The station consists of two opposed side platforms serving two tracks. A mock-Tudor style station building connected to platform 1 houses a waiting room and JR ticket window (without Midori no Madoguchi facilities). Access to platform 2 is by a footbridge.[2][5][6]
The station opened on 15 November 1924 as an intermediate stop when the then Kōchi Line (later renamed the Dosan Line) was extended eastwards from Kusaka to Kōchi. 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][7]
