Origin of Ecosystem of the Oki Islands

What makes the ecosystem unique?

So how did Oki’s mysterious ecosystem come about? Recent research is gradually bringing the causes to light.

Here, the movement of plant and animal life to the islands during the glacial period (as identified through research conducted on Japanese cedars) and the environmental impact of the Tsushima Danryu (Tsushima Warm Current) that flows through the Sea of Japan are the relevant factors that we will discuss below.
