Consistent and Reliable
We stayed in Osaka and Tokyo, some of the most common tourist destinations, and the service was mostly consistent. The backup power sustained well for our 12 hour days. For 2.5 weeks, we didn't reach out limit, but were very conscious of our usage. Would recommend this for three+ users.

Best thing to do
Getting the wifibuddy absolutely made the trip that much easier and better. Having the steady network definitely helped keep us on track for the busy days we had. I would recommend getting this for anyone traveling.

Perfect!
We ordered the wifi buddy before we left the US for Japan, and we had it waiting for us at the hotel when we checked in. It was compact and contained everything needed for charging... Was super easy. It was a lifesaver! Navigating the train system is so much easier w/ Google, and the wifi buddy kept us connected no matter where we were. When the trip was over we popped it into the pre-addressed, postage paid envelope they provided us and brought it to the hotel lobby desk and they mailed it back for us. This one is a no-brainer... It's a must have on a trip to Japan.
