Yonago Waterbird Sanctuary, Bird sanctuary in Yonago, Japan.

Yonago Waterbirds Sanctuary is a 28-hectare wetland reserve beside Nakaumi Lake with viewing points, walking paths, and a nature center featuring large windows facing the water. The layout allows visitors to observe birds at different locations throughout the property.

In the 1960s, agricultural development threatened to alter Nakaumi Lake's environment, but local residents prevented these changes. The sanctuary was officially created in 1995 to protect the area.

The park opened on 22 October 1995 after local residents campaigned to keep the last remaining roost pond for tundra swans on the reclaimed Nakaumi land. The name Yonago Waterbird Sanctuary is also used in English. The site was a filming location for the 1996 NHK drama Tori Kaeru, starring Yoshiko Tanaka.

The sanctuary is about 35 minutes by car from the Yonago Interchange on the Yonago Expressway and about 20 minutes by car from Yonago Airport. By bus, get off at "Yonago Waterbird Sanctuary Entrance" (15 minutes on foot) or at "Nokoshi" (20 minutes on foot). The gate closes at 17:30; from November to March it opens at 7:00 on weekends and holidays but at 9:00 on weekdays. It is closed on Tuesdays and the day after holidays.

The sanctuary's pool is the last remaining roost for tundra swans in Nakaumi: as reclamation filled in the lake's other shallow roosting spots, this pond of the Hikona reclamation area became the only one left, which is why citizens campaigned to protect it. Up to about 10,000 birds are recorded here annually.
