Perfect for traveling
We were visiting Japan for two weeks and wanted to have access to the internet to confirm train times and find restaurants, hours for for shrines and sites, etc. This service was a great solution. I reserved and paid for the device while still in the US, then got confirmation that it had been sent to Narita. It was super easy to pick it up at the airport post office; I just told them my name and showed them my confirmation number, and they had it to me in a minute. We had no issues with it during our trip, and were pleased that it came with an external battery so we could easily keep it charged. And we only used a fraction of the allotted 100GB of data, so really there is no need to be skimpy on internet use if you need it! We will definitely use the service for our future trips!

Excellent, simple service
Exceptional signal all across Japan (Honshu, Kyushu, Shikoku). Didn’t experience any throttling or data limit and we used it all day, every day.
