History
Okusawa Station opened on 11 March 1923 in what is now the Okusawa district of Setagaya, Tōkyō. A north exit was added in 1935. Platform extension work to accept six-car Meguro Line trains ran from September 1999 to August 2000, and on 6 August 2000 the Mekama Line was split into the Meguro Line and the Tōkyū Tamagawa Line, with this station passing to the Meguro Line. From 2018 a multi-year reconstruction prepared the station for eight-car Tōkyū Shin-Yokohama Line through-services, adding an express passing track, a footbridge and elevators. The new north-side station building, retail block and footbridge entered service on 26 February 2022, and the passing siding followed on 12 March 2022. Okusawa is the only Meguro Line station in Setagaya and the southernmost station of the ward.
