Hamadayama

No publicly available departure data for this station.

Hamadayama Station sits on the Keio Inokashira Line in Suginami ward, Tokyo, 7.5 km from the Shibuya terminus and numbered IN11. It opened on 1 August 1933 as a Teito Electric Railway stop, was folded into Odakyū in May 1940, joined the wartime Tōkyū combine in 1942, then passed to the newly separated Keio Teito Electric Railway on 1 June 1948. Only all-stations local services stop here. The station was rebuilt in 1995–96, moving the station building underground and lengthening the platform to accept the new 20-metre, five-car Keio 1000 series trains, and eliminating an in-station road crossing in the process. Station number IN11 was introduced on 22 February 2013 and platform doors entered service on 6 December 2025.

The station has only a north-side exit; reaching the platform from the south requires crossing what locals call the "unopenable" Kichijōji-end pedestrian crossing, and Suginami's planned south-side concourse project was suspended in January 2023 after lease talks with the landowner stalled.
