Actually, for many reasons, the best way to buy your SIM card for Japan is through an online store. However, as we said at the beginning, another way you can take it is to buy it through a local Japanese operator once you arrive at your destination. If you are not related to the local companies, we will discuss the Japanese operators you can find.

NTT Docomo

This is known as one of the largest telecommunications companies in Japan. Its reach is such that it has about nine Mobile Virtual Network Operators (MVNOs) through which you can purchase their services. Among these providers, we can find Bmobile, Sakura Mobile, Mobal, and others. All of them offer prepaid SIM Card services for Japan supported by the NTT Docomo communication system.

Mobal is one of the companies that people can use while in Japan. There are different types of data plans available for people to use, separated into two sections: long trips and short trips.

As for what the SIM card offers, these packages will vary depending on how much they cost and how much time people are staying in Japan.

• Prices are accessible for most travelers.
• Delivery service takes longer than expected.

Can I buy a SIM card at a Japanese airport?

For people traveling abroad, it’s important for them to know where they can get a SIM card to stay connected. In this case, let’s talk a bit about how to get a SIM card at a Japanese airport, which is important for everyone to know.

For travelers, the Haneda, Osaka, and Narita airports are great places to get a SIM card from a local mobile carrier. By having this in mind, remember that the requirements to get a SIM card from any of these carriers might be different from your local carriers. Among the cons, this is the one for travelers to think the most about.

Other cons could be how limited the service is or how expensive it can be, so keep that in mind as well.

As for the pros, if you decide to wait until you get there, the good news is that you will get different options to choose from directly at the airport. There will be different data plans available for use, and you will get to use the local data networks too.

But overall, yes. Travelers have the chance to get a SIM card while traveling to Japan, but it will be a bit more complicated.

How much data do I need for 2 weeks in Japan?

In most cases, 2 to 5 GBs of mobile data will do for those two weeks, but keep in mind this might limit you a bit on what apps you can use.

To have more freedom, travelers should get a virtual SIM card that allows them to have at least 10GB of mobile data.

What is the Best SIM card for Japan?

Is it better to get a SIM card or Pocket WiFi in Japan?

SIM cards, eSIM, and Pocket WiFi in Japan are all viable options. Pocket WiFi devices for Japan might be a great option for travelers, but these are known for being more expensive than other alternatives available in the market. For example, a week of use with a Pocket WiFi can easily cost more than $70, depending on the company travelers are using.

On the other hand, a SIM card is a better option. And a virtual SIM card is even better to use in Japan. These are cheaper, easier to get, and offer way more data than a Pocket WiFi could offer.
