Almost 100% up time with great speeds
Everything worked as expected with the Japan WifiBuddy. Pick up was as easy as going to the postal area of Haneda Airport and showing my passport and the included documentation. Setup was a breeze and speeds were good between two users and I had very little downtime (sometimes the WiFi would drop momentarily). Never did we notice any substantial drops in coverage even in some pretty remote places. Overall, I would completely recommend the Japan WifiBuddy Diamond package to anyone visiting Japan.

Portable WiFi Worked Across Many Cities in Japan
Fast internet access with great coverage, even in more rural areas. Worked in both Kanto and Kansai regions (Tokyo, Osaka, Kyoto, Mt. Fuji, Nara and Nikko). Convenient pickup from Narita Airport and hassle-free return!

Great! Would recommend.
Very convenient and easy to use. Picking it up in the airport was nice and easy. Mailing it back was nice and straight forward as well. Great experience, would recommend!
