Zengoro Falls
Zengoro Falls formed from volcanic rock after the last eruption of Mt. Norikura some 43,000 years ago. The cascade is relatively large at 8 meters wide, with a 21.5-meter drop. Erosion of the rock is slowly moving the falls upstream.
The falls get their name from a local legend about a logger named Zengoro, who was almost pulled into the river by a giant char while fishing. The story says he barely escaped with his life, and his name has been attached to the falls ever since.
In winter, a lack of sunlight causes the water to freeze a deep blue, and the completely frozen falls are a popular snowshoeing destination. Some trails that pass nearby lead to many of the other waterfalls and scenic spots around Norikura.
