The stones here are placed in the shape of a square instead of a circle. While the reason for this is unknown, some say the position of the stones connects to a single line on the day of the summer solstice.

By the way, why did the Jomon people build a stone circle here? Archaeologists can’t find any traces of human life that date back to before the stone circles were created, and can only find evidence of pitfalls used for hunting. If this was an area for hunting, why would the Jomon people choose it for the stone circles?

The theory goes that the Jomon people chose an area that was not the territory of any village, so it was a “neutral zone”. By doing this, the process of building the stone circle could become a collective inter-village project without any conflict. This could explain how the stone circle grew to be this large.

Another theory goes that this spot was chosen because you can see the pyramid-shaped Mt. Kuromata from here, a place filled with legends. What do you think? Why did they choose this place?
