Site description The Kamogawa river originates from the Mt Ishizuchisan system in Ehime Prefecture. In the area around the mouth of the river, combined with the tidal flats of the adjacent Nakayama river, tidal flats total 383 ha, the largest in Ehime Prefecture. At tidal flats of sandy nature there live many crabs, although coastlines are protected by concrete reinforcement structures. Around the mouth of the rivers there are also paddy fields, and many birds are seen at the mouth of the rivers. In the area at the tip of the tidal flats, seaweed cultivations are carried out actively particularly in winter.
