The device provided worked excellent during our stay in Japan. No issues and the connectivity was perfect. I would definitely use again when I return and would recommend others to use this as well.

Worked great for our 7 day trip. Very fast speeds and great signals everywhere, including the metro areas. Battery was a little weak and would require recharging almost everyday while out but came with a backup charger. Very easy to pick up and return via the mail at the airport. Highly recommend over a SIM card.

I was very satisfied with the speed and reliability. It even worked well while I was in the Northern Alps!

It's my second time using it and it's really great! Coverage is great - only in very remote areas we lost connection. And returning the device is as easy as it could be.

Unfortunately, this time the included powerbank had less juice than when i first used the service. Back then, in 2019, we were using the router from 5 AM until, like, 10 PM. But now i had to recharge it in afternoon or use my own powerbank. And it's not fun losing internet connection because router's battery ran out at a very inconvenient time.

On the other hand - opening hours of the pickup spot on Narita Airport are very convenient. We have arrived by a delayed flight and BARELY collected out JR Passes before their closing time, but we had zero reason to stress about Japan Wireless pickup. Thanks for that!

Every year I use the Premium Wifi of Japan Wireless, its perfect!

Used to travel in Japon . Lost without this little box effective everywhere and for any search.

Perfectly working and extremely useful! Would be great if the battery would last a bit longer ..but overall, great service and simple use

Poket molto comodo di piccole dimensioni, ottima durata della batteria,e prende ovunque

Highly recommended.
Efficient service.

Easy to use, convenient.
