Okachimachi Station is served by the circular Yamanote Line and also the Keihin-Tohoku Line. Although not physically connected, Naka-Okachimachi on the Tokyo Metro Hibiya Line, Ueno-hirokōji on the Tokyo Metro Ginza Line, and Ueno-okachimachi on the Toei Oedo Line are within walking distance of Okachimachi and marked as interchanges on route maps.
The station is on a raised viaduct running in a roughly north-south direction. There are two exits, the north exit (北口?) and south exit (南口?). Both exits have ticket vending machines and toilets; however, the north exit has a Midori no Madoguchi staffed ticket office and escalators to the platforms. Luggage lockers are available at the south exit.
The station has two island platforms with two tracks on either side of each platform. Platforms 1 and 4 (the outermost tracks) serve the Keihin-Tohoku Line, while platforms 2 and 3 (the inner tracks) are used for Yamanote Line trains. This platform arrangement allows for easy cross-platform interchanges so that passengers may transfer between lines in the same direction by walking across the platform. East of the platforms lie tracks belonging to the Tohoku Main Line formerly running to Tokyo Station but which are now used to stable trains terminating at Ueno Station.
