History
Koikawa Station began life on 30 September 1944 as the Koikawa Signal Stop (鯉川信号場) under Japanese National Railways and was upgraded to a full passenger station on 1 February 1950, serving what was then the town of Kado in Akita Prefecture. The station became unstaffed in October 1971, and in 1982 a small replacement structure built from a converted shipping container took over from the original building. JNR privatisation on 1 April 1987 placed the station under JR East, which completed a new station building in July 2007. Management of the stop was transferred from Hachirōgata to Tsuchizaki in April 2010 and then to Higashi-Noshiro in October 2015.

Notes
For roughly 25 years from 1982 the station building was a repurposed shipping container — a stop-gap measure between the original wooden structure and the present 2007 building.
