is a waterfall on the Tanzawa River in Yamakita, Ashigarakami District Kanagawa Prefecture, Japan.
The Shasui Falls is located in the precincts of Saishō-ji, a Buddhist temple, and has been used by yamabushi and Buddhist clergy for takegyo purification ceremonies, where participants stand underneath the fall, allowing the water to strike their head and upper body.
The Shasui Falls drops in three separate plunges with a total height of 90 meters. The upper falls has a height of 69 meters, the middle falls has a height of 16 meters and the lower has a height of 29 meters. The falls are mentioned as the Shasui Falls in the Shin-Sagamikuni Fudoki of 1841, but have been known since at least the late Heian period. During the early Kamakura period, the famed monk Mongaku is said to have spent one hundred days in meditation and austerities at this waterfall, and the temple of Saishō-ji has an image of Fudo Myoo called the "Waterfall Fudō", which it attributes to Mongaku.
