Kōraku-kei is a breathtaking scenic area located along the Shorenji River, a tributary of the Nabari River. Its most striking feature is the approximately 8km stretch of columnar jointing rock faces, which look as if they were precisely carved by an axe. This unique geological formation is a masterpiece of natural sculpture. In autumn, the entire mountain transforms into a sea of fiery red and orange, while in spring, the landscape is adorned with the bright colors of Kerria japonica and azaleas. It remains a beloved destination for hikers and those seeking a scenic driving route.
The landscape of Kōraku-kei is a testament to the passage of geological time, where the natural formations have been preserved in their raw, magnificent state. The orderly, geometric patterns of the columnar jointing tell a story of the earth's ancient history. The area's beauty is so highly regarded that it is sometimes compared to the famous Yabakei in Kyushu, and it has long been cherished as a place to appreciate the sublime artistry of nature.

The area is dotted with several remarkable landmarks. Most notably, the rock formations known as "Tengupillar Rock" (Tengupillar-iwa) and "Byobu Rock" (Byobu-iwa) draw significant attention due to their grand and imposing presence. These sites serve as iconic symbols of nature's dynamic sculpting power. Under a clear blue sky, the sight of the mountainside covered in autumn colors creates a breathtakingly colorful tapestry. The interplay between the flowing river and the sheer, vertical rock walls offers a powerful sense of nature's strength.
The charm of Kōraku-kei lies in its changing seasonal expressions. During autumn (mid-to-late November), the entire mountain is dyed in shades of red, orange, and yellow, marking the peak of the foliage season. This is the most spectacular time for hiking and scenic drives. In contrast, spring brings a different beauty with the blooming of yellow Kerria and colorful azaleas, offering a refreshing and colorful experience. Visiting in different seasons allows you to witness the diverse faces of this natural wonder.
