History
Semi-Onsen Station opened on 1 November 1915 as Semi Station (瀬見駅), serving the Rikuu East Line in what is now the town of Mogami, Yamagata. Freight handling ended on 30 November 1971 and parcel handling on 7 March 1983, when the station became unstaffed under a simplified-contracted arrangement. The station passed to East Japan Railway Company (JR East) on 1 April 1987 with the privatisation of Japanese National Railways, and was renamed Semi-Onsen Station on 4 December 1999 in recognition of the nearby hot-spring town. The passing loop was removed later that month, and the present station building was rebuilt in September 2008.

Notes
The platform was once an island platform reached via a level crossing, but one of its tracks was removed in December 1999 — yet the level crossing remains, so passengers still cross a closed track bed to board.
