Mount Kanmuri, Mountain peak in Hatsukaichi, Japan

Mount Kanmuri is a mountain summit in Hiroshima Prefecture that rises to 1,339 meters above sea level and marks the westernmost point of the Chugoku Mountains. The slopes feature several distinct vegetation zones and are accessible by well-maintained hiking trails.

Mount Kanmuri lies in the Nishi-Chugoku Sanchi Quasi-National Park, which protects the western Chūgoku Mountains. The mountain's summit carries a first-order triangulation point, and its upper slopes were long managed as part of the Yoshiwa village landscape. The area is also listed among the Hiroshima Prefecture natural monuments for its rhododendron stands.

The name Kanmuri is shared by several peaks in Hiroshima Prefecture, so this summit is often called Yoshiwa-Kanmuri to set it apart. You can sense this local naming tradition as you walk the trails and encounter signs using both names.

The mountain is reachable by car in about 10 minutes from the Yoshiwa Interchange on the Chugoku Expressway, which runs along its southern base. Well-marked trails begin from accessible parking areas, and conditions vary with the season and weather.

The Ota River, which flows through Hiroshima city, begins on Mount Kanmuri. A stone monument marking the river's source stands in the saddle just south of the summit, a detail many hikers pass without noticing.
