History
Ikenoue Station opened on 1 August 1933 as part of the Teito Electric Railway's predecessor to today's Keio Inokashira Line in Daizawa, Setagaya. The line was absorbed into Odakyu's network on 1 May 1940 and into the wartime Tokyu (Daito-kyu) on 1 May 1942, with the Inokashira Line passing to Keio Teito Electric Railway when the conglomerate was broken up on 1 June 1948. A footbridge station building was added in July 1967, and the 2006 station-improvement project brought lifts and barrier-free access. Station numbering as IN04 was introduced with the 22 February 2013 Keio rebranding. Platform-edge doors entered service on 22 June 2025.

Notes
Ikenoue is just 600 m from Shimo-kitazawa, close enough that the next station is visible from the platform end.
