• Oito Line: Nechi ⇄ Hiraiwa

Kotaki Station opened on 24 December 1935 when the government-built Ōito Line's northern section was extended from Nechi, in what is now Itoigawa, Niigata Prefecture. The line through to Nakatsuchi opened on 15 August 1957, making Kotaki an intermediate stop. Freight handling ended in 1981 and parcel handling in 1984, and the station was destaffed on 1 April 1985. The station building dating from the 1935 opening still stands. Service was disrupted by the July 1995 floods that broke the line for over two years and again by the November 2014 Kamishiro Fault earthquake; the passing loop was removed in 2007, leaving a single side platform. The station passed to JR West at privatisation on 1 April 1987.

The waiting room in the 1935 station building, with its built-in bench seating, is still in use, and the remains of a water tower stand on the station grounds.
