What’s the best tourist SIM card for Japan (2022-2023 guide)

What’s the best tourist SIM card for Japan?

The broadband cellular networks have spoiled us.  We’re used to having all the information available at the snap of a finger. 

Not all the screen time is spent equally well, but to be honest, I would be completely lost in some situations if they took my smartphone away.

That is certainly also the case abroad.  In Japan we used our smartphones to navigate the vast cities, to find recommended places to eat and cat cafés, and to look up the train and metro schedules.

But before you start browsing the internet on your smartphone in Japan you better check your telephone provider’s roaming tariffs. 

A few MB’s of data will often cost you a whopping 100 dollars, which means you’re almost always better off with a prepaid Japanese travel SIM card. 

Not only will it cost you less, but the quality of your connection will most probably also be better.

In this article, I will describe the best options to get your hands on a local SIM card.  The easiest option is to buy one in advance online as this gives you time to compare all the different options. 

Don’t worry if you’re reading this article on the day of departure or when you’re already in Japan.  You can also buy a SIM at the airport or in an electronics store in Japan.  I will guide you on how to do this further down in this article.

The main focus of this article is on the different prepaid SIM cards available to tourists in Japan, so-called Japan travel SIM cards, but we also cover options for those who will be staying longer in the country such as students and expats.

In a hurry? Our picks for the best Japanese SIM cards

We updated this post in October 2022.

If you are short on time or you don’t want to read the complete post, these are our top choices: 

Why buy a Japan SIM card

We used our data connection a lot in Japan

The two apps we probably used most were Google maps to find our way while walking and the metro app, such as this one in Tokyo, to plan the best route to our destination.

Here is an overview of more great apps for traveling to Japan. 

Major cities such as Tokyo and Osaka are very expansive and you will use the metro a lot to get from one site to another.

In addition to that, we used our smartphones to find restaurants, translate menu items and learn more about the many places of interest.

Japan SIM cards are relatively cheap, certainly much cheaper than paying data roaming costs, and our local Japan SIM turned out to be priceless, maybe even more so than in other countries we visited.

The larger cities also count numerous WiFi hotspots so we also tested if these work well and if they’re sufficient to replace the need for a local Japanese SIM card.

Free WiFi in Japan

A lot of places offer free WiFi.

If you want to avoid the cost of paying for a Japan travel SIM you could try to rely on these public hot spots.  The Tokyo Metro has free WiFi, Starbucks offers free WiFi to all its customers (there was a time you used to register in advance but this is no longer necessary) and most restaurants have free WiFi as well.  

Cities are also adding WiFi hotspots in major public spaces by transforming public phone boots into WiFi hotspots. 

We tried some of these hotspots but as we had our local SIM with our pocket WiFi device we only used them occasionally. 

The Tokyo Metro hotspots didn’t seem that reliable, they usually did not work for us, WiFi offered by restaurants was usually of excellent quality and very fast.

The free WiFi hotspots are a nice and welcome initiative but their coverage falls short if you really need to rely on these places to access the internet.

If you use free WiFi hotspots you also need to be aware of the security risks.  Hackers may put themselves between you and the connection point thereby reading along with everything you send over the connection.

The WiFi hotspots are useful but there are not enough to be able to truly rely on them.  If you’re used to using your smartphone a lot during your trip our advice is to buy a prepaid SIM card for the duration of your vacation in Japan.

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 ¥2,800 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 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 ¥4,000 and JPY ¥5,000 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 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 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.

Short stays

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.

Mobal Tourist SIM

Longer stays

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.

There’re all kinds of Pocket WiFi devices but most are about this size

Pocket WiFi versus a Japan tourist SIM 

You can choose to install your local SIM on your phone or you can opt to use a pocket WiFi device, both have their advantages and disadvantages. 

Based on my own experience I will try to advise on both of them.

Pocket WiFi for Japan

The main advantage of using a pocket WiFi device is that you don’t need to touch your phone. 

All your settings can remain unchanged, you just need to make sure that your data connection is disabled to avoid any nasty data roaming fees. 

Your SIM remains in your phone which means that friends, family, work relations, and anybody else who has your phone number can reach you as if you were home.

If you want that people can reach you at all times then this is probably the best option.

Another advantage of a pocket WiFi device is that you can share the internet connection with several users at a time (most devices support up to 10 parallel connections).  Alternatively, you could install the SIM in a phone and share its internet connection by enabling the phone’s hotspot.  This would, however, drain the phone’s battery quickly.

