The first section of the line, from Kobokawa to Tosa-Saga was opened by Japanese National Railways (JNR) on 18 December 1963, and operated using diesel trains, functioning as an extension of the Dosan Line.[1] The section from Tosa-Saga to Nakamura opened on 1 October 1970.[1]
Freight operations ceased in 1984, and from 1 April 1988, operation of the line was transferred to the Tosa Kuroshio Railway.[1] With the opening of the Tosa Kuroshio Railway Sukumo Line in October 1997, the maximum line speed was raised from 85 km/h to 110 km/h.[1]
