San'in Kaigan Geopark

San'in Kaigan Geopark, UNESCO Global Geopark in San'in region, Japan

San'in Kaigan Geopark is a protected geological area spanning three prefectures with diverse natural formations along the coast and inland. The site features towering sea cliffs, cave systems, hexagonal basalt columns, and sandy beaches that display different stages of geological development.

The geopark received official designation as a Japanese Geopark in 2008 and was admitted to the Global Geopark Network in 2010. This recognition marked its importance for understanding the geological processes that shaped the entire Sea of Japan region.

The coastal communities here have shaped their way of life around the rocky shores and natural formations. Traditional fishing practices and resource management reflect how people have adapted to living alongside these geological features.

The geopark can be reached from several entry points connected by walking paths of varying difficulty. Starting with easier routes along the coast before attempting more challenging trails to inland formations helps visitors pace their exploration.

The basalt formations at Genbudo Cave display perfectly formed hexagonal columns created when lava cooled during the formation of the Sea of Japan. These geometric patterns are a natural result of how molten rock cools and contracts evenly in this specific way.
