Tosa-Irino Station opened on 1 October 1970 as Japanese National Railways extended its Nakamura Line through Kuroshio, Kōchi Prefecture. After the breakup of JNR in 1987 the station briefly belonged to JR Shikoku, then transferred on 1 April 1988 to the third-sector Tosa Kuroshio Railway when the line was spun off. Simple agency-style ticketing was discontinued on 1 April 2004, leaving the station fully unstaffed. The lodge-style building houses a waiting area, ticket vending machines, a cafe and a convenience store, and all limited-express services on the line — Shimanto and Ashizuri — call here.

All limited-express trains running between Kōchi/Takamatsu and Nakamura — both Ashizuri and Shimanto — stop at this otherwise unstaffed rural station.
