Designated as a historic site on March 17, 1995
Stone circle from the early phase of the Late Jomon period (approx. 2,000 BC). It is located on a tongue-shaped plateau at an altitude of 80 to 160 m overlooking the Aomori Plain while sandwiched between the Arakawa River and the Nyunai River running across the west foot of Mt. Hakkoda in southeastern Aomori City.
The stone circle is a large monument of 55 m in diameter. The center ring has a diameter of 2.5 m, surrounded by another ring of 29 m in diameter and a third ring of 35 m in diameter. These three complete rings are encircled by small stone circles of about 4 m in diameter and part of a fourth ring of stones. The outer two rings of the stone circle were made by placing oval stones vertically and horizontally as if building a stone wall. This method of arranging stones is very rare, not just in Aomori, but for all of Japan, and is called the Komakino style of stone arrangement.
In addition to the stone circles, the excavations revealed the remains of structures used in everyday life, such as pit dwellings (housing), storage pits and dumping grounds, spring water structural remains as well as those necessary for burial, including pit graves and pot burials.
Apart from pottery and stone implements used in everyday life, artifacts with strong religious overtones, such as clay figurines, miniature pottery, animal-shaped clay products and triangular stones, have also been unearthed around the graves adjacent to the stone circle and the dumping grounds. In particular, more than 400 triangular stones have been unearthed, indicating that certain rituals were performed with the stone circles, etc.
Stone circles are extremely advanced and high-quality relics of the civil engineering technology of the Jomon period. They suggest that a unique culture used to exist on the Japanese archipelago and present outstanding material evidence of the religious views of the Jomon period, permanent settlements based on hunting, fishing and gathering in symbiosis with nature.
