About Us

Stay Connected.
Explore Japan.

Your trip to Japan should be about the places you discover, the food you try, and the memories you make—not about finding Wi-Fi or figuring out how to stay connected.

That’s why we created JAPAN-ON-LINE eSIM: a simple way for travelers to get reliable mobile data in Japan.

Choose the plan that fits your trip, receive your eSIM by email, and install it before you leave home. Once you arrive in Japan, you can connect to a mobile network without having to buy a physical SIM or carry a separate pocket Wi-Fi device.

JAPAN-ON-LINE eSIM runs on the NTT Docomo network, providing reliable coverage across Japan. From the busy streets of Tokyo to the historic neighborhoods of Kyoto and the beaches of Okinawa, you can stay connected while you explore.

And there’s more than data. JAPAN-ON-LINE eSIM also gives you access to exclusive travel perks and discounts at selected stores across Japan.

Less time worrying about connectivity. More time experiencing Japan.
That’s the idea behind JAPAN-ON-LINE eSIM.
