Yuzawa Funsento

Hot springs bubbling up are a common feature along the Yuzawa Ravine, through which flows a tributary of the Kinugawa River. It's known for the sinter cones (funsento) that have formed in several places. Calcium carbonate and other hot spring deposits accumulate around the hydrothermal vents, forming conical or bamboo shoot-shaped formations called sinter cones. Larger ones can reach 80 centimeters, but the exteriors tend to be soft and collapse very easily. This sinter cone spouts a continuous flow of 90-plus-degree water. It was designated as a National Natural Monument in 1922.
