The Sapporo Municipal Subway (札幌市営地下鉄 Sapporo-shiei-chikatetsu) is a mostly-underground rubber-tyred metro system in Sapporo, Hokkaido, Japan. Operated by the Sapporo City Transportation Bureau, it is the only subway system on the island of Hokkaido.
The system consists of three lines: the green Namboku Line (North-South line), orange Tozai Line (East-West line), and blue Tōhō Line.
Ticket prices range from 200 yen to 360 yen, depending on the distance to travel.
All lines of the subway use rubber-tired trains that travel on two flat roll ways, guided by a single central rail. This system is unique among subways in Japan and the rest of the world.
