Ochanomizu Station opened on 31 December 1904 when the Kōbu Railway pushed its line from Iidamachi to a then-westerly site near today's Ochanomizu police box. Nationalisation in October 1906 transferred the station to the state, and on 1 July 1932 the Sōbu Main Line began through-running into the present-day site between Ochanomizu and Hijiri bridges, laid out directionally with the Chūō tracks on the outside and the Sōbu tracks on the inside and served by a new station building designed by Shigeru Itō in the International Style. The Teito Rapid Transit Authority opened the Marunouchi Line station on 20 January 1954. After a 1989 redesign competition was abandoned, JR East announced step-free works on 26 March 2010, lifting accessibility long deferred on the river-and-cliff-bound site.

After a 1989 open-call competition selected a three-storey design that would have housed an aquarium and an art museum above a colonnaded, arched concourse, the project was abandoned: JR East judged that the strong columns needed to carry the structure above could not be built without stopping trains, disbanded the team, and the plan lapsed; the 1932 structure stayed in service into the 21st century.
