History
Kōshiyama Station opened on 8 August 1940 when Japanese Government Railways extended the Kisei-Nishi Line southward from Shingū toward Kii-Kimoto (now Kumano-shi) and added the station as an intermediate stop. The line was renamed the Kisei Main Line on 15 July 1959 following a nationwide route consolidation. Freight handling was discontinued in 1973, and the station has been unattended since December 1983. With the privatisation of Japanese National Railways on 1 April 1987, operation passed to JR Central, which continues to manage the station remotely from Kumano-shi Station.

Notes
The wooden, hip-and-gable station building from 1940 still stands; passengers waiting inside can still see the shuttered ticket window and parcel counter preserved from when Kōshiyama was a staffed station.
