Commucle Map is an unofficial map for a bicycle rental system(community cycle) in Tokyo(Chiyoda ward, Minato ward, Koto ward, Chuo ward, Shinjuku ward, Bunkyo ward, Shinagawa ward, Ota ward, and Shibuya ward), Yokohama, Sendai, and Hiroshima. It's useful when you want to rent bicycle since it displays the position of you and port(bike rental / return location).
