On the last day of my North Tohoku trip, I visited the Sannai-Maruyama historical site in Aomori. The site was excavated in 1992 and features a vast community of early people from approximately 4,000 to 5,500 years ago. This era was known as the early to middle Jomon period in Japan.

The excavated site includes large pit-dwellings, burial pits and jars, mounds, pillars of building, storage pits, clay mining pits, and remains of the roads which showed the lives of the early settlers in the area.

There is also a museum which shows excavated tools like potteries, stonewares and other things used by the Jomon period people.
