Jade Coast (Hisui Coast)

The Jade Coast in Itoigawa City, Niigata Prefecture, represents one of the world's oldest jade-producing regions, with archaeological evidence showing jade tools crafted 7,000 years ago during Japan's prehistoric Jōmon period. Jade holds special significance as Japan's national stone, and this coastal area continues the ancient tradition of jade formation through natural geological processes.

Located on Japan's west coast between Niigata and Toyama Prefecture, Itoigawa sits nestled between mountains and the Sea of Japan. The gravel beach serves as a natural collection point for jade stones carried downstream from the Kotakigawa Jade Gorge, a designated natural monument, making it Japan's largest jade production area. The coastline is part of the Itoigawa UNESCO Global Geopark, recognized for its unique geological significance.

Visitors can experience the thrill of jade hunting along the shoreline, where luck may reward them with genuine jade stones that have traveled from upstream sources over countless years. The area offers stunning coastal scenery with views across the Sea of Japan, complemented by the dramatic mountain backdrop. The nearby National Route 8, known as Tara-jiru Kaido, features local specialty cod soup restaurants, providing authentic regional dining experiences.

Transportation to Jade Coast is accessible through multiple routes. The Hokuriku Shinkansen connects Tokyo Station to Itoigawa Station in approximately 2.5 hours (¥11,000), with the beach reachable by a 25-minute walk from the station or by taxi. Alternatively, visitors can take local trains to Echigo Oshiage Jade Coast Station, located just a 5-minute walk from the jade hunting area. Free parking is available at multiple locations for those traveling by car. Beach access is free with no admission charges, making it an accessible destination for all travelers.
