History
Nishi-Kokubunji Station opened on 1 April 1973 as Japanese National Railways inaugurated the orbital Musashino Line, with the new stop slotted into the Chūō Main Line cutting at right angles to provide the planned interchange. JNR had intended a two-island, four-track Chūō layout from the outset, but a holdout on the planned site forced opening with only two side platforms. The station passed to JR East at the 1987 nationwide breakup. Automatic ticket gates entered service on 28 July 1992, Suica was accepted from 18 November 2001, and the nonowa Nishi-Kokubunji retail concourse fully opened on 13 September 2012. The Midori no Madoguchi staffed window closed on 31 October 2021.
