Excellent service, product was great!

Used a doccomo Wi-Fi router for a week long trip in Hokkaido. Product worked great! The extra battery was very helpful too for really long days when I couldn't recharge the router.

Can't do without it.

Went to Kyoto, Hakone and Tokyo, simply awesome. Wifi made finding places easy. Will use it again without second thoughts. Thanks.

Great Price & Works Very Well

Very easy to book online and the price was just right. The Silver JapanWifiBuddy was waiting for us when we checked in at our hotel as arranged. Connection was very easy and the battery life FANTASTIC. Used it all day on a single charge and still going strong late into the evening. Thanks for a great product and making it all so easy.
