The Sannai-Maruyama is a famous site which had been known since the Edo Period. Excavation survey, which was started in 1992, revealed a large a large settlement of the Early and Middle Jomon Period (about 5,500 to 4,000 years ago). Many pit-dwellings, pillar-supported buildings, mounds, burial pits and jars, as well as numerous number of pottery and stone implements, wooden objects, bone and antler artifacts were discovered.

Given to it’s significance ahead, Aomori Prefectural Government decided to preseeve this site in 1994. We started the maintenance and public viewing project of Sannai-Maruyama in 1995, and the Jomon Jiyukan was opened in November 2002. Sannai-Maruyama Site was registered as a national historical site in March 1997, as a special national historical site in November 2000, and 1,958 artifacts were registered as important cultural properties in May 2003.

Aomori Prefecture will continue to preserve and maintain the Sannai-Maruyama Site as a park where visitors can experience the Prehistoric “Village” life of the Jomon Period.

This was a pretty cool place. You can go inside the old homes and see how it’s set up. You really get taken back in time at this site.
