拝ケ石巨石群

The megalithic group in Usa consists of multiple large stones strategically arranged across elevated terrain. The site forms a significant archaeological complex in Oita Prefecture.

The stone structures were built during the transition period between the Jomon and Yayoi eras, roughly from the 1st century BCE to the 1st century CE. This period marked major shifts in how people in Japan lived and worked.

The stones were used by early settlers as gathering places for rituals and ceremonies. They show how important these structures were for the spiritual and social life of ancient communities in this region.

The site has hilly terrain and requires sturdy footwear for walking across the ground and between the stones. It is best to visit in the morning when daylight illuminates the stone surfaces clearly.

The stones bear marks of human shaping that archaeologists have identified through close examination. This reveals that early inhabitants deliberately carved and positioned these stones rather than simply using natural formations as they appeared.
