Full view of the Sannai-Maruyama Site

This is a large settlement site from the middle of the Early Jomon period to the end of the Middle Jomon period (approx. 3,900 – 2,200 BC), representing the Jomon archaeological sites of Japan. It is located on a 20 m high terrace on the right bank of the Okidate River, at the tip of a rolling hill extending from the Hakkoda mountain system in the southwest part of Aomori City.

The site covers an area of 42 ha, where the remains of pit dwellings and pillar-supported buildings, aligned pit graves, buried pottery, mounds, storage pits, roads and the remains of large buildings are systematically arranged. A great amount of earthenware and stoneware have been unearthed, including approximately 2,000 clay figures (the largest in Japan), animal and plant remains unearthed from low-lying areas that show the dietary life and the environment, and organic remains such as wood products, bones and antler objects, baskets and lacquerware, as well as jade and trading goods like obsidian from distant lands and asphalt.

These unearthed remains and articles present a real picture of stable settlements. However, the analysis of food residues and lifestyles at that time has provided no evidence of agriculture and livestock farming.

Various structures were constructed in the same place for a long time, which means systematic land use. Pollen DNA assays and other research have made it clear that Jomon people were actively engaged in the natural surroundings with Japanese beech and other deciduous broad-leaved trees to maintain and manage the natural resources, and that they established an artificial ecosystem called Jomon satoyama (community-based woods) consisting of useful trees such as chestnuts, walnuts and lacquer trees to sustain their lives.

The way of land use for sustainable settlement by skillfully using natural resources presents an outstanding example of negotiation between humans and the environment.
