History
Seibu-Tachikawa Station opened on 15 May 1968 on the Seibu Haijima Line, 11.6 km from the Kodaira terminus and roughly 5 km from JR East's Tachikawa Station in central Tachikawa, Tokyo. An overhead footbridge replaced the in-station level crossing on 30 July 1988. A new bridge-style station building and a north-south free passage entered service on 30 March 2011, opening the previously single-entry station to access from the north for the first time. Staffing was switched to a remote-assistance model with intercom-based support on 25 March 2025, and on-site ticket-window sales ended the same day. Station numbering assigned SS35 in fiscal 2012.

Notes
Despite its name, the station sits roughly 5 km from JR East's Tachikawa Station, and a portion of the south-exit rotary actually crosses into Akishima City.
