eSIM Japan

Direct from Japan. Powered by KDDI, au. 

Travel across Japan with confidence, knowing you are connected by KDDI, au, one of the nation’s most trusted networks for speed and reliability.

Choose the plan that fits your journey, 12GB, 21GB or 30GB, both generous in size and fully usable for hotspot sharing. Perfect for families or small groups who prefer one dependable plan rather than several scattered ones. Saves money too. 

There are no daily limits. You decide how to use your data, whether it’s streaming a movie on a long train ride or keeping the children entertained after a day of sightseeing.

Tested up to 1132 Mbps on 5G, this connection delivers both speed and consistency. Independent studies by OpenSignal have confirmed what travelers already know: KDDI, au stands among the best networks in Japan, from the neon streets of Tokyo to the quiet mountain towns beyond.
