Chūgoku Mountains Mountains

The Chugoku Mountains are an east-west mountain chain across the Chugoku region of western Honshu in Japan, forming the backbone of that region. The range includes peaks reaching around 1,700-1,800 metres and shapes regional geography and climate.

The mountains have long formed natural boundaries within western Honshu and influenced historical travel and settlement patterns; local transport routes and towns developed around accessible passes. Forestry, mountain agriculture and small-scale mining have featured in the region’s economic history.

The range runs roughly east-west across the Chugoku region of Honshu, separating the Seto Inland Sea coast to the south from the Sea of Japan coast to the north. It spans multiple prefectures and lies west of the Kansai region.

• Watershed effect: The range forms a watershed between the Seto Inland Sea to the south and the Sea of Japan to the north, influencing local climate and river courses across western Honshu.
• Elevation: Highest summits, such as Mount Daisen, reach roughly 1,700 to 1,800 metres, offering alpine terrain, ski areas and hiking routes.

The Chūgoku Mountains are accessible via multiple regional JR rail lines and national highways. Major gateway cities include Hiroshima and Okayama; from there local buses and roads reach trailheads and mountain towns.

• Use the Chugoku region's rail network (JR lines) and local buses to reach trailheads; some routes require a car.
• If planning to hike, check for alpine huts and seasonally closed paths.
