The artificial lake "Nishikishu" in Nishiwaga Town, Iwate Prefecture, has a seasonal fluctuation in water level. The Mato Canyon is full of snowmelt water in spring and has a depth of about 20m, but during the dry summer season (July-September), the amount of water is below the knees. Observe the flora and fauna that can only be seen in this season as you pass through old bridges and valleys that emerge from the bottom of the water before it submerges in the dam.
The tributary, Madoto River, which pours into Kinki Lake, becomes like a valley when the water level drops by about 10 m during the dry season from July to October. The valley seen from below is dynamic! River trekking along the bottom of Marot Canyon, where you can observe the flora and fauna seen in the summer while walking along the river. It is a tour that you can walk in the water below your knees. There are not many ups and downs, and you rarely climb or swim on rocks. There is a part where you can soak it in the water up to your waist.
You will make your own way to the meeting points
