This scenic spot is located at the end of the Ninoashi Forestry Road, in the deepest part of Nanasawa. It is the start of the trekking route from the Atsugi side to Oyama, at the point where a mountain stream that takes its source from the underground water at the massif of Mt. Oyama flows in to join the Yataro River. The currents of the Yataro River create the finest valley scenery. This is a spot to enjoy cool temperatures in the summer. The nearby area is also dotted with waterfalls, and clusters of oriental paper bush can be found everywhere in this spot with many highlights.
