History
Ōkubo Station opened on 21 October 1902 as a Japanese National Railways (JNR) stop on the Ōu Main Line, serving the village of Ōkubo in Akita Prefecture, and a public telegraph office followed in December 1903. Freight handling was withdrawn on 15 October 1981 and parcels in February 1984, and the station was unstaffed and converted to a simple agency stop on 1 November 1986. JNR privatisation transferred operations to JR East on 1 April 1987, management responsibility moved from Oiwake to Tsuchizaki in April 2010, and the station building was rebuilt in late 2015 after temporary operations starting that September. From the 26 March 2016 timetable revision all rapid services on the line began stopping here.
