Tagoyano Shell Mound

Tagoyano Shell Mound is an archaeological site in Tsugaru containing layered deposits of shells and artifacts from ancient settlements. The location preserves evidence of human habitation spanning thousands of years during early periods of settlement in this region.

The site was designated as a National Historic Site in 1944 and contains remains from the early to middle Jōmon period. The deposits provide important evidence about how early societies developed and adapted to their environment over many centuries.

The site reveals how people here depended on both ocean and land for survival. The discoveries of bones, pottery, and tools show a daily life centered on fishing and gathering from nearby waters and forests.

The site is closed during winter months from December through March. Plan your visit for the warmer season when access is easier and the grounds are more accessible for exploration.

More than 50 incomplete shell bracelets were discovered here, suggesting this location served as a manufacturing center for shell ornaments. This finding reveals specialized craftwork that took place within this ancient community.
