Artifacts included a large amount of Jōmon pottery, stone tools, lacquer products and seeds.

However, during the 1980 survey a ring of wooden columns forming a timber circle was discovered in conjunction with a land development project.

In the subsequent survey, a total of 347 foundations of large pillars with a diameter of 30 to 85 centimetres arranged in timber circles were found.

[2] The site is now an archaeological park with wooden pillars restored to a height of 2 meters erected in a ring, recreating the situation at that time.

In addition, in the permanent exhibition room of Kanazawa Jōmon World, a circular wooden pillar row has been restored indoors.
