Great Wifi Access
We recently spent two weeks in Japan using the Diamond WifiBuddy option. The device was great, with the only complaint being that occasionally it needed to be turned on again for some reason. The extra power came in handy for both the wifi and our other devices :)

I recommend!
I rented it to use by myself and the connection was good and the battery lasted all day! I'm a quite light user but there were days I had to make skype calls and I never had any problems. Pick up and return was also very simple. Overall a great experience especially as the price is lower than other wifi rentals I checked.

Reliable and great coverage!
My 29 days in Japan was made easier with the Diamond WifiBuddy. It arrived at my hotel on time and had everything in the package I needed for a long trip. The Wifi was reliable, strong and fast. It worked with all my apps and made using the Japan transport system easier. Returning the Wifi was a simple process. I'd recommend Japan WifiBuddy for any trip to Japan.
