Reliable, easy to use, plenty of data!
This little wifi device made our trip SO much easier. Navigating without Google Maps would have made the whole holiday impossible but we were able to navigate, post on social media, check emails, etc. The device is simple to operate and charges quickly. An absolute life saver!

Japan wifi buddy
Best decision I made before going to japan. I used the maps function each day to get me around on my own. I wouldn’t have enjoyed my stay as much if I didn’t have this service.

Don’t travel to Japan without it!
Love this device - worked so well and was a lifesaver in so many ways - was able to find our way around Japan - maps, translate etc etc...

Perfect and Worth Every Penny
Could not be happier than going with my choice of the Diamond WifiBuddy from JapanWifiBuddy.com. The whole process was simple and worked perfectly. The support team started by making sure all of my information was correct to ensure a no-hassle delivery pickup at the Narita Airport. I got email tracking confirmation when it was shipped. The instructions they provide for pickup including a map made it a breeze. The package came with a portable charger and carrying case and pre-filled out return envelope. We had excellent coverage all throughout Japan on our 16 day trip from Tokyo, to Kyoto, Hiroshima, and Mt Fuji.There was never a hiccup in service and it even beat out the hotel wifi most of the time plus having a secure wifi connection on nights I had to work made it all the better. Cannot recommend JapanWifiBuddy enough!
