Ōnodai Station opened on 20 April 1965 as an unstaffed passenger halt on the Japanese National Railways Aniai Line, in what was then Aikawa Town in Akita's Kita-Akita District. The town of Aikawa paid the full 8-million-yen construction cost, making it a petitioned station. Local children had previously walked along the tracks to reach Aikawa-Higashi Elementary School in winter when farm roads became impassable, and a 1963 incident in which pupils threw stones at a passing steam locomotive drew official attention. Construction proceeded only after a planned welfare institution, Aiseien, was relocated to the Kanazawa hamlet near the station site. The Aniai Line was converted on 1 November 1986 to the third-sector Akita Nairiku Jukan Tetsudō, which operates the station today.

The station exists because Aikawa Town agreed to relocate the planned Aiseien welfare institution from the Kawai hamlet to the Kanazawa hamlet near the new station; Aiseien opened roughly six months after the station and has since grown into the 1,000-resident Ōnodai-no-Sato complex.
