Oki Islands Geopark Museum

In this exhibition facility, you can learn about the four Oki Islands and the Oki Islands UNESCO Global Geopark.
By combining the museum's exhibitions with experiences and scenery outside in the geopark, you can gain a deeper appreciation for the Oki Islands and the Earth.

Discover the Oki Islands Through Each of their "Histories"

The Oki Islands Geopark Museum, located next to Saigō Port, introduces the Oki Islands by exploring the features and hidden charms of the region, and their surprising connections.

Divided into three main zones, the museum begins in the first zone by introducing the "Geohistory" of the Oki Islands and how they formed and changed over the years. The second zone introduces the islands' "Unique Ecosystem," featuring dioramas and taxidermy specimens, and explaining how such a diverse ecosystem came to be. In the third zone, the "Lifestyles and Traditions" of the local people are traced back as far as 30 thousand years ago through obsidian trade, the exile of emperors, Oki Islands Traditional Sumo, and other culture and history unique to the Oki Islands.

The museum also features a large monitor and projection mapping over a 3D model of the Oki Islands. Here you can enjoy one unified story from the birth of the Earth to the present-day Oki Islands.

Exhibition Overview

The Oki Islands Through their "Histories"

Remote islands in the Sea of Japan—the Oki Islands UNESCO Global Geopark. How did the land that forms these Oki Islands come to be? What kind of plants and animals inhabit them, and how do the people here live their lives? These answers are found in the grand story of the Earth and life.

The Oki Islands in Earth's History

It has been about 4.6 billion years since the beginning of the Earth. Over that long period of time, the continents have repeatedly joined together and split apart, and life has repeatedly flourished and become extinct. Here in this land called the Oki Islands, we can catch a glimpse of one part of the Earth's long history.

History of Life on the Oki Islands

After experiencing a number of changes in the land, the Oki Islands became remote islands about 10 thousand years ago. The living things found here hold a close connection with this history. A variety of plants and animals from all different regions live together on the islands, creating an unusual space that cannot be explained simply by the fact that they are remote islands.

Human History of the Oki Islands

Oki obsidian was brought about by former volcanic activity. Since 30 thousand years ago, many people from different regions have interacted with each other as they sought after this obsidian. Within human activity dating back tens of thousands of years, there is history and culture only found in the Oki Islands, some of which still continues today.
