Would use again 100%
I heard about the wifibuddy on reddit, and turns out it was a great recommendation. As a non Japanese speaker, it was extremely helpful to communicate to others, use GPS and send snapchats. I didn’t work the greatest while in Niseko, but it does say its not too strong in some rural areas, as I was surrounded by mountains in Niseko.I will definitely rent this again on my return to Japan.

Surpassed expectations, would use again. (Platinum Plus)
I learned about WifiBuddy on Reddit and ordered the device on short-notice about 2 days before I arrived in Japan. I even made a mistake when ordering the device, and the WifiBuddy team reached out within 12 hours directly to help me fix the problem and have it shipped to the correct hotel. I used the device excessively throughout my entire trip, frequently sending photos through iMessage and constantly running the GPS. I didn't run out of data and the speeds were pretty surprising. This device is a necessity as a traveler, and especially for a non-Japanese speaker. Will use again when I return to Japan!

Great service
We thoroughly enjoyed using the wifi buddy. Thank you for the service and I will use it again when I come to Japan. We posted the wifi buddy and other things back from the post box at the airport. Thank you again.
