In the past there hasn't been a lot of convenient free wifi access for travellers in Japan. It also isn't that easy getting mobile data sim cards or portable wifi. This makes things a whole lot easier and will hopefully be useful for all those Ozbargainers who have taken advantage of the cheap airfares.
Japan Connected-free Wi-Fi is an application that makes it possible to connect to Wi-Fi networks easily at approximately 16,000 access points located at Narita Airport, Haneda Airport, major JR East railway stations, Seven-Eleven stores and elsewhere. The app is free to download, and it is also completely free to connect to Wi-Fi networks in the service areas.
Sugoi :D
