This pond is a reservoir built for irrigation of rice paddies, and although its official name is “Ookamidani Reservoir,” it was given the name “Daisen Pond” because of the reflection of Mt. Dausen. The contrast between the seasonal colors and Mt. Daisen is a delight to the eyes of visitors. In summer, the pond is a popular camping site, and has been designated by the prefecture as “Inpaku no Meisui (Fureai no Mizuibe)” (famous water of Inpaku).
