History
Ugo-Ōta Station opened on 1 November 1970 as a station on the Japanese National Railways Kakunodate Line, serving what was then the town of Tazawako in Akita Prefecture. The line was converted to third-sector operation on 1 November 1986 and incorporated into the Akita Nairiku Jūkan Railway's Akita Nairiku Line. The station has remained a small unstaffed halt with a single side platform and a shelter in place of a station building, served only by the regional Nairiku Line that runs roughly 90 km from Takanosu in the north to Kakunodate in the south.
