Shasui Falls (洒水の滝, Shasui-no-taki) 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.

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.
