Nashikubo site

Historic Site/Japan Heritage
This is the closest village to the obsidian mine. Pursuing good-quality obsidian, Jomon people converged on this area in numbers, making it a center for East-West cultural exchanges. It is clear that "brand" products such as amber, jade stone, and obsidian were traded here. This tells us that this was an area of cultural exchange linking the Sea of Japan with the Pacific Ocean. This site is a nationally designated Historic Site.
