Umenoki ruins

The Umenoki ruins, located in the city of Hokuto, Yamanashi, Japan, represent an important archaeological site from the middle Jōmon period, approximately 5000 to 4500 years ago. This site features a well-preserved settlement with up to 150 pit dwellings arranged around a central elliptical plaza. The dwellings, characterized by their conical roofs, suggest a well-organized community structure. Artifacts such as Jōmon pottery and stone tools have been uncovered, providing insights into the daily life and technological advancements of the period. The site's location on a gentle slope facing the Yuzawa River, along with its proximity to other Jōmon sites, highlights its strategic and potentially agricultural importance. Now preserved as the Umenoki Archaeological Park, it offers a valuable glimpse into prehistoric Japanese society.
