History
Iwate-Kamigō Station opened on 18 April 1914 as Kamigō Station, initially a freight-only stop on the Iwate Light Railway, a 762 mm narrow-gauge line running 65.4 km between Hanamaki and the now-defunct Sennintōge Station. Passenger service began on 15 May 1914, and the station was renamed Iwate-Kamigō on 10 February 1916. The Iwate Light Railway was nationalised in August 1936 and became the Kamaishi Line. The station was absorbed into the JR East network at the privatisation of the Japanese National Railways on 1 April 1987. In 2022 the passing loop was removed, reducing the station to a single side platform with one track; it is unattended.
