History
Koigakubo Station opened on 10 February 1955 on Seibu Railway's Kokubunji Line in what is now Tobukura, Kokubunji City, Tokyo. For its first three decades, transfers between platforms were made by an at-grade pedestrian crossing; this was replaced by a footbridge on 20 October 1986. Barrier-free works completed on 20 February 2006 added escalators and a lift to the footbridge, with the escalator on the Higashi-Murayama-side platform set permanently to up-only and the Kokubunji-side platform's escalator to down-only. Station numbering was introduced across the Seibu network in fiscal 2012, with Koigakubo assigned SK02. On 25 March 2025 the staffed ticket window closed and the station was reorganised as a remote-assistance station.

Notes
Koigakubo's evocative name ("hollow of love") has made it a recurring backdrop for popular fiction: Shinji Mizushima set the fictional Tokyo Mets ballpark Kokubunji Stadium here in his manga "Yakyū-kyō no Uta", and Tokuya Higashigawa's mystery novels "Koigakubo Gakuen Tantei-bu" centre on a high school just outside the station.
