History

The station opened on 21 October 1958, as a station on the Japanese National Railways. With the privatization of JNR on 1 April 1987, it came under the operational control of JR East. With the opening of the Tsugaru Kaikyō Line on 13 March 1988, operation of the station was shared between JR East and JR Hokkaido, and the station was regarded as the southern starting point of the Tsugaru Kaikyō Line for the determination of railway fares, although no trains of Kaikyō Line stopped at the station, and the effective southern terminus for all Tsugaru Kaikyō Line trains was at Aomori Station.
Services on the Tsugaru Kaikyō ceased on 26 March 2016 when the Hokkaido Shinkansen opened and replaced regular passenger services connecting Aomori and Hakodate.
