Izunuma and Uchinuma (伊豆沼・内沼) are a pair of interconnected freshwater lakes in the alluvial plain of the Hasama River, a tributary of the Kitakami River in Miyagi Prefecture, Japan. In 1967 the birdlife and habitat of the lakes were designated a Natural Monument. In 1985 an area of 559 hectares was designated a Ramsar Site. In 1996 the sound of the Izunuma-Uchinuma greater white-fronted goose was selected as one of the 100 Soundscapes of Japan by the Ministry of the Environment.
