Guide to using ESIM in Japan

For most travelers, Japan is a dream destination. But everything from the Tokyo subway to the quiet mountain temple often depends on one basic modern tool: a reliable internet connection. In a country that often signs only in Japanese, public transportation can be complicated, and many stores do not accept foreign credit cards, having stable mobile data is key to a smooth experience.

This is where ESIM comes from. Unlike traditional SIM cards or Pocket Wi-Fi devices, ESIM is built directly into a phone and can be activated digitally – without accessing the store or deleting the current SIM card. For travelers traveling to Japan, Holafly’s ESIM has become the go-to solution for fast, simple and unlimited data access.

What is ESIM?

ESIM (the short for “embedded SIM”) is the digital version of the SIM card. It connects your device to a mobile network like a physical SIM, but instead of plugging in the chip, you install it through a QR code or an application and activate it once you reach your destination. Since there is no physical card required, you don’t need to search for SIM card kiosks or patches using your phone’s SIM tray after landing.

This is especially useful in Japan, as buying a physics simulator may sometimes require a local address or language level. ESIM allows you to skip all the hassles.

Benefits of using ESIM in Japan

For travelers arriving in Japan, the advantages of using ESIM are obvious. You can even place it at the airport right on arrival and install ESIM before the airport starts it. This means you will be able to connect shortly after landing – no waiting, no pressure.

Although public Wi-Fi does exist in Japan, it is often restricted, may require Japanese registration, and is not always available where it is most needed. With ESIM, you can access uninterruptedly as long as you try to find your way through the Tokyo Metro or translate menus in the Country Soba Store.

Holafly’s ESIM also allows typing on most devices, so you can share 500 MB to 1GB per day with your friends or friends or family members you travel with – no separate plan required.

Tips for using ESIM in Japan
