Wonderful experience
Came by Japan Wi-Fi buddy by chance and it was much cheaper than all of the options I had looked at. This scared me as the lowest price usually means worst service and quality. I was wrong to think this about Japan Wi-Fi buddy. It was waiting at my hostel when I arrived and everything worked perfectly. I got about 98% coverage with the 2% being lost coverage on train rides in the middle of nowhere and really only for a few Mins. It was kinda sad returning it at the airport post-office as I had become so close with my little wifi buddy after the two weeks lol

Perfect wifi solution, absolutely essential in Japan
No issues whatsoever. Easy pickup at Narita T2, just as good dropoff in letterbox at T2. Great wifi no issues with speed. Consider it a must have for travelling in Japan

Incredible Service
I absolutely loved my experience with Japan WifiBuddy. I picked it up at the airport as soon as I arrived and was easily online and posting Instagram stories before I was even on the Narita express. I spent ten days in country and the WiFi buddy was flawless. Significantly better service and download speeds than I get in the US with my normal carrier. Highest of recommendations. Will definitely be using again on my next trip to Japan.

So useful!
WifiBuddy made my trip to Japan way lot easier. Being able to access the Internet at any time was extremely useful. I also loved the fact that you can pick it up and drop off at the airport, so you are connected from the moment you arrive to Japan until you leave the country. I strongly recommend it! Battery runs off quickly, though. They give you an extra charger, but I'd take another one.
