In the former town of Uwa there is a natural spring, the water of which is known as Kannon Spring Water (観音水, Kannon-sui?). This water was designated as one of Japan's 100 best water sources (名水百選, meisui hyakusen?) by the Ministry of the Environment in March 1985. Hiking trails along the spring's mountain rivers are a popular destination in the summertime. The spring is also used for somen nagashi (そうめん流し?), a Japanese cuisine where bundles of cold somen noodles are set into a stream of water that flows down a track, with hungry patrons waiting alongside.
