History
Hachimanyama Station opened on 1 May 1918 as Matsuzawa Station, slightly to the Shinjuku side of its current site. It was renamed Hachimanyama on 1 September 1937 to honour a nearby Hachiman shrine. Wartime mergers moved the station through Tokyu in May 1944 and into the spun-off Keio Teito Electric Railway in June 1948. Elevation work tied to the new Ring Route 8 highway began in July 1968 and finished on 10 July 1970, after which platforms evolved through several layouts to reach the present island-and-pass arrangement; the now-disused outer Up-side platform was demolished in August 2001. Rapid services began calling here on 27 March 2001.

Notes
Although the station bears the name of a Setagaya neighbourhood called Hachimanyama, the platforms themselves sit in the southernmost reach of Suginami ward, with the boundary running through the station precinct.
