great product
This is our second time renting from Japan WifiBuddy. Would recommend this product. Reliable, good battery life and easy to use. Pick up at Airport is very convenient. Returning the product is very simple - self addressed/pre-paid envelope provided with the product.

Worked very well
Never lost coverage, even when we went out to the fox village. Only thing I'd do differently if I use this again is get a lower tier. I went with my brother and between the 2 of us we only used 28gb for the 2 weeks we were there.

Very easy
The silver buddy was just perfect for our trip. Internet vast enough for maps and looking up info on websites etc. Would recommend it to other users!

Onmisbaar in Japan
Zo bleven mijn vrouw en ik met onze tablets en smartphone steeds online. Gps-gebruik, trein en metroregelingen steeds te raadplegen. Sommige plaatsen minder bereikbaar (bijvb Naoshima)

Diamond WiFi Buddy
We used the WiFi buddy during our 9-day stay in Japan (Osaka-Tokyo) and it proved to be quite the lifesaver. Their service was reliable and they were very easy to correspond with! I had a few questions before and during my trip and they were happy to accommodate me. I definitely would use their services again when I return to Japan!
