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

The station is on a raised viaduct running in a roughly north-south direction.

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.

[3] From 14 March 2015, rapid services on the Keihin-Tohoku Line began serving the station on weekends and national holidays only.

Particularly well-known is Ameya-Yokochō ("Ameyoko"), a busy shopping street dominated by small market-style stalls selling a wide variety of wares.
