Yasui Gorge

This is the best "Niyodo Blue" spot in the Niyodo River area. This gorge is known for the most beautiful autumn foliage in the prefecture, and there are many other sights to see, such as Hiryu Falls, a two-tiered waterfall with a drop of 30m that looks like a dragon twisting its body and taking off, as well as the Suisho-fuchi and Sabo dam, which change color to blue or green depending on the season and time of day, and Mikaeri Falls, which can be seen from the road.
