Sannai-Maruyama
Sannai-Maruyama, in Aomori, northern Japan, was found in 1992 during survey work for a baseball stadium. It turned out to be one of the largest Jōmon settlements, covering about 40 hectares.
Hunter-gatherers used the site from about 3900 BCE, and it grew into a long-lived village with longhouses, storage pits, more than 500 burial pits and a great building on six chestnut posts, built around 2600 BCE. Finds include clay figurines, baskets and lacquerware. The village ended around 2300 BCE. It is part of the UNESCO-listed Jōmon Prehistoric Sites in Northern Japan.
