伊川津貝塚

The Ikawazu Shell Mound is an archaeological site in Tahara with multiple layers of shells, pottery pieces, and stone tools. The excavations have uncovered remains spanning thousands of years of human habitation.

The site shows nearly continuous habitation from the Jomon period through medieval times. This long chronology reveals how Japanese coastal populations remained settled in this region across thousands of years.

The site contains remains of dwelling areas and hearths that show how prehistoric coastal communities organized their daily lives. You can observe evidence of social structures through the arrangement of these living spaces.

The site is easily accessible by public transportation from Tahara. Wear comfortable shoes since the terrain is uneven and you will need time to explore the excavation areas.

The shell layers follow specific patterns that reveal ancient fishing methods and changes in the coastal environment. These patterns help researchers understand the relationship between human activities and natural changes over long periods.
