The station is served by JR Shikoku's Dosan Line and is located 163.4 km from the beginning of the line at Tadotsu.[3][4]
Layout
The station consists of two opposed side platforms serving two tracks. A station building linked to platform 1 serves as a waiting room. Access to platform 2 across the tracks is by means of ramps and a level crossing.[2][5] On the other side of platform 1, a siding leads to a freight platform which is used for the loading of sleepers and ballast for track maintenance.[6] The station is unstaffed but a shop sells tickets as a kan'i itaku agent.[7][8]
The station opened on 30 March 1924 when the then Kōchi Line (later renamed the Dosan Line) was constructed from Susaki to Kusaka. At this time the station was operated by Japanese Government Railways, later becoming Japanese National Railways (JNR). With the privatization of JNR on 1 April 1987, control of the station passed to JR Shikoku.[3][9]
