Shiudeyama Site, Archaeological site on Mount Shiudeyama summit, Mitoyo, Japan.
Located at 352 meters above sea level, the Shiudeyama Site contains foundations of fortifications, watchtowers, beacons, and pit dwellings from ancient settlements.
Discovered in 1947 and excavated from 1955 to 1957, this settlement from the Yayoi period served as a military location for monitoring sea routes.
The archaeological museum displays numerous artifacts including shell rings, antler hooks, Yayoi pottery, stone tools, arrowheads, spears, and polished axes.
The site features reconstructed pit dwellings and observation decks offering views of the Seto Inland Sea and surrounding islands throughout the year.
Research indicates similarities between the structural layout of Shiudeyama Site and the Songguk-ri archaeological site on the Korean Peninsula.
