Exactly what we wanted
Couldn't be happier with the service. Package was ready for pickup at the airport's post office booth when we got there. Got us connected for the entirety of our trip. The spare battery came in handy too being out long hours most days. And returning everything was a simple task of putting the equipment into the included return envelope and dropping it off at the post office before our flight. Thank you so much!

Excellent whilst travelling
We rented the Diamond Wifi Buddy - it had excellent signal whilst traveling throughout Japan. Customer service was brilliant and very helpful. Would highly recommend.

Amazing service-will use again!
Using Japan Wifi buddy was the best decision I made on our trip to Japan! Pick up from Haneda Airport was super easy as was posting back the equipment at the end of our trip. The Wifi device lasted all day with the included battery pack. Wifi service was impeccable and only dropped out once or twice in our three weeks in Japan. Would definitely recommend to everyone!

Last minute rental
Help desk was extremely helpful. I forgot to collect Changi wifi before immigration. There was no manpower from Changi wifi to bring the router for me. Customer service was poor, can’t speak well and not helpful at all. I managed to searched for japan wifi buddy. Really great service and wifi was delivered to their local post office in time. I was able to collect upon arrival. Router was great, good speed and return if the router was so easilybdinr. Thank you!
