The station consists of one side platform serving a single bi-directional track.
Kobuchi Station opened on 25 September 1936 as a station on the Japanese Government Railways (JGR) Aniai Line, serving the town of Ani, Akita.
The JGR became the Japan National Railways (JNR) after World War II, and the line was extended to Hitachinai Station by 15 October 1963.
The line was privatized on 1 November 1986, becoming the Akita Nairiku Jūkan Railway.
