Saved our butts
Highly recommend using this product. Fast internet, stable connection, good battery and easy as pie to use. This product made our stay in Japan a breeze and it was much more affordable than any other option.

Great WiFi connection at an affordable price
I got the 6 GB a day plan and that was more than enough data for my boyfriend and I in Japan. The connection was great, we had service everywhere (Tokyo, Kyoto, Osaka, and Miyajima) except the mountainous areas near Hakone. In most cases, the connection was better than hotel WiFi, so we actually stuck to the WiFi egg most of the time. I compared prices with a few competitors, and this was the best! Also, the delivery process was easy! The package was at my hotel, ready for me when I arrived and when I leaving Japan, the hotel reception was able to take care of sending it through the mail.

Luke Elliot - WifiBuddy worked great for our particular need
This was exactly what we needed. Two workers from Canada who really needed Internet access in our cabins in order to keep up with their work back in Canada while they served at the Aomori Christian Center. It worked great for them. They were a little concerned when a message came up on their screens saying something like "you have used 96mbs out of your 100mbs" but I understand that there is something in the instructions that actually addresses that issue and explains that the service is limitless in spite of that message.
