Imaizumi Station opened on 15 November 1914 on the Nagai Light Railway in what is now the city of Nagai, Yamagata Prefecture. It became a junction with the opening of the Yonesaka Line's Yonezawa - Imaizumi section on 28 September 1926, and again with the extension toward Tenoko on 10 August 1931. The station passed to JR East at the privatisation of Japanese National Railways on 1 April 1987, and the Nagai Line was transferred to the Yamagata Railway on 25 October 1988, making Imaizumi a shared station of both operators. The two lines share roughly two kilometres of single track north of the station before separating at the former Shirakawa Signal Station, now within station limits.

Imaizumi is the only point where JR East and Yamagata Railway tracks are physically connected, so JR East's inspection cars travel via the Yonesaka Line platform here whenever they survey the Yamagata Railway's rails.
