• Tokyu Oimachi Line: Todoroki (Tokyo) ⇄ Kuhombutsu

Oyamadai Station opened on 1 April 1930 on the Ōimachi Line, with a single island platform serving two tracks. On 1 April 1964 the platforms were reconfigured as two opposed side platforms, the layout that survives today. The station, in the Tōdoroki district of Setagaya, Tōkyō, has a separate ticket gate for each direction so that paid-area transfer between the up- and down-line platforms is not possible. A waiting room was installed in summer 2009, and the first "Threadline" inset information displays on Tōkyū followed in the autumn of that year; the Threadline displays were withdrawn in summer 2016 when platform doors were added. Wayfinding signage for Tōkyō City University's Setagaya campus was added in 2014.

Oyamadai Station has the highest ridership of any Ōimachi Line station passed by express trains, making it one of the line's leading terminals among stations served only by local trains.
