Okachimachi Station opened on 1 November 1925 in what is now Taito ward, central Tokyo, and is operated by East Japan Railway Company. The elevated station is served by the circular Yamanote Line and the Keihin-Tōhoku Line, with two island platforms providing cross-platform same-direction transfers between the two lines. Waist-high platform-edge doors were installed on the Yamanote Line platforms in March 2014 and brought into service from 10 May that year. From 14 March 2015 Keihin-Tōhoku Line Rapid services began stopping at Okachimachi on weekends and national holidays. Station numbering was introduced in 2016, with the station assigned JY04 on the Yamanote Line and JK29 on the Keihin-Tōhoku Line.

Although they share no physical concourse, Naka-Okachimachi on the Tokyo Metro Hibiya Line, Ueno-hirokōji on the Ginza Line and Ueno-okachimachi on the Toei Oedo Line are within walking distance and are marked as interchanges with Okachimachi on route maps.
