Ochiai Station opened on 16 March 1966 on the Teito Rapid Transit Authority's Tōzai Line. The platforms sit underground beneath Waseda-dōri at the boundary between Shinjuku's Kami-Ochiai district and Nakano's Higashi-Nakano district, with entrances in both wards. After the TRTA's privatisation, Tokyo Metro took over operation on 1 April 2004. PASMO became usable on 18 March 2007. The Ochiai pedestrian underpass and Exit 2b opened on 1 April 2014, and station-departure jingles composed by Minoru Mukaiya — "A Day in the METRO" for Track 1 and "Beyond the Metropolis" for Track 2 — were introduced on 24 May 2015.

The station's name comes from the nearby confluence ("ochiai" in Japanese) of the Kanda and Myōshōji Rivers, and the white round benches installed during the late-1990s renovation are a one-off design not found at any other Tokyo Metro station.
