Tosaden Kōtsū Sanbashi Line

The Sanbashi Line (桟橋線, Sanbashi-sen) is a tram line serving the island of Shikoku, Japan, in the city of Kōchi, Kōchi Prefecture. This tram line is part of the Tosaden Kōtsū network.

The line name "Sanbashi Line" sometimes denotes only the section between Harimayabashi and Sanbashi-dōri-gochōme. In this case, the rest of the line, between Kōchi-Ekimae and Harimayabashi, is called the Ekimae Line (駅前線, Ekimae-sen).
