History
Oyamadai Station opened on 1 April 1930 on the Meguro-Kamata Electric Railway's 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A waiting room and the first "Threadline" inset information displays on Tōkyū were installed in summer 2009; both were withdrawn in summer 2016 when platform doors were added. Wayfinding signage for Tōkyō City University's Setagaya campus was added in 2014.
