History
Komazawa-daigaku Station opened on 7 April 1977 at the site of the former Tokyu Tamagawa tramway's Manaka stop, as a station on the New Tamagawa Line of Tokyu Corporation. It is located in Setagaya, Tokyo. The station is named for nearby Komazawa University, after a protracted dispute over its location: the original 1968 plan placed the station near the existing Komazawa tram stop, closer to the university, but the 1969 revision moved it about 500 m east to the present site near the former Manaka stop, prompting an unsuccessful 1970 administrative lawsuit by local residents and the university. The New Tamagawa Line was merged into the Den-en-toshi Line on 6 August 2000. PASMO IC card use began on 18 March 2007, platform doors entered operation on 22 October 2017, and a station renewal completed on 13 April 2025 used aluminium alloy reclaimed from retired Tōkaidō Shinkansen N700 series cars for some interior fittings.

Notes
Per its connection with the nearby Komazawa Olympic Park, the station's official theme colour is "young leaf green", although the actual paint used is more saturated and noticeably greener than the JIS-standardised "young-leaf" hue.
