Tosaden Kōtsū Sanbashi Line

The Sanbashi Line (桟橋線) is a tram line serving the city of Kōchi, Kōchi Prefecture, on the island of Shikoku, Japan. The 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).

From its establishment up until September 30, 2014, it was operated by Tosa Electric Railway (土佐電気鉄道), but from October 1, 2014, the newly formed Tosaden Kōtsū company took over operation.

Stations
The line has 11 stations.
