Restoration of Arakawa River upstream (Okegawa and Ageo Cities and Kawajima Town, Saitama Prefecture)

The Arakawataroemon district lying astride Okegawa City, Ageo City and Kawajima Town is one of the districts having the former Ara River channel, where a rich natural environment merged with the ambient surroundings of the wetland and lakeside forests was formed. Today, however, the decrease in the flood frequency due to the lowering of the riverbed of the main stream of Ara River and the drying of the river by sediment deposition in the former channel are advancing and the existence of this good ecological environment is threatened.
For this reason, a natural restoration conference for the former Ara River channel was established as the first project according to the Law for the Promotion of Nature Restoration in Japan in 2003 and nature restoration programs have been conducted as an important base of Ara River ecological network.
