Edogawa (江戸川区,Edogawa-ku), literally "Estuary River", is a special ward located in Tokyo Metropolis, Japan. It takes its name from the Edo River that runs from north to south along the eastern edge of the ward. In English, it uses the name Edogawa City.
The ward was founded in 1937 with the merger of seven towns and villages in
Minami-Katsushika District: the towns of Koiwa and Komatsugawa, and the villages of Kasai, Matsue, Mizue, Shinozaki and Shikamoto.
