Overview of the Ruins of the 
Iwami Ginzan Silver Mine

Map of Iwami Ginzan Kaido (Transportation Routes)
In the vicinity of the mine are two ports (Tomogaura and Okidomari) which were used for sending silver out and bringing supplies in, settlements, and the streets of Yunotsu, the only hot spring town in Japan designated as an Important Historic Buildings Preservation District. The Iwami Ginzan Kaido (Transportation Routes) Tomogaura-do and Yunotsu Okidomari-do connected the surrounding areas with the silver mine. Scattered throughout the site are the ruins of castles that were engaged in the struggle for control of the silver mine.

Tomogaura Area

On the coast of the Sea of Japan 6km northwest of the Sakunouchi Area, Tomogaura was the port from which silver and silver ore was shipped to Hakata, Kyushu, during the years when Iwami Ginzan began to develop in the early 16th century. Early records show a flourishing port visited by many trading ships from Hakata to load silver ore. In the early Edo Period it became no more than a fishing village, and the consequent lack of major projects meant the original shape of the medieval port was preserved. Among the remains are the hanaguri-iwa moorings located on both banks of the port. A shrine dedicated to the safety of sea traffic, settlements in the valley where the land is still divided into square administrative zones, silver ore storehouses, administrative buildings, and wells for use by vessels remain.

Okidomari Area

Situated on the coast of the Sea of Japan 8.8km west of the Sakunouchi Area, Okidomari is the port through which silver was shipped and supplies received for Iwami Ginzan during the late 16th century when the Mori Clan took control of the mine. On both banks hanaguri-iwa moorings remain, with mountaintop castles that served as military bases perched on the hilltops at both ends. The port extends into a sand beach area, and from here leading back into the valley extends a square-divided settlement which dates back to the 16th century. Other remains include a shrine dedicated to safe navigation, wells used by vessels, and a small shrine for the protection of the settlement from fire.
