Osarizawa Mine
Around Mt. Omori, there were a large number of ore vein groups, including Akasawa in the east, Motoyama and Tagori in the west, Nagasaka in the south, and Saido and Sakiyama in the north. Each of them was independently developed as a separate mine until the middle of the 19th century.
