Arakawa is a special ward in the Tokyo Metropolis in Japan. The ward takes its name from the Arakawa River, though the river does not run through or touch the ward. Its neighbors are the wards of Adachi, Kita, Bunkyo, Taito and Sumida. In English, the ward calls itself Arakawa City.

Special wards are a special form of municipalities in Japan under the 1947 Local Autonomy Law. They are city-level wards: primary subdivisions of a prefecture with municipal autonomy largely comparable to other forms of municipalities.
