Edogawa-ku

Edogawa-ku is a special ward in the easternmost part of Tokyo, Japan, covering roughly 50 square kilometers along the Edo River. The area consists mostly of residential neighborhoods with parks along waterways and small shopping streets around train stations.

The ward was formed in 1943 by merging seven towns and villages, including Koiwa, Komatsugawa, and Kasai. The region had been known during the Edo period for freshwater fish farming, especially goldfish breeding that continues since the 19th century.

The name derives from the Edogawa River, which flows along its eastern boundary and marks the border with Chiba Prefecture. Many residents use the riverbanks for weekend walks, bird watching, or picnics under cherry trees in spring.

Most areas are accessible by JR lines and metro stations, including Hirai and Koiwa on the Sobu Line and Kasai Rinkai Koen on the Keiyou Line. Many parks and riverbanks are flat and easy to navigate, while shops tend to cluster around train stations.

The ward houses the Tokyo Sea Life Park with a large tuna tank and penguin habitat, among the largest in the capital. The adjacent Kasai Rinkai Park stretches across a wide coastal area and offers one of the biggest public green spaces in Tokyo.
