Which mobile networks does MolaHop use in Japan?
MolaHop connects you to KDDI/au, NTT docomo, SoftBank and Rakuten Mobile — all four of Japan's major carriers, all with 5G. This ensures maximum coverage from Tokyo and Osaka to rural Hokkaido and Kyushu.
Does the eSIM work on the Shinkansen?
Yes. Japan's Shinkansen bullet train routes are very well covered. You'll have 4G/5G connectivity on most lines, including the Tokaido (Tokyo–Osaka–Hiroshima), Tohoku and Hokuriku routes. Brief drops may occur in tunnels.
Will I have data in rural areas like Kyoto's countryside, the Japanese Alps or remote onsen towns?
Japan has exceptional coverage even in rural areas. Small onsen towns, remote temples and mountain villages typically have 4G — Japan consistently ranks among the world's best for rural connectivity.

We offer a range of data plans for Japan — from short 1–3GB plans for weekend trips to larger 10–20GB plans for longer stays. All plans include high-speed 5G/4G where available.
