Izunuma and Uchinuma are lakes forming a wetland in Senhoku Plain in Miyagi Prefecture. The total area of the wetland is 4 sq. m and the water depth is only 1.6 m at the deepest. Being designated as a Ramsar Site, the lakes provide wintering places for waterfowls such as Greater White-fronted Goose (National Natural Monument) and Bean Goose and habitats for aquatic plants and insects.

Izunuma-Uchinuma Lotus Flower Festival is held from the end of July to the end of August, when the surface of the pond is covered with beautiful lotus flowers. Pale pink lotus flowers among green leaves make a brilliant contrast with clear blue sky. Flowers can be viewed from the walking trails and surrounding roads. Also, as a sightseeing-boat is operated during the festival, you van enjoy viewing the lotus flowers from the boat in the center of the pond.
