Welcome to Oki Islands UNESCO Global Geopark!

Oki Islands UNESCO Global Geopark is located in the Sea of Japan, about 40–80 km north of Shimane Peninsula. It is made up of four inhabited islands and many uninhabited islets. The geopark area includes marine area as well, because its remote island environment, marine life, and fisheries industry are important heritages of the geopark.

The land of Oki has experienced a number of different periods—a period as part of the Eurasian continent, a period at the bottom of a lake, a period at the bottom of a deep sea, and a period of volcanic activity about six million years ago that birthed the Oki Islands.

Here you can not only see precious geological resources and landscapes, but also discover the story of the Oki Islands: a story woven by the several hundred million year "Geohistory" of the islands' formation, the "Unique Ecosystem" that developed on the land, and the "Lifestyles and Traditions" passed down through generations of the people who call it home.