A disadvantage of a pocket WiFi device is that it is one extra device that you need to carry around and that you will need to charge on a daily basis if you use it frequently.

SIM card in Japan

Installing the SIM in your phone is by far the most practical option if you don’t plan on sharing your connection and if you don’t mind that you temporarily can no longer be reached on your known mobile number. 

Some local SIM cards support voice+data. 

If you opt for such a SIM you will get a local phone number which you could share with relatives at home.

In these modern times, you could also use Skype to keep in touch with your home base, and then a data SIM card is all you need.

Our focus for this article is to help you choose the best SIM card for Japan. 

We list all the important features of the available SIM cards so that you can choose the one that best suits your needs.

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. It used to be a virtual operator but it is now building out its own network. Today it covers about 94% of the population. Their customer relations team only speaks Japanese.

There are several other providers but these typically piggyback on the network of these 3 majors to offer their services.

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

Au by KDDI is seen as the least reliable network of the major players.  They do well in terms of coverage but their reception is not as good inside buildings or underground due to the frequencies they’re using.

What you need to know and check before buying a Japan travel SIM

Here we share the most important things you need to know and check before buying a Japan travel SIM.

What you need to know before buying a SIM card for Japan

Before buying a SIM card for Japan, check which size of SIM card you need and if  your phone or pocket wifi device works in Japan

Which size of SIM card do you need

SIM cards come in 3 sizes. 

Originally only the standard SIM existed.  Over the years the size has decreased, first to the Micro-SIM and then to the Nano-SIM

The technical specs of your phone or device will tell you what SIM you need.

Most of these providers use multi-size (3-in-1) SIM cards.  Others only offer 2-in-1 (Micro and Nano) which means they will still be compatible with most current models. 

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

Does your phone or pocket WiFi device works in Japan

It is of course of crucial importance that your phone or device is compatible with Japan’s telecom network.

More specifically they need to be able to operate on the bands that the telecom operators in Japan are using. 

You find this information in the technical specs of your phone and/or WiFi router. 

You can also check this page where you can select your phone and the network operator to verify if they’re compatible.

What to check before buying a Japan travel SIM

Here’s what to look for when choosing your Japan travel SIM.

Data or Data + Voice

Data-only SIM cards are by far the most popular and here you have the most choice. 

For most visitors, these SIM cards will be all they need as you can call using Skype or other similar tools such as Whatsapp. 

If you do need a local phone number you can choose a Data+Voice SIM.

Duration

All prepaid SIM cards can be used for a certain number of days.  This period starts when you activate the SIM and it cannot be extended.

Data allowance

Most SIM cards offer unlimited data, while others have a limit on the data that you can use.   

If you think your data allowance won’t be sufficient you can choose one which allows you to top up on the go.

Region

All the SIM cards listed in this article will work in Japan and some will even work in other countries. 

These so-called multi-country SIM cards may be useful if you will combine a visit to South Korea or other countries with your trip to Japan.

Pick up

Some SIM cards are shipped (for free) to your home address or you get the choice to pick them up at the airport.  Others can only be picked up at the airport.

Preorder your Japan SIM card online

Here’s an overview of the different prepaid SIM cards you can preorder online.

The overview is organized by provider. 

For each, we list the most important details, if you need more information you can click on the associated links.

The advantage of ordering your SIM in advance

If you have just come from a long-haul flight, you are probably drowsy and not in the best shape to make a decision about which SIM you need. 

For this reason, we advise you to pre-order your SIM online and have it sent to your home address or ready for pick-up at the airport.

Another advantage of ordering online is that you can take all the time you need to compare the different options.

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.

Below providers offer SIM cards that are either shipped to your home or that can be collected in your airport of departure.

If your phone supports eSIMs you can also use an eSIM for your Japan trip. The email with everything you need to get connected in Japan will be sent within 24 hours of booking.

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

If you’re already in Japan when you’re reading this you shouldn’t worry. 

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 (see here and here).  The sales points from the operators will likely be able to better assist you and give you advice. 

These stores from BIC camera will 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. 

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.

Online

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. 

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.

Mobal

Mobal offers an alternative. 

Their long-term plan comes with no minimum duration, no activation, and no termination fee. 

The customer service team speaks English, is super-responsive and you can easily order the SIM card online.

This is what you will get:

Japanese Phone number: A real Japanese phone number starting with 070, 080 or 090 (Softbank).  A voicemail service is included.

Conclusion

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 (October 2019).
