At Sannai-Maruyama, on the northern edge of Aomori City, the past is not represented by a single monumental tomb or palace. It is a settlement landscape: house remains, postholes, refuse deposits, graves and broad open spaces reveal a community that occupied the site for centuries. Excavations beginning in 1992 uncovered a large village dating from about 3,900 to 2,200 BCE, during the Early and Middle Jomon periods. The long span is central to understanding the place; it was not a brief camp.
Archaeologists found pit dwellings, raised-floor buildings, storage features and the remains of adults and children. Potsherds and stone tools appeared alongside wooden objects, lacquerware, bone and antler items, and plant remains. Many organic materials survive because wet, oxygen-poor deposits in a nearby valley slowed decay. The evidence lets visitors look beyond reconstructed roofs toward food, craft and household life, while reminding us that preservation depends on the conditions in which objects were buried.
