Avis

You can nover go wrong with this! I always rent this when I'm in Japan. :D

All went really smoothly from pick-up to returning the package, and the wifi worked everywhere.

Worked very fine in many different locations in Japan.

We decided against mobile SIM card or e-sim, because this would've drained the battery too much when using it as hotspot the entire day. This solution was just perfect for us and we would do it again next time for sure.

All fine, great and very usefull

We had 3 weeks in Japan travelling between Hiroshima in the West to Tokyo in the East and including some remote areas along the Nakasendo.
After connecting in Osaka after arrival all worked well providing map access virtually everywhere.
We had a connection problem when moving from near Nagano to Tokyo but this was fixed very promptly by email.
Good system which I will use again.

It was a very good decision to rent this wireless router. It made navigating Osaka that easy. Will definitely go with this again when we go back to Japan.

The pickup and drop were seamless and the network coverage was efficient throughout the places I visited in Japan.

I always go with the Premium Wifi always great reception.

The modem was really good, and we were able to use till the end of the day, just a couple of time we ended to use the power bank. The speed of the WiFi was quite good (I didn't do any speed test).
I didn't give 5 stars, because we had some issue in the beginning (no internet connection, probably due to the provider and not related to the WiFi modem), and we lost some time in the airport.
