Ōmagari Station opened on 21 December 1904 as a Communications Ministry stop on the Ōu Hokusen serving the town of Ōmagari, Senboku County. The Obonai light railway, today's Tazawako Line, joined on 30 July 1921 and was nationalised the following year. Midori-no-Madoguchi opened on 29 March 1973 and freight and parcel handling ended on 1 November 1986. JR privatisation on 1 April 1987 placed the station in JR East's hands, and an 18 August 1996 reconstruction culminated in the present Edward Suzuki-designed bridge-style station building, which entered service on 20 July 1997. The Akita Shinkansen arrived on 22 March 1997, and its trains reverse direction at the station in a switchback. The station building won a 1998 Good Design Award, and the station was named one of the Top 100 Stations of Tōhoku in 2002.

Shinkansen platforms 11 and 12 switched their departure melody on 1 July 2017 to Yume no Sora, the opening number of the National Fireworks Competition held annually nearby.
