Great service.
We were really happy with our recent visit to Japan renting the silver wifi buddy. Very easy it was waiting at our hotel when we arrived and we dropped it in the mailbox at the airport when we left, service was always great thank you :-)

A+ Service
The Platinum Wifi was perfect for our trip to Japan. Finding the post office in Narita was a little confusing, but once we found it, picking up the device was very easy. The device worked everywhere within Tokyo and Hakone, except for some really tall buildings/hotels, which usually had their own wifi anyway. The device usually lasted us about 3/4 of our day, so the external charger was quite useful to get us through the end of the day. I would highly recommend this device for anyone traveling within Tokyo and nearby. Thanks again!

Great service
My stay in Japan was so pleasant this time because of my portable wifi rented from Japan wifi buddy. Tre was very reliable to answer any questions I had and my rented wifi was so technically easy and reliable. Thanks, Tre!!

Saved me many times
I wouldn't have been able to find anything without the wifi. And with 6 people in our group, we wouldn't have been able to find each other. This Japan holiday season is the most crowded, and the wifi helped me with finding locations, communicating with family, and researching the trip -- saved me time and hassle. The drop off and delivery was excellent. Only issues were some places (like in the Daiba mall) where I got no service. The error messages on the wifi units were all in Japanese, so I couldn't figure out what was wrong. A little guidance there (emailed images) would have helped. The gold unit also had a hard time charging, taking most of the night to get a full charge.
