Where to buy a SIM card for Japan?

This destination could easily be the mecca of technology, and Japan has become one of the pioneer countries in innovation. Thanks to all the advances nowadays, buying a prepaid SIM card from home is very easy before you even start your trip. Online stores all over the world offer international SIm cards for destinations like this one. This solution has improved other more expensive services such as roaming or pocket wifi

Although virtual solutions have greatly improved the market, you can also buy local SIM cards for tourists from operators in Japan. In the country, one main operator and nine other companies operate as MVNOs, from which you can buy services for tourists. We recommend that you buy your SIM card before arriving in Japan, but we will tell you a little about all your alternatives.

Easy to buy

As we already mentioned now, prepaid SIM cards are very easy to buy even before your trip starts. This is thanks to the great variety and quantity of online stores where you can find remote SIM cards for Japan. You usually find more offers for tourists in these stores than in Japanese operators.  And, of course, most of the online stores have English websites as opposed to how to buy a SIM card if your Japanese is not polished. 

However, you can also buy your local SIM card through a physical store or distributor in Japan. You can find options as soon as you arrive in the country, including some at international airports and small retailers around the country. Always keep in mind that it requires more processing on your part to purchase a SIM card this way.

Buy before you travel.

If you don’t want to worry and spend extra time, the best option is to buy your international SIM card from an online store. This way, you will have already figured out how to get mobile internet in Japan before you arrive. The websites of these stores are very easy to use for any kind of user, having several means of communication at your disposal. Also, it will not be difficult to find a plan that suits you because they have a wider variety of plans for tourists. 

Another positive point of buying a SIM card this way is the cost you can save compared to other solutions. Before choosing a provider and making the purchase, we would like to recommend you check a couple of points. The first one is that you should take into account if your phone uses the same frequencies as the local networks in Japan. The second is that you should take into account that the SIM card, even if purchased remotely, uses one of these networks. For this reason, you should choose one that connects to a network in Japan with good coverage and speed within the cities you plan to visit.

Buy upon arrival

This is the way that we could consider as traditional but nowadays less efficient, and that is to wait to arrive in Japan to solve your communication. In this sense, there are not many surprises; once you get off the plane, you should look for a physical store to buy a SIM card. You must take into account all the above about compatibility and networks; if you didn’t do it before arriving, it might be more difficult once you get there. Also, don’t expect to find many English-speaking stores, so most will be in the local language. 

Now that you know how to buy a local SIM card in Japan, you should know what the local operators are. There is one main network operating in the country, and that is SoftBank Japan. Other companies also sell services for tourists, but they all use the SoftBank network. Some of these are NTT Docomo, Comst, and Bmobile Japan. All of them have outlets all over the country.

There is a big operator called SoftBank, which has the infrastructure of the only telecommunication network in Japan. Along with this company, there are nine other MVNOs from which you can buy local SIM cards for tourists. Thanks to the country’s many offers, it is easy to find physical stores in many places. In the most important cities, in international airports, malls, 7-eleven and more, there are stores of these operators for you. 

Don’t forget that language can be a challenging issue in Japan, so we recommend buying your prepaid SIM card before your trip. Otherwise, you will have to use one of the local stores and go through the registration process for your SIM card once you buy it.

How much does a SIM card cost to travel to Japan?

Still, if you want the combination of good service, good prices, and affordable for everyone are the virtual SIM cards from Holafly for Japan that we will present to you now.
