Restoration of Ara River downstream (Edogawa Ward, Tokyo)

Downstream of Ara River, wetland existed in the decade starting in 1955, but it has mostly been lost as a result of promotion of flood channel construction and low water bank protection improvement.
Therefore, efforts are being made to not only conserve the existing natural areas but also create new natural areas and establish a natural area network for the purpose of conservation of the reedy fields, conservation and regeneration of the muddy flats and regeneration of the wetland on the flood channel.
Today, a muddy flat regeneration test is being conducted in Komatsugawa district and a natural restoration plan based on new knowledge including bank protection improvement and a wave-absorbing facility installation is being researched.
