The gorge was formed by erosion of Aso lava by the Gokase River, and is a scenic spot with cliffs of 100 meters at the highest point and 80 meters on average for 7 km.
It is located within the Aso Kujyu National Park.
The gorge has several waterfalls, including Tamadaru Falls, Manai Falls, and Araragi Falls, as well as steep cliffs. The contrast of the clear blue water with the fresh green and autumn leaves is especially beautiful.
Visitors can rent boats to get a close-up view of the steep cliffs and the waterfalls.
There is an approximately 800-meter promenade along the canyon, where visitors can appreciate the beauty of the canyon, including the 17-meter-high waterfall, even without taking a boat.
It is also known for its summer Somen-nagashi (Noodle Noodle Making Process) using fresh water from the canyon.
During the summer, the Manai Falls in the valley are illuminated, creating a fantastic sight.
