Omori-cho was a prosperous mining town of the Iwami Ginzan Silver Mine. The scene of rows of houses with red roof tiles continues along the valley where the Ginzan River flows. This town has still the layout of the Edo period and retains the atmosphere of the past, even as the people conduct their modern lifestyles. Throughout the townscape, the green tuff created by volcanoes during the formation of the Japanese archipelago has been widely used as a building material, and the stone walls and other stone structures create an orderly scene. The remains of stone quarries that can still be found in various places around town create a unique atmosphere.
