The Tosa Kuroshio Tetsudo was established on 8 May 1986 for the purpose of resuming construction of the Sukumo and Asa lines, which had been planned by Japanese National Railways but abandoned. The company acquired a license to operate the Asa Line in January 1988, and commenced construction of the line, which opened on 1 July 2002.
