Guide
The Chojakahara Site, located within Miyama Park in Itoigawa City, Niigata Prefecture, is one of the largest settlement ruins in the Hokuriku region, dating back to the Jomon period (approximately 5,500 to 4,000 years ago). This site served as a crucial hub for the production and distribution of stone tools, particularly stone axes and jadeite (jade), utilizing resources from the Hime River. Situated on a plateau about 90 meters above sea level and 2.5 km from the coast, the site provides vital archaeological evidence of how ancient people utilized the natural environment to build a sophisticated stone tool culture.
The history of this site reaches back to the mid-Jomon period. The Hime River basin is globally renowned as a source of high-quality jadeite, and the Chojakahara Site was a key center for its trade. The processes of processing stone tools and jade ornaments for distribution across various regions form the foundation of the life lived here. The 'Chojakahara Site Park,' developed to preserve and showcase these findings, features reconstructed exhibits based on excavation results, offering a tangible look at the social structures and technological standards of the era.
