History
Ariigawa Station opened on 1 October 1970 as Higashi-Ōgata Station, when Japanese National Railways extended its Nakamura Line southwards from Tosa-Saga to Nakamura. It was renamed Ariigawa Station on 15 November 1982. Following the 1987 breakup of JNR the unstaffed station briefly belonged to JR Shikoku, then transferred on 1 April 1988 to the third-sector Tosa Kuroshio Railway when the Nakamura Line was spun off. The station occupies an embankment above farmland in Kuroshio, Kōchi Prefecture, with a single side platform reached only by a footpath and steps; only local trains stop there.
Notes
There is no access road; the only way onto the platform is a paved footpath ending in a flight of steps up the embankment.
