Tagoyano Shell Mound, Archaeological site in Tsugaru, Japan.
The Tagoyano Shell Mound spans 20,076 square meters and reaches 15 meters in height, containing numerous layers of shells and artifacts from early settlements.
The shell mound, designated as a National Historic Site in 1944, contains remains from the early to middle Jōmon period between 4500 and 2500 BCE.
Excavations revealed human bones, pottery, stone tools, and marine mammal remains, indicating a society that relied on both marine and terrestrial resources.
The site remains closed during winter months from December to March, with guided tours available on weekends and holidays from April through November.
Over 50 incomplete bracelets crafted from Benkeigai clam shells were discovered, suggesting the location served as a manufacturing center for shell ornaments.
