Okachimachi Station (御徒町駅, Okachimachi-eki) is a railway station in Taito, Tokyo, Japan, operated by East Japan Railway Company (JR East).

## Lines

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.

## Station layout

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.

### Platforms

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 of the Ueno-Tokyo Line. These are themselves built on former tracks of the Tohoku Main Line running to Tokyo Station, that had been used for stabling trains when construction of the Tohoku Shinkansen took over land near Kanda Station previously used by the Tohoku Main Line, forcing services to terminate at Ueno Station instead.
