貝の花貝塚, Archaeological midden in Kisarazu, Japan.
Kainohana Shell Mound is an archaeological site in Kisarazu containing remains from the Jomon period. The location holds thick layers of shell deposits, animal bones, and pottery fragments that accumulated over thousands of years.
This site dates to the Jomon period, thousands of years ago when Japan was inhabited by hunter-gatherers. The layers were deposited over many generations as people lived here and left their waste behind.
The excavated layers show how early coastal inhabitants sourced and prepared their food. You can see which shellfish and fish were eaten and how vital the ocean was to these communities.
You can view the archaeological findings at the nearby Kasori Shell Mound Museum, where the main artifacts are displayed. The museum helps explain the significance of the layers and how people lived back then.
The different shell layers allow researchers to track environmental changes over long periods of time. Each layer is like a time window showing how climate and living conditions shifted thousands of years ago.
