Mase Valley Sanjugama
A scenic valley location in Happo Town, Yamamoto County, located along the Mase River which originates in the Shirakami mountain region. The name comes from 30 potholes called Oketsu carved out of the riverbed by stones caught in the river current (Sanju is Japanese for 30). The surrounding area has a series of paths allowing you to enjoy the beautiful natural scenery interwoven with the mountain streams including the Ouketsu potholes, unusual boulders, and verdant green new growth or changing autumn colors.
