The Chojak原 Site, located within Miyama Park in Itoigawa City, Niigata Prefecture, is one of the largest settlement remains in the Hokuriku region, dating back to the Jomon period between approximately 5,500 and 4,000 years ago. This site served as a vital hub for the production and distribution of stone tools, particularly stone axes and the highly prized jadeite (jade) processed from stones found in the Hime River. Situated on a plateau about 90 meters above sea level and 2.5 km from the coast, this archaeological site is a crucial location for understanding how ancient people utilized their natural environment to build an advanced stone tool culture.
The history of this site traces back to the mid-Jomon period. The Hime River basin is globally renowned as a source of precious jadeite, and the Chojak原 Site was a key point in its distribution network. The process of crafting stone tools and jade ornaments and transporting them to various regions formed the foundation of life here. The 'Chojakerahara Site Park,' developed to preserve and showcase this history, features reconstructed displays based on excavation results, providing tangible evidence of the social structures and technological standards of the era.

The Chojak原 Site and the Chojak原 Archaeological Museum offer the following exhibits and facilities:
The Chojak原 Site Park is set within a lush natural environment, offering different scenic views depending on the season. For those wishing to study the historical remains closely, visiting during bright daylight hours is highly recommended. The museum exhibits are an excellent way to learn about ancient culture regardless of weather, making it a great option for sightseeing during rainy days or hot summer months. You can also enjoy the changing seasonal beauty of the surrounding flora, such as the lily species.
The Chojak原 Archaeological Museum offers more than just viewing; it provides programs to connect with Jomon culture. Specifically, 'Jomon Experience' programs allow visitors to feel closer to the technology and lifestyle of the era. Additionally, specialized knowledge can be gained through related facilities like the Archaeology Salon and the Jadeite Culture Research Institute.
The site is located within Miyama Park, allowing visitors to enjoy a stroll through the park alongside the historical exploration. It is closely related to other geological and historical sites in Itoigawa, such as the Fossa Magna Museum.
