline, gave me confidence that I could resolve any issues quickly, no matter where I was in Japan.

Navigating eSIM cards in Japan with these tips in mind made my experience enjoyable and, most importantly, stress-free. From Akihabara’s neon lights to Nara’s historic temples, I remained connected, informed, and ready to explore all Japan had to offer.

Navigating Japan with an eSIM card was a game-changer for me. By monitoring my data usage and ensuring my phone was compatible, I managed to stay connected effortlessly.

5 Best SIM Cards at Narita Airport | Unlimited Data Options

Published on 2022-06-06 by Sakura Mobile

In order to enjoy your trip to Japan to the fullest, you are going to need to get a SIM card soon after you arrive at Narita Airport.

However, there are many different providers that you could choose from, all with different plans and prices.

Upon arriving at Narita Airport, the following questions might come up:

• Which SIM card should I buy?
• I don’t want to buy a cheap SIM card if it isn’t going to work properly.
• I want someone to tell me what criteria I should be looking at when choosing a SIM card.

Rest assured.

In this article, we will be recommending to you 5 of the best SIM card providers at Narita Airport.

We have included a comparison of each of the providers so that you can decide which SIM card is suitable for you.

Pickup and return

Things to be careful of when buying a prepaid sim card, for long-term stays (more than 3 months), consider getting a long-term contract, japan does not have free wifi so be sure to get a sim card.

• Reserve a SIM card in advance on the internet
• Will you have enough data?
• Is there good English support?

Below we will go into more detail about each point.

1) Reserve a SIM card in advance on the internet

If you have the option to reserve your SIM card in advance, we recommend taking it. This has the potential to save you lots of money. For example, you can save 2,000 JPY on an 8-day SIM card just by reserving it online.

You might be thinking that you want to avoid the hassle of navigating through a website and just buy directly at the airport. However, this is not recommended as airport counters have a limited amount on stock.

If you arrive at the airport and the counter that you visit is out of the product you are looking for, you will have to survive in Japan without internet connection until you can get a SIM card from a different provider.

To avoid unnecessary stress, reserve your SIM card online.

2) Will you have enough data?

If you are not sure about the amount of data that you will be using on your trip, we suggest that you go with unlimited.

Japan’s options for free WiFi spots are very limited, and it would be a large inconvenience to have no data when you need it.

Some companies will give you a set amount of data for the number of days that you are traveling. There are times when this is the cheaper option, but if you want to use your phone as much as you want outside of your hotel room, it would be wise to get unlimited data to save stress.

3) Is there good English support?

It is easy to disregard English support by assuming you pick up your SIM card from the airport, put it into your phone, and after that do not have to deal with anything else.

However, there may be times during your trip when the SIM card malfunctions or does not connect properly. In these cases, having English support to help you solve your problems can be a lifesaver.

Not only that, but it is important to make sure customer support can be reached in various ways. In the best-case scenario, you will be able to contact your provider through email, live chat, and the phone.

About prepaid SIM cards with phone numbers

In Japan, there are little to no prepaid SIM cards sold with a phone number. In general, travelers to Japan will only be able to purchase what is called a data-only SIM card.

This is because the ID verification process surrounding getting a phone number is very strict in Japan. It is difficult to sell SIM cards with phone numbers due to these regulations.

There are a few companies that do advertise prepaid SIM cards that include a phone number, but some of them may be operating illegally. If you are looking to purchase one of these SIM cards, you should be aware of the risks.

Even with a data-only SIM card, you will have the ability to use applications like Skype or WhatsApp, so it may be wise to use these when you want to make phone calls.

Returning your SIM card

You may be wondering if you have to return your SIM card at the end of your stay. There should be no worries there, as you can simply dispose of your Sakura Mobile SIM card when you are done using it.

Not having to think about the return process of a SIM card can be helpful for those who are worried about the steps to returning or are simply forgetful.

Is your phone unlocked?

If your phone is locked, it will not be able to take SIM cards from other carriers. This means you will not be able to use a SIM card from Japan properly. If you are unsure whether or not your device is unlocked (also referred to as SIM-free), you will need to contact your cellphone carrier.

Additionally, you may need to directly visit the carrier in your home country to get your phone unlocked, so make sure to confirm this before you travel to Japan.

What size SIM card does your phone hold?

If you have never changed the SIM card in your phone before, it may be news to you that there are three different sizes of SIM cards. You can find them in regular, nano, and micro sizes.

When you buy a prepaid SIM card, be sure to choose the right size.

Sakura Mobile’s SIM cards all come with a free adjuster, so you can use the SIM card no matter your device.

Is your phone compatible with Japanese frequency bands?

There are certain network signals used in Japan that may not be compatible with your device. The docomo network which Sakura Mobile is on uses Band 1 and Band 19.

We are aware that network compatibility is likely a new concept to many, so feel free to reach out to our customer support team if you have any questions.

For more information and to check whether or not your device is compatible, visit this page .

• Sakura Mobile SIM card device compatibility

If you are unable to get any of the above points figured out before coming to Japan, we recommend that you purchase a portable WiFi device instead of a SIM card. This will allow you to stay connected even if your phone is not unlocked, the SIM card does not fit, or your device is not compatible.

Sakura Mobile also offers Pocket WiFi for travelers; check out the link below if you are interested.

• Sakura Mobile Pocket WiFi plans

However, Japan only has these spots in places like fast-food restaurants or coffee shops, and some of them do not work at all. Not to mention that you will not be able to find these kinds of places when you explore rural Japan or while you are riding a train or bus.

To avoid the stress of having to scramble for free WiFi everywhere you go, we strongly recommend that you have a plan for getting a SIM card before landing in Japan.

Especially because of the large amount of SIM card companies at Narita Airport, it can be hard to decide which provider to choose from.

Each company differs in its prices and the plans they offer, so make sure to look carefully and choose based on your own needs and priorities.

We hope that this article helped you narrow down which SIM card provider you want to use in Japan.
