There are already three other official geoparks in Japan; Toya Lake-Usu Mountain Geopark, Itoi River Geopark, and Shimabara Peninsula Geopark making San’in Kaigan Geopark the fourth official member in the country.
---What is a Geopark?---
A Geopark is a territory with a geological heritage of a scientific/historical significance. Supported by UNESCO, this project is especially popular in Europe and China. The San’in Kaigan Geopark stretches across three prefectures; Hyogo, Kyoto, and Tottori, so tall three are taking part in management of the park.
