Bense Swamp located in Kizukuri Tateoka, Tsugaru City, Aomori Pref. is one of the largest swamps in Tsugaru Qausi-National Park. In the area around this swamp are numerous large and small lakes and pond. Surrounded by Hirataki Pond, Otaki Pond and Bense Pond, this swamp at an altitude of 20 m above sea level has an area of 20 ha, where the community of Nikko-kisuge (Hemerocallis middendorffii var. esculenta) forms a bright orange carpet in June, and the purple community of sword-leaved iris shudders in the breeze in July. The swamp was formed because dead plant layers such as peat moss have heaped up due to the severe climatic conditions. It is unusual that this kind of marshy plant community is formed near the beach. In Honshu and the northeastern part of Hokkaido, it can be seen nowhere other than in the wetland area around Mt. Byobuyama including this swamp. Bense Swamp is a scenic spot where visitors can enjoy bright-colored cute flowers.
