Sanriku Coast

The Sanriku Coast (三陸海岸, sanriku kaigan) is a coastal region on the Pacific Ocean, extending from southern Aomori Prefecture,[1] through Iwate Prefecture and northern Miyagi Prefecture in northeastern Honshū, which is Japan's main island.[2] The name comes from the historical region of Sanriku (lit. "three riku"), referring to the former provinces of Rikuō, Rikuchū and Rikuzen.[3]
