The Kamishiroiwa site is located on a
river terrace 3.5 kilometers from the confluence of the Omi River with the
Kano River and covers approximately 3 hectares. The site contained the foundations of
pit dwellings from 3000 to 4000 years ago and an indeterminate number of tombs. Of note were a number of
stone circles, one of which was 12 meters in diameter and contained elongated stones in its center which may once have been upright monoliths. Smooth river rocks were mostly used; however, some of the stones in the structure were polished to a flat surface. Outside of the stone circle, some 60
prehistoric storage pits were discovered, containing a large number of artifacts, mostly
Jōmon pottery and
stone tools. This included a clay token in the form of a human face. Some of these artifacts are now on display at the nearby . The site is open to the public as a park and is located about three-minutes on foot from the "Shiraiwa" bus stop on the Nakaizu Tōkai Bus from
Shuzenji Station. ==See also==
