Must have
We booked our Wifi Buddy for 3 weeks. It was waiting for us at the airport charged and ready to go. We used it non-stop our entire trip it was our lifeline (did not get a sim card) and we were completely satisfied. We had reception almost everywhere and the battery charger helped to make the Wifi last all day! 10/10 would recommend to anyone going to Japan!

Amazing WiFi and service
WiFi buddy was an absolute crucial part of our 2 week stay in Japan. Pickup at the airport post office was painless. The internet was extremely reliable and fast, battery life was amazing, especially with the included backup battery. With the backup we could be out all day (12 hours) and not worry about losing connection. The included wall plug for charging with 2 USB ports also made it easy to keep everything charged, including our own electronics. Included return mailer seas this sea as the best in Japan.

Amazing
The WifiBuddy was fast and reliable for me and my wife during our trip. We traveled between Tokyo, Osaka, Kyoto, and Nara and the whole trip the WifiBuddy performed even better than expected. Would always recommend them, and will always use them for my trips!
