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.
Agojima Island in Onagawa, is a beginner-friendly site just 5 minutes by boat from Onagawa Port. With 11–12 m depth, rugged reefs, and narrow waterways, it offers scenic terrain. Year-round residents include pink dungfish, beaked sculpin, and true booyahs, while strong tides bring rich seasonal migratory fish.
