Wifi, SIM cards and eSIMs in Japan

Japan has reliable mobile coverage almost everywhere, but staying connected as a tourist still takes a little planning. Here is the honest comparison of eSIM, SIM, pocket wifi and roaming.

eSIM is usually easiest

If your phone supports it, eSIM is the smoothest option. You can activate before landing and avoid airport counters entirely.

Physical SIMs still work well

If you need a physical SIM, major airports and electronics stores sell tourist data plans from well-known providers.

Pocket wifi is best for groups

Families and groups often save money by sharing a pocket wifi device instead of buying multiple SIM plans.

Frequently asked questions

Does Japan have free wifi?

Yes, but it is patchy. Do not rely on it as your only connection.
