River Ara

The River Ara is a river located in Japan. It is a major river in the Kantō region of Honshu, the largest island of Japan. The Ara River flows from Mount Kobushi in the Chichibu Mountains, through Saitama Prefecture and Tokyo, and empties into Tokyo Bay. It is known for its relatively steep gradient in its upper reaches and its importance as a source of water for the Tokyo metropolitan area. The river is also utilized for recreational activities such as fishing and cycling. Historically, the Ara River has been subject to flooding, leading to significant engineering projects to manage water flow and prevent damage to surrounding areas.
