Itoigawa Geopark, designated a UNESCO Global Geopark, sits at the dramatic meeting point of the Fossa Magna, a major geological fault line dividing Japan’s main island, creating a landscape of striking coastal cliffs, mountains and unique rock formations. The area holds particular significance as the site where jade (hisui) was first identified in Japan in the 1930s, later found to have been quarried and worked by ancient Jomon-period peoples thousands of years earlier, and visitors can search for jade fragments along designated beaches or visit dedicated museums exploring the region’s geology and jade heritage.
