History
Inokashira-kōen Station opened on 1 August 1933 as the terminus of Teito Electric Railway's initial Shibuya-to-here section, written then as "Inogashira-kōen". It became an intermediate stop on 1 April 1934 when the line was extended on to Kichijōji. On 1 May 1940 the operator merged with Odawara Express Railway, putting the station on Odakyū's Teito Line; Odakyū was in turn absorbed by Tokyo Express Electric Railway (the wartime "Greater Tōkyū") on 1 May 1942, and on 1 June 1948 Keiō Teito Electric Railway split off again, with the station passing to its Inokashira Line. The Japanese-script form of the name has shifted from "井之頭公園" to "井ノ頭公園" around 1950 and to today's "井の頭公園" around 1960. The station building was rebuilt in late December 1975 and refurbished in July 2006, adding a lift, accessible toilets and reworked staff facilities.

Notes
Inokashira-kōen lies just 600 metres from neighbouring Kichijōji and shares the Inokashira Park (Inokashira-onshi-kōen) catchment with it; on weekends during cherry-blossom season some Inokashira Line express trains make extra stops here.
