The Ochozu-no-taki Waterfall is in the upstream of the Numagawa River that runs through Tateishi-machi in Tosu City, Saga Pref. It is a beautiful waterfall with a height of 10 meters. The name “Ochozu (wash basin)” is derived from an old story that yamabushi (mountain ascetics) who performed the ascetic practices in the mointains around this waterfall often visited the waterfall to purify their hands and bodies in the water. The images of Nyoirin Kannon, Dainichi Nyorai, and Fudo Myoo placed on the clif beside the faterfall show that this was the holy place in the old days. The area around the waterfall is now developed and maintained as a city’s sightseeing spot, where visitors can enjoy swimming in the pool made in the river, walking along the trail, and camping.
