Fuji, Yokohama, Nagano, Nikko, Kusatsu, Tohoku, Hokkaido and Fukushima. Apart from that, before you arrive in Japan, how about downloading the NAVITIME for Japan Travel app on iOS or Android? This app will serve up an augmented reality mode which will depict a Street View-style image of the location whenever there is an available Wi-Fi hotspot. This free Wi-Fi access is good for two weeks.
