History
Inariyama-kōen Station opened on 1 April 1933 on the Seibu Ikebukuro Line at Inariyama 1-chōme, Sayama, Saitama Prefecture; initially the layout consisted of a single side platform. On 13 November 1968, when the Musashi-Fujisawa–Iruma-shi section was double-tracked, the station was rebuilt with two opposed side platforms and two tracks. The current station building and footbridge entered service on 21 March 1988. Network-wide station numbering on 17 March 2012 made it SI22, and through-running services to Yokohama and Motomachi-Chūkagai via the Tōkyū Tōyoko Line started on 16 March 2013. From 1 April 2024 the station went over to remote intercom-assisted operation and ended on-site ticket sales.

Notes
Although the rail line is older, the adjacent Iruma Air Base only grew up around it after 1938; today the trains pass directly through the base, and a temporary platform-end ticket gate is opened on 3 November each year for the base's annual air-show crowds.
