Tataranuma Park is a large water-based recreation area centered around the Tataranuma reservoir in Tatebayashi, Gunma. It serves as a primary migratory site for thousands of wild swans that arrive from Siberia each winter. The park features a walking circuit around the reservoir, which spans approximately 4 kilometers. During the spring, the park is notable for its blooming cherry blossoms. The area includes the Tatebayashi Wild Bird Forest Nature Center, which focuses on local wetland conservation. Wooden walkways and observation decks are positioned to allow birdwatching without disturbing the local ecosystem. The reservoir was historically constructed for agricultural irrigation in the region.
