The view of the waterfall looming in front of one after another is spectacular, in a valley where the clear stream slides wildly down the granite riverbed in a lush forest. The valley road along the mountain stream is a 30-minute walk from the Nishizawa valley entrance bus stop, and goes back from the Futamata suspension bridge to the left bank of the river. To see a variety of waterfalls and oddities, such as Mie no Waterfall, Ryugami Waterfall, Mother Abi, and Frog Rock, the climax leads to a spectacular Nanatsugama Five-dan Waterfall consisting of seven waterholes and five waterfalls. From here, the road moves to the opposite bank to the return course. Although it is a short distance from the ravine, it returns to the bus stop while looking at the former remains of the forest track, etc. About 9.5km per lap, 3 hours 30 minutes to 4 hours per lap. It is beautiful in mid-May, when a crowd of rhododendrons flowers, let alone during the period of fresh green and autumn leaves. The road is closed in winter.
