diamond wi fi buddy
This was a fabulous service and the wi fi was excellent it made our trip much easier and having the charger included was an unexpected bonus. Wi fi was delivered to our hotel and we posted it back at the end of our holiday. An efficient excellent service.

Good Experience with Japan WifiBuddy
Had a Good Experience with Japan WifiBuddy when I was i Japan for 2 weeks, it was easy to pick up the package at the post office at Narita Airport. We also got a preadressed return package to send the unit back with, we packed it and delivered it to our hotell staff when we left after 2 weeks. The unit itself worked flawlessy and we got a powerpack with it for long days out in the city. All in all a great service, would use them again for my next visit to Japan.

Worked great most of the time
We were happy with the WiFi buddy. It was far faster than the hitel’s free WiFi and was a huge help to navigate Japan’s cities and transit systems. I wish the battery life was better.

Reliable and worth it!
This is my second time using Japan WiFi Buddy, I often visit Japan and I have found that this company are reliable, fast and are always there if you need help. I have travelled all around Japan and found that the signal stays strong wherever I am, whether its in the city or more rural areas. The extra battery pack was a real life saver. The only thing is that the device can get a little hot, however I was using it during Japan's heatwave but I still had no real issues other than the heat. I will definitely order again when I return to Japan. Thank you!
