Edogawa (江戸川区, Edogawa-ku) is a special ward in the Tokyo Metropolis in Japan.
It takes its name from the Edo River that runs from north to south along the eastern edge of the ward.
Edogawa has a sister-city relationship with Gosford, New South Wales, Australia.
The Nishikasai [ja] area has a high concentration of Indian origin families.
Indian people settled in Nishikasai due to the proximity to the Tokyo Metro Tozai Line, which connects to their places of employment.
