high speed, unlimited data, good package, and good cost. I think this is the best choice for a trip to Japan.
But using Postbox to return it is something...... difficult for foreigners. So be careful to use the postbox, and read the email(return notification) before returning it.

We prebooked WiFi before arriving. Pick up was easy to find. Wifi unit worked fantastically throughout trip and was so easy to just post in a mailbox at the airport before we left. Will definitely use on next trip.

This was the 3rd time I rented this device for my stay in Japan. It always worked perfect, was delivered to my Hotel on time and there is basically no setup except for entering the WIFI-Key. Nothing more to say!

Amazing. It worked just as intended

Great service, delivered to hotel, worked right away. Coverage excellent from Toyko to Hokkaida. Compact size, good pricing, will rent again! Also confirming receipt after posted back at airport nice touch!

The Wi-Fi connection on all places that we have been in Tokyo and Mt. Fuji were amazing. Always ensure that the unit is always charged, as well as the backup charger. Great experience on this product and will surely rent this product again when we visit Tokyo on our next vacation.

The packet included a charger and a small power bank, I did not have to use the power bank even on our longest day out (16 hours). Signal remained strong even in the subways! Love this!

Great signal at all times. The pocket device lasted all day without a charge. Would highly recommend.

I would highly recommend this wifi. Strong connection wherever we go, and the battery life is fantastic.

The Japan Wireless WIFI had been tremendous with smooth and wide coverage even at snow mountain area. Highly recommended for traveler.
