Oki Islands Geopark 隠岐ユネスコ世界ジオパーク
UNESCO Global Geopark rising out of the sea of Japan
The Oki Islands are famous for their stunning seascapes and breathtaking coastal scenery, making this geopark a top choice for tourists.
Global Geoparks are geographical areas where sites and landscapes of international geological significance are managed with a holistic concept of protection, education and sustainable development, and the Oki Islands fit that description perfectly.

How to Get There
The Oki Islands are best reached by ferry.
Car ferries to the Oki Islands depart from Shichirui Port near Matsue and Sakaiminato Port near Yonago in Tottori Prefecture . The journey takes between two and a half hours and four hours depending on which island you go to. Both ports also operate a high-speed hydrofoil service for passengers only.
Oki Aiport on Dogo has flights from Osaka that take 50 minutes and from Izumo Airport in 30 minutes.
Ferries connect the islands, which has a limited bus service. Renting a car is the most convenient way to visit many of the sites, though some people prefer cycling.
Global geopark center
A good place to start is the Geopark Center located just across from the main ferry terminal in Saigon Port on Dogo, the largest island. Here you can pick up all the maps and brochures you need. The English-speaking staff here and in the Tourist Information Office downstairs can help with suggested itineraries or arranging assistance. They periodically organize bus tours for visitors who don't want to rent a car or don't have enough time to organize their own tours.
At the dozens of sites of interest around the islands there are large information boards in both English and Japanese with diagrams, photos, and easy explanations about what you can see.
There are four inhabited islands in the archipelago. The largest is Dogo, which is roughly circular with the center rising to 555 meters. The three other islands, Nakanoshima, Nishinoshima, and Chiburijima, are collectively known as Dozen, and are the remains of a sunken caldera and are individually convoluted in shape but roughly circular as a group.
Highlights of Dogo
There are plenty of sites to see in these islands. At the far northern tip of Dogo is the Shirashima Coast, a cape with viewpoints 200 meters above the sea looking out at a series of pure white islands capped with green vegetation rising out of the blue sea.
A little further down the east coast is the Jodogaura Coast. It was formed by volcanic activity 26 million years ago. You can see a delightful collection of small coves with islets, rocky beaches, cliffs, and rock formations.
There is a trail that runs along the water's edge and another up on the hillside with more expansive views and a small, free campsite. On the northwest coast is Candle Rock, an icon of the Oki Islands. You can view this spire of rock rising from the sea from the viewpoint at Ojirobama, but you need to take the sunset boat cruise to see its full splendor when the setting sun resting on its tip makes it look like a lit candle.
Highlights of the other islands
On Nishinoshima you can explore the Kuniga Coast with its natural arch and sculpted rock formations. The nearby Matengai Cliffs rise 257 meters above the sea, among the tallest in all of Japan, and are best seen from a scenic boat tour. Don't miss Mt. Takuhi, the central cone of the sunken caldera. From the top there are great views in all directions.
Mt. Kinkoji, over on Nakanoshima, while not as high as the 452-meter Mt. Takuhi, offers stunning 360-degree views over the archipelago. The Akiya Coast in the north of the island features red rock cliffs and a heart-shaped opening in the rocks. There is a beach and campsite here.
Over on Chiburijima, the smallest of the inhabited Oki Islands, you can see the red cliffs at Sekiheki, but here the cliffs have vertical stripes that alternate between black, white and other colors.
From the cliffs, beaches, coves, and mountains as well as from out at sea there is a fantastic variety of amazing coastal landscapes to see in the relatively small area of the Oki Islands.
