Ikegami-Sone Site

The Ikegami-Sone site is a significant archaeological site located in the Kansai region of Japan. Spanning 600,000 square meters, it is a large Yayoi period settlement characterized by its extensive infrastructure, including a double ring of moats and a substantial paddy field, indicating advanced agricultural practices. The site's central feature is a large pillar building, constructed around 52 BCE, possibly serving as a ritual or administrative center. Artifacts discovered at the site, such as Yayoi pottery and stone tools, suggest it was a hub for production and distribution, particularly for green schist stone knives. The absence of ironware indicates a delay in iron usage compared to other Yayoi sites. Its importance is further underscored by evidence of interaction with continental cultures, as seen in a dragon-decorated jar. The site offers valuable insights into the socio-economic and cultural aspects of the Yayoi period.
