eSIM vs. physical SIM card: which should you choose for your trip to Japan?

đŸ‡ŻđŸ‡” Traveling to Japan: how to stay connected?

Today, staying connected while traveling in Japan is essential: to use Google Maps, translate a menu, book a train or post photos on Instagram.

There are two main solutions available to you:

  • Buy a local physical SIM card .

  • Use a dematerialized eSIM , like those offered by Planjapon .

So, which one should you choose? Here’s the clear, straightforward comparison.


đŸ“Č What exactly is an eSIM?

eSIM (for embedded SIM ) is a virtual SIM card integrated directly into your smartphone. It is activated by scanning a QR code – no physical card, no plastic, no travel required .

With Planjapon , you receive your eSIM by email within seconds of purchase, and you can activate it upon arrival or even before.
