For years, people have asked me which SIM card to get in Japan, and for years, I’ve mumbled something about pocket WiFi and changed the subject. The truth is Japan has 98.1% 5G coverage and the highest 5G Mobile Trust Score in the G7, meaning you should have internet so fast it feels like cheating.

However, last year after several friends arrived in Tokyo, bought SIMs, and somehow had worse reception than a potato with an antenna taped to it, I discovered overseas travelers aren’t necessarily enjoying the same reliable, high speed internet as folks living in Japan. It turns out, many SIM providers piggyback off weaker networks.

So, we did the sensible thing—we built our own. Journey Japan eSIM runs on NTT Docomo, largest and most reliable network.
I then ventured out to painstakingly test it across the country—from Hokkaido’s frozen tundra to Kyoto’s quiet backstreets and Okinawa’s sun-kissed beaches and not once did it let me down (well, except maybe once in a cave).

So now, at last, I finally have a SIM I can recommend.
Our own. Journey Japan eSIM—because fighting for WiFi in a café shouldn’t be part of your itinerary. Happy travels guys! And drop us a line to let us know how you get on at support@jjesim.com!
