Sannai-Maruyama Site

The Sannai-Maruyama Site, located in northern Japan, is a significant archaeological site representing a large Jōmon period settlement. First occupied around 3900 BCE, the site showcases the transition from a semi-nomadic to a more sedentary lifestyle, with the construction of pit houses and elevated storage structures. Notable features include over 500 pit dwellings, longhouses, and a remarkable six-pillared structure, believed to have served a monumental or communal purpose. The site reveals intricate social structures through its burial practices, including jar-burials for infants and stone circle-enclosed elite graves. Artifacts such as earthenware, jade, amber, and obsidian hint at extensive trade networks. Abandoned around 2300 BCE, the site offers insights into prehistoric life and environmental adaptation in the Jōmon period, making it a vital cultural and historical asset.
