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.[3]

HistoryEdit

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]

MediaEdit

This river is also depicted in many anime such as: Toaru Kagaku no Railgun
