The station consists of a single island platform serving two tracks, connected to the station building by a level crossing. The station is staffed, and the second story of the station building contains the offices of the Akita Nairiku Jūkan Railway.[citation needed]
Aniai 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.[1]
