About docomo
NTT docomo is a Japanese mobile network operator and part of the NTT group. It runs its own 4G LTE and 5G networks across Japan.
When plans on docomo fit your trip
- You want a Japan plan that names its network before you pay, and docomo is one you know.
- You are not tied to one network: these plans list KDDI and docomo, and your phone can join either.
- You need mobile data for maps, messages and train times rather than a Japanese phone number.
Mobile networks in Japan
The networks in Japan include NTT docomo, SoftBank, KDDI au and Rakuten Mobile. Our Japan plans run on the networks below, and every plan card names its network before you pay.
Check your phone first
Your phone needs to support eSIM and be unlocked for other networks. A phone sold for another market may not cover every band docomo uses, so check your exact model before you buy.
More for your Japan trip


A few things before you fly.
What is docomo?
NTT docomo is one of Japan’s mobile network operators, part of the NTT group. A docomo eSIM here means a prepaid travel data plan whose card lists docomo as a network it uses in Japan.
Will my phone use docomo or KDDI?
These plans list KDDI / Docomo as their network, so they can connect through either. Leave network selection on automatic and your phone joins one of the two; the plan card does not promise a particular one.
Do docomo plans include 5G?
docomo runs a 5G network in Japan, but our plan cards do not mention 5G, so we do not promise it. Plan around the data allowance and the days on the card.
