The Arakawa River (荒川, Arakawa) is a 173-kilometre (107 mi) long river that flows through Saitama Prefecture and Tokyo.[1] Its average flow in 2002 was 30m³/s.
It originates on Mount Kobushi in Saitama Prefecture, and empties into Tokyo Bay.[2] It has a total catchment area of 2,940 km2 (1,140 sq mi).
The river is one of Tokyo's major sources of tap water, and together with the Tone River, accounts for around 80% of Tokyo's water supply as of 2018.[3] The Okubo water purification plant takes water from the river.
History[]
Attempts to control flooding of the Arakawa River have been made since the area that is now Tokyo became the de facto capital of Japan during the Edo period. Following a major flood in 1910 that damaged a large part of central Tokyo, a 22-kilometre (14 mi) long drainage canal was constructed between 1911 and 1924. In 1996 an agreement was signed to make it a "sister river" of the Potomac River in the eastern United States.[2] This means that officials and volunteers from both river areas collaborate with each other.[4]
