Solid service, highly recommened
We went with the Diamond level which is up to 187.5mb/s and unlimited data. Obviously you get nowhere near 187mb/s, but that's just the theoretical max so we weren't expecting that. The couple of times I tested the speed we got 51mb/s download and 25mb/s upload so plenty fast enough for browsing, skype/facetime, using maps, uploading photos etc. Faster than my home internet in fact! We travelled from Tokyo to Hakone, Kyoto, Hiroshima and Miyajima and always had good signal. The only place we lost signal was inside Sunshine City in Tokyo but had no issues inside other malls/buildings. In the end we used about 38gb of data over 16 days and had no issues with daily, 3 day or overall limits, it seems it really is unlimited. One thing to bare in mind is the battery drains really fast if you have your phone set to sync photos to the cloud. We turned this off and did it at night when it was charging. Another thing, if you're considering getting any type of poketwifi or just relying on hotel and free wifi, while it might exist, the few times I tried our hotel wifi it was incredibly congested to the point you could barely load a page. So we're really glad we had our own wifi and didn't need to rely on free/hotel wifi. The whole process from ordering, picking up at airport, using and returning was very easy, would definitely use the service again.

Happy Traveller
I was very happy with my pocket Wifi from Japan Wifi Buddy. But we couldn't get the battery pack to work - not sure if I was doing something wrong or not. And the Buddy didn't work when plugged into DC (power point or car USB port), which was somewhat frustrating one day, until we worked out what was happening. Hiring pocket Wifi is a necessity when travelling overseas.

Best experience
Our trip would have been a nightmare without the pocket wifi, having the backup battery, clear instructions and return envelope was a dream. It also arrived at our hotel earlier than we expected which was very handy, 10/10 I recommend it and will use again.
