Hello! I’m PASOKUMA and I live in Japan.

This article has been written using ChatGPT and Google Translate. If you notice any inaccuracies or areas that are unclear, please let us know in the comments section.

Recently, the number of tourists visiting Japan has been rapidly increasing.


I’ve decided to travel to Japan, but now I’m wondering how I’ll use my mobile phone.

Exploring new cultures and landscapes is great, but a common concern when coming to Japan is dealing with mobile connectivity.

But have no fear. Here’s a handy solution that lets you adjust your connection even before your plane lands.

This is about using an eSIM (electronic SIM card), which eliminates the hassle of replacing a physical SIM card. With eSIM, you can seamlessly and comfortably use your mobile phone even in Japan.

In this article, we will explain in detail “What is eSIM?” and “eSIM that can be used in Japan,” so please read through to the end.


What is eSIM?

A SIM (Embedded SIM or eSIM) is essentially an electronic version of a SIM card. It’s a necessary component for staying connected, even in places without a Wi-Fi network, using devices such as smartphones and tablets. Without a SIM card, you won’t be able to access the internet.

There are two types of SIM cards: the traditional physical SIM card and the digital eSIM.

In my case, I use a physical SIM card for my communication needs in Japan, and I always keep it in my device to avoid misplacing it. That’s why, for my travel purposes, I’ve opted for an eSIM, which eliminates the need for constantly inserting and removing the card.


If you use a physical SIM card, you’ll need to replace it when you travel.

I chose an eSIM when traveling abroad because I didn’t want to risk losing my SIM card, which I used in my home country. It would be a big problem if I lost it.

Registering an eSIM is incredibly easy; you just need to scan a QR code, and you can even prepare it in your home country beforehand. Give it a try!

eSIM that can be used in Japan “airalo”

airalo is a company that sells eSIMs for travelers.

This is a service that sells prepaid lines from carriers in various countries including Japan.
Simply purchase an eSIM on airalo, activate it on your desired mobile phone or tablet, and you’re ready to use it.

The communication type is data communication only; phone calls and SMS cannot be used.

The expiration date starts counting from when the line is actually opened, not when the payment is made.


I really like it because I can connect it right after the plane lands!

Prices will be settled in United States (US) dollars.

In Japan, you will need to use either “softbank” or “KDDI” 4G line.

Both are Japan’s leading telecommunications carriers, and you can use them without any problems in terms of speed and quality.


I use chat, SNS, and Spotify and it’s comfortable!
