Great for staying connected on the go
I got the Platinum option I've been quite satisfied so far (been using it for a bit over a month). The device is very small (about the size of a smart phone) so it's very convenient to carry around everywhere, thus helping you stay online all the time - and trust me, you will need access to Google Maps and Google Translate a lot, especially if you don't speak Japanese! The battery usually lasts me for almost the entire day and that's without the backup portable charger.
The downside might be that the achieved speeds are nowhere near the theoretical maximum speeds (JWB's website does warn you about it!). Even though the maximum speed for Platinum Wifi is 220 Mbps, I've never got much more than 1 Mbps. Still, this is more than enough for regular day-to-day use.
