I buy rental 2 weeks Softbank: High-Speed. Very successful experience. For 2 weeks I visited Tokyo, Kashiwa, Nagoya, Kyoto, Osaka, Hamamatsu, Shizuoka. Everywhere was an good connection, I used online maps and very quickly could find the place I needed. Also I sometimes upload photos. Not very fast, but quite acceptable speed, considering that the photos are large sizes. When I visit Japan again, I will turn to CDJapan.
