About San’in Kaigan Geopark
In December 2008, the San’in Kaigan Geopark was designated as a Japanese Geopark by the Japan Geopark Committee. On December 4 (December 3 local time), 2010, the San’in Kaigan Geopark was admitted to the Global Geoparks Network during a conference held on Lesvos Island, Greece.
In August 2014, four years after its designation in 2010, the San’in Kaigan Geopark received an on-site evaluation. On September 23 (September 22 local time), during the 6th International UNESCO Conference on Geoparks held in Stonehammer Global Geopark, Canada, the revalidation of the San’in Kaigan Geopark as a member of the Global Geoparks Network was decided. As a result, the San’in Kaigan Geopark will hold its position as a global geopark for another four years until 2018.
