Easy to buy, easy to activate, great coverage, nothing to complain about. Will use it again next time in Japan. I was travelling in Tokyo, Kyoto, Osaka. So I can not commentate on coverage in other parts of the country.

Nemish Shah

I used japan wireless to get my eSIM .It was easy to install and get started with the instructions clearly mentioned on the website.Also they have a kiosk at the Haneda airport so in case you get stuck the people will help you out.

Jose Colucci Junior

I bought it while I was in the US and activated it as soon as I arrived in Osaka. It started to work immediately. I’ve been using it for two weeks now and am not even close to 10 GB.

PAUL KAWAHAKUI, JR.

As I have always done for more than a dozen orders, the package with the unit was waiting for me at the hotel upon check in. The process is extremely simple including returning the unit; and I've never encountered any problems with the rentals. Will be doing this again in November 2025.
