Koyamatsu Station opened on 20 June 1960 as a stop on the Japanese National Railways Kihara Line in what is now Ōtaki, Isumi District, Chiba Prefecture, 18.2 kilometres from the line terminus at Ōhara. It passed to JR East at the 1 April 1987 privatisation, and on 24 March 1988 the route was transferred to the third-sector Isumi Railway and renamed the Isumi Line. The station has a single side platform with a three-sided shelter, no staff, and surroundings of scattered housing and rice paddies along the Isumi River.

The shelter was renovated in March 2022 into an "Instagrammable" waiting room for a Fuji TV special.
