Shibokuchi Midden

The Shibokuchi Shell Mound, a prefecturally-designated historical site, is the oldest shell midden in the Tama Hills area, dating back to the late early Jomon period (about 7,000 years ago) and is known to be the inspiration for "Shimoguchi pottery". It was a dumping ground in ancient times and is still filled with many shells discarded by the people of that time.
