Kaminoyama-Onsen Station opened on 15 February 1901 as Kaminoyama Station, a general station on the state-built Ōu Nansen line when the route reached north from Akayu. Through-service to Yamagata followed on 11 April 1901, making it an intermediate stop, and the 12 October 1909 route-name decree placed it on the Ōu Main Line. It passed to JR East and JR Freight at the 1 April 1987 privatisation. Freight handling ended on 3 September 1991, and on 1 July 1992 the station was renamed to its present form and added to the timetable as a Yamagata Shinkansen stop when the Fukushima–Yamagata mini-shinkansen opened. The station building, modelled on Kaminoyama Castle, was selected in 2002 for the Hundred Stations of Tōhoku, and Suica IC service started on the Ōu Main Line on 16 March 2024.

The station building is styled after Kaminoyama Castle, and was chosen in 2002 for the Hundred Stations of Tōhoku list.
