The Hōrai Valley (蓬莱峡, Hōrai-kyō) is a geographical area that is located in the Rokkō Mountains, Hyōgo, Japan. This valley is a part of Setonaikai National Park in Japan. The name of Hōrai Valley coming from a name of the mountain in a mystical land found in Chinese mythology.

Horai Valley is located along the upper reaches of the Ōtada River in the Rokkō Mountains. Although the valley is considered to be a badland, the rugged terrain found here is rare in other badlands around the world. The valley is characterized by its white granite cliffs that stretch up to a hundred meters high, creating sawtooth-like ridges. This granite is brittle enough to be easily broken by the hands of climbers.

Because of its alien landscape, this location has often been used as a movie set for Japanese filmmakers. It is also a frequent destination for climbers and tourists alike.
