Great service at a great price
Super easy to reserve, pick-up at Narita Post Office (2 minutes), turn on and go. Easily connected 2 phones, iPad, and laptop, with seamless connectivity from Tokyo to Fukuoka. Router made it through every day without additional charging, Easy drop-off and done.Would definitely use again.

Awesome Service!
So happy that we used Japan WiFi Buddy for our recent trip to Japan. It was incredibly useful and worked flawlessly. Excellent connection speeds and not having to worry about limited bandwidth was very nice. I would definitely use this service again next time I am in Japan.

Easy, straightforward process.
There were so many wifi companies to choose from when I did my original research. Based on reviews on various websites, I felt Japan WifiBuddy would suit me best. I was not disappointed. Package was waiting for me in the airport - everything worked immediately and I always had a very strong internet connection throughout my trip. It made traveling around the country very easy. The external battery charger that came with it was a life saver.
