Kegon Falls is a waterfall located in Nikkou, Tochigi Prefecture, which according to legend was discovered by Shoudou. It was named for the first sutra of Buddhism, the Avatamska Sutra (Kegon-kyou in Japanese). The waterfall is formed by Daiya River, the only river out of Lake Chuuzenji after it was dammed by eruptions on Mount Nantai, falling over a 97-meter cliff. Is it one of Japan's three great waterfalls.

The waterfall is also infamous for suicides, starting with an 18-year-old high school student, Fujimura Misao, who leapt from the waterfall on May 22, 1903 after writing a poem on an oak tree nearby.
