Yoshigo Shell Mound

Yoshigo Shell Mound is an archaeological site on the Atsumi Peninsula with remains of an ancient coastal settlement. The location holds a mix of shells, bones, tools, and pottery fragments that reveal details about daily life from that period.

The site dates to the Jomon period and was excavated during the 1920s. These early investigations uncovered graves and burial practices of the people who lived there, providing important clues about their civilization.

This place reveals burial customs that were common during the Jomon era. The human remains show how people of that time organized their dead in shared graves and treated certain parts of the body in specific ways.

The on-site museum displays the excavated finds and teaches about the Jomon period. Visitors can walk from Mikawa Tahara Station and spend time exploring both the indoor exhibition and the outdoor grounds.

Among the many skeletons uncovered, evidence of a rare tooth modification was found that this population practiced. This custom was widespread at the time and shows how people expressed their identity through body changes.
