Okama is the crater lake which is around the boundary of Zao-machi, Katta-gun, Miyagi and Kawasaki-machi, Shibata-gun. To turn the color various by how to take on a sunbeam, it’s also called “Goshikinuma”.
It’s circled in 3 peaks in Kumanodake, Kattadake and Goshikinuma. A crater lake of about 325m of diameter and a round shape of about 27m of water depth. The surface of the lake praises water with the emerald color, and it’s the mysterious atmosphere compared with a violent crater wall. When the fixed depth is exceeded, fish don’t live because the lake is strongly acid with the special double warm water beds where the water temperature rises.
