History
Kokubunji Station opened on 11 April 1889 with the Kōbu Railway between Shinjuku and Tachikawa, soon followed by the Kawagoe Railway platforms (today's Seibu Kokubunji Line) on 21 December 1894 and the Tamako Railway (Seibu Tamako Line) on 6 April 1928. The Kōbu line was nationalised in 1906 and folded into the Chūō Main Line in 1909. JNR converted the JR side to two island platforms with an elevated concourse in a 1986–1988 rebuild, after which the Marui-anchored station building opened in 1989. The Shimogawara goods branch terminated here until its 1973 closure on the opening of the Musashino Line; the JR side later passed to JR East at the 1987 nationwide breakup.

Notes
The JR platforms' 2017 departure jingle is an arrangement of the children's song Densha-gokko by composer Kiyoshi Nobutoki, who spent much of his life in Kokubunji; the local shopping district petitioned the city to lobby JR East for the change.
