Takkiri Ravine is located in a nook of one of the ten gorges of Yabakei, Shiiya Yabakei Gorge. When people hear Shiiya, they often think of magnificent watery landscapes, such as the East and West Shiiya Falls, or of scenes of rock columns and rock walls, but Takkiri Ravine is a place with gentle waters where people come to play. Here, people become one with the water.
　The ravine is in the upstream portion of Nukumi River entering from Innai Valley. The riverbed consists of a single welded tuff lava rock from Yabakei stretching two kilometers long. The water flowing here is shallow, only ankle-deep. This gentle ravine ranges from 10 centimeters deep to 20 or 30 centimeters deep at most, even in its deepest spots. The riverbed is smooth, letting you splash in it as you walk along.
　The ravine is at times narrow and at times broad, and is covered by a canopy of natural forest trees. The colors change with the seasons. In spring, they are a bright green that is easy on the eyes, in summer the color deepens, and in autumn, they turn red. You can even see icicles in winter.
　But the best time to play in the water is, of course, summer, after the camp sites in the ravine have opened. During summer break, the ravine is full of families. There is a walkway along the mountain stream, but it is ignored. People put on sandals or rubber shoes and walk in the water. Forget the heat of summer in the cool breeze beneath the sunlight sparkling through the canopy. Walk about 30 minutes from the gate to find Otobu falls, dropping right before your eyes. It is 27 meters high. Looking down on from atop the waterfall is dangerous.
　This place is, of course, good in spring and fall as well. Listen to the warble of songbirds in spring, and find yourself surrounded by red leaves in autumn. The autumn leaves are colorful, turning red and yellow. Fallen leaves float along the river. This place also serves as a living classroom for studying trees and plants. It was also chosen a top drinking water spot in the “Top 15 Famous Waters of Toyo-no-Kuni.” You’ll want to bring your camera for the snowscapes in winter.

　Although it is in a different basin and on a different route, the nearby Otani Ravine is also made from a single rock. Located about eight kilometers upstream of Name River, the riverbed here is steep and suitable for strong legs.
