The Ojiri River flowing from Lake Chuzenji corroded the lava of Mt. Nantai covered with quartz-porphyry, and turned into a large cataract, 96 meters long and 7 meters broad at the foot. It gives forth a thunder-like noise together with twelve minor falls near by. The falls were named after the basic principle of Buddhism, "Kegon" or Avatamska. (ที่มาจากหนังสือ National park nikko)
It is a hot spring cataract rushing in torrents down a steep slope of the southern outlet of Yunoko Lake located in the mountain recesses. The cataract is 10 meters wide and 110 meters long. (ที่มาจากหนังสือ National park nikko)
It is the cascade of the water which gives the waterfall its beauty. YUGAWA river runs across the SENJOGAHARA and falls furiously on the lava bed of Mt. Nantai. The total length of this waterfall is about 210 meters and the width is about 10 meters. It was named as "RYUZU" (a dragon's head) because of the way it falls, splashing and winding among the big rocks.
