Kegon Falls are located at Lake Chūzenji (source of the Oshiri River) in Nikkō National Park near the city of Nikkō, Tochigi Prefecture, Japan. The falls were formed when the Daiya River was rerouted by lava flows. About twelve smaller waterfalls are situated behind and to the sides of Kegon Falls, leaking through the many cracks between the mountain and the lava flows.
At 97 m high, it is one of Japan's three highest waterfalls. In the autumn, the traffic on the road from Nikko to Chūzenji can sometimes slow to a crawl as visitors come to see the fall colors.
