Excellent service and WiFi Coverage
Has no issue pickup from the post office at Narita airport. WiFi coverage is exceptional. Has no issue on bullet train from Tokyo to Kyoto, under tunnel, etc... will rent again next time I visit Japan.
Thank you

Convenient, fast, portable WiFi
Rented a diamond WiFi for 15 days and shared the device amongst 5 people. We never had our speed throttled and had coverage in most areas of Japan. We traveled to Tokyo, Nikko, Kyoto, Osaka, Fukuoka, Hakone, and back to Tokyo during our 2 week trip. The only place we didn't have coverage was while we were on a hike along Lake Chuzenji (in Nikko), but it was remote, so that was to be expected. Seamless pick up at the Japan Post counter in Narita and dropped off in the prepaid envelope before boarding my flight at Narita was great! Lastly, I will say that the pocket wifi device did lose its power fast, but that happened when all 5 of us were connected and constantly using wifi. The back up battery that they provided helped, but we also bought a larger capacity back up battery around with us to recharge while out and about.
