Great Product and Service
The Wifi Buddy worked extremely well for our trip to japan. We traveled by train from Tokyo to Kyoto, to Osaka and Hiroshima and had zero issue with service at any of the cities or while on the train. Service was great as it was waiting for us at the airport. Would highly recommend this to any of our friends

Excellent Service!
I booked the Diamond Pocket WiFi plus a separate SIM card so that both my wife and I would always be connected. As others posted here, the Pocket Wifi comes with a charger, a battery bank, and cables, so it's actually a considerable amount of stuff! The overall setup worked really well - the packet was ready for pickup when we arrived and returning it was really easy as well (just dropping the pre-filled envelope into a mailbox at Narita). The connectivity was mostly excellent - though the device did get quite warm during the day (we're there in early March and it was quite cold, not sure if this would be a problem in summer). Also, the battery typically lasted for about 10 hours, so you either bring the spare battery pack or you stop for recharging during the day. Overall a really good choice, would do the same thing again for my next Japan trip!
