Our guide
The Sannai-Maruyama Site, southwest of central Aomori, is the remains of a very large Jōmon-period settlement — some 40 hectares — found in 1992 when the prefecture surveyed the ground for a planned baseball stadium. The finds, among them storage pits, above-ground storehouses and long houses, have helped archaeologists understand the Jōmon people's shift to a settled life and the way their communities were organised. The site is also a museum.
It is open 9:00–17:00, until 18:00 in Golden Week and from June to September, and closed on the fourth Monday of each month. Shin-Aomori Station on the Tōhoku Shinkansen is about 1.8 km away in a straight line. Aomori Museum of Art is only about 0.6 km off, and Nebuta Museum Wa Rasse about 3.9 km.

What this place is
The Sannai-Maruyama Site (三内丸山遺跡) is an archaeological site and museum located in the Maruyama and Yasuda neighborhoods to the southwest of central Aomori City in Aomori Prefecture in northern Japan, containing the ruins of a very large Jōmon period settlement. The ruins of a 40-hectare (400,000 m2; 99-acre) settlement were discovered in 1992, when Aomori Prefecture started surveying the area for a planned baseball stadium. Archaeologists have used this site to further their understanding of the transition to sedentism and the life of the Jōmon people. Excavation has led to the discovery of storage pits, above ground storage, and long houses. These findings demonstrate a change in the structure of the community, architecture, and organizational behaviors of these people.
