Idojiri site is a Middle Jomon (c. 3,500?2,500 BC) settlement site. It forms the center of the Idojiri site complex, which includes many other sites including Sori, Toudomiya, and Tonai sites. Survey and excavation research at Idojiri began in 1958 and included independent scholars, school teachers, and local residents. The experiences fostered a local residents’ movements to preserve archaeological sites. Idojiri also stimulated the Jomon Plant Cultivation Hypothesis, promoted by the leading independent scholar of the Central Highlands, Fujimori Eiichi (1911?1973), who demonstrated skepticism towards wider accepted theory that the Jomon period was a hunter-gatherer-fisher society. Idojiri site was designated National Historic Site in 1966 and was developed into historic park with a reconstructed pit dwelling. Artifacts found from this site are exhibited at the Idojiri Archaeological Museum.
