History
Masuzawa Station opened on 30 July 1915 as Utō Station on the Iwate Light Railway, a 762 mm narrow-gauge line running 65.4 km between Hanamaki and the now-defunct Sennintōge Station. It was renamed to its present name on 16 December 1924. The Iwate Light Railway was nationalised in 1936, becoming the Kamaishi Line, and the station was absorbed into the JR East network at the privatisation of the Japanese National Railways on 1 April 1987. The station has a single island platform connected to the station building by a level crossing, with no platform numbers, and is unattended.
