Benten Island

The town of Onagawa, on the Sanriku coast of Miyagi Prefecture, is designated as a national park. The tsunami severely damaged the area, but it is now recovering strongly. There is a fishing area off Jinghwasan where the Oyashio and Kuroshio currents collide, and both cold and warm currents occur at the dive site. It is also interesting to enjoy diving with fixed nets, oysters, and sea squirt shelves.

The wall of ascidians is a unique sight in the northern country. Dangler fish are seen throughout the year, and spawning can be observed. You can also see many unique northern nudibranchs, dandelions, and anchidnails.
