This waterfall flows from the Kusu River down a drop of 32 feet (10 m). The crest is arched and resembles a crescent moon (“mikazuki” in Japanese), giving the waterfall its name. It is also known as Uogaeri no Taki, from the fact that the fish cannot swim upstream. Komatsu Nyoin is said to have jumped to her death here after having come looking for Kiyohara no Masataka in a tale of tragic love. She is now enshrined at the Arashiyama Taki Shrine next to the waterfall.
