I have rented a pocket wifi from Japan wireless 3 times in the last 5 years covering Southern Japan, Hokkaido, and Central Japan (Osaka/Kyoto through Nagano and Tokyo. Device worked great in all regions. Very easy to set up, use, and return. Battery life was good.

The product that I used was excellent and very easy to set up

Excellent coverage and easy to deal with had it delivered to my hotel was there waiting for me when I arrived

The picket wifi worked just as advertised as has a great battery life

so great.,a lifesaver for sure. Like your own private helicopter.

Used in Tokyo and Kyoto. Worked great for us. Easy pick up (mailed to hotel) and drop off (mailbox at Kansai Airport).

the service was perfect. no problems. Absolutely recommended

I wouldn't have survived in Japan for 2 weeks if I did not have this service. It was great, cheap, and easy to pick up and return.

Our visit to Japan was enhanced with the portable wifi.
The unit from Japan Wifeless was compact

Everything worked great and easy to follow instructions
