Nikkō National Park (日光国立公園, Nikkō Kokuritsu Kōen?) is a national park in the Kantō region, on the main island of Honshū in Japan. The park spreads over four prefectures: Tochigi, Gunma, Fukushima, and Niigata, and was established in 1934.
Ryūzu Falls (龍頭滝, -taki, lit. "Dragon's Head Waterfall") is a waterfall located upstream from the Yugawa River which makes its way into Lake Yunoko and Lake Chuzenji. It is located near Nikkō in Tochigi Prefecture, Japan.
Ryūzu can be translated as 'Dragon's Head', and is so named because its twin falls are said to resemble a dragon's head.
