• Iwate Galaxy Railway Line: Ichinohe ⇄ Kotsunagi

Kozuya Station opened on 1 September 1891 as a station on the Nippon Railway Tōhoku Main Line in what is now Ichinohe Town in Iwate's Ninohe District. A turntable for steam locomotives operated here until Ichinohe Station opened. Nippon Railway was nationalised on 1 November 1906, bringing the station under the state-run system. Freight and parcel handling ended on 1 February 1984 and the station became unstaffed. JR East took over at the 1 April 1987 privatisation. When the Tōhoku Shinkansen was extended to Hachinohe on 1 December 2002 the parallel conventional segment was transferred to the third-sector IGR Iwate Galaxy Railway, and Kozuya became one of its stations. The wooden station building still stands and houses a JA farm-produce stand opened in 2004.

In 1926 a groundbreaking ceremony was held in front of the station for a planned Tōhoku Tetsudō Kōgyō mining railway to Kuzumaki and the Ogawa mine, but construction stalled amid the Depression and the line was never completed.
