The Site is an estuary tidal flat formed at the meeting point of the Kokuba River flowing through Naha City and the Noha River flowing through Tomigusuku City, in the southern part of Okinawa Island. It is located three kilometres inland and is affected by tidal fluctuations, with a maximum of 47 hectares of mudflat appearing at low tide. The Site is an important stop-over place for migratory waterbirds because there are abundant juvenile fish and benthos such as lugworms, which are specific to brackish tidal flat. Many shorebirds are observed and these include Pacific golden plover (Pluvialis fulva), dunlin (Calidris alpina), Eurasian curlew (Numenius arquata), far eastern curlew (Numenius madagascariensis), black-faced spoonbill (Platalea minor) and Saunders’s gull (Larus saundersi).
