The Ryuzu Fall is one of the finest three waterfalls of Oku-Nikko, parallel to this are the Yutaki Fall from Lake Yuno-ko and the Kegon Fall from Lake Chuzenji. The Yukawa River, which flows out of Lake Yuno-ko into Lake Chuzenji, rapidly runs down through the surface of melted rocks produced by the eruption of Mt. Nantai and forms this beautiful waterfall. As the flow is divided in two near the foot of the fall and it looks like a dragon’s head, the waterfall is called “Ryuzu (the head of a dragon).” The water dynamically flows on the long step-like lava and gracefully dives into the bottom. You can enjoy azalea in spring and autumnal leaves in fall. In winter, when everything is covered with snow, you will also experience the mystery of nature, the frozen waterfall, before which you may feel as if time has stopped.
