 Chōjagahara Site

The site is located on a hill about 80 meters above sea level, near the Himegawa River, and contains the ruins of a large village from in the middle of the Jōmon period (5,000 to 3,500 years ago), which included a production base for jadeite stone axes and jade beads.The site has been excavated three times since 1945 by a team from Keio University, but the portion of the site excavated so far is only about 3% of the complete site and 10% of the village.
