Layout
The station consists of a island platform with two tracks at grade. A side platform (Platform 1) adjacent to the station building was used by the now discontinued Yamano Line and is no longer in use. The station building is connected to the island platform by an overpass. The station building is a one-story concrete building. There is a waiting area and ticket gates inside the station building. It is a simple consignment station. There are no automatic ticket vending machines, and payment must be made on the train early in the morning and at night. An upright piano was installed in the waiting area on March 11, 2017 through a street piano project conducted by volunteers in Kagoshima Prefecture.[2][3]
The station was opened by Japanese Government Railways (JGR) on 5 September 1903 in conjunction with the extension of the Kagoshima Line from Yokogawa Station (currently Osumi Yokogawa Station) to this station. On 11 September 1921 the Yamano Light Rail Line opens from this station to Yamano. This is renamed the Yamano Line on 2 September 1922. Freight services were discontinued in 1982 and baggage handling from 1984. With the privatization of Japanese National Railways (JNR), the successor of JGR, on 1 April 1987, Nishi Kobayashi came under the control of JR Kyushu.[4][5][6] The Yamano Line was abolished on 1 February 1988.
