Route map Dosan Line

Dosan Line (土讃線, Dosan-sen^?) is a railway line in Shikoku, Japan, operated by the Shikoku Railway Company (JR Shikoku). It runs between Tadotsu Station in Tadotsu, Kagawa and Kubokawa Station in Shimanto, Kōchi. The line links the city of Kōchi with northern Shikoku and the island of Honshū via the Seto-Ōhashi Line. The first section of the line between Tadotsu and Kotohira opened in 1889; the whole line was completed in 1951. The name of the line comes from "Tosa" (土佐^?) and "Sanuki" (讃岐^?), the old provincial names of present-day Kōchi Prefecture and Kagawa Prefecture, respectively.
