Sado Island Gold Mines
Sado Island has mined gold, silver, and copper mines since ancient times, and in the first half of the seventeenth century, it was home to one of the largest gold mines in the world. In July 2024, the Sado Island Gold Mines were inscribed on UNESCO’s World Heritage List.
Even after mechanized mining had become the norm worldwide, Sado Island continued to produce large amounts of high-quality gold, mined by traditional unmechanised that did not rely on machines. The mines and remains here still bear witness to this local history, leading to its World Heritage designation. One of the component part, the Aikawa-Tsurushi Gold and Silver Mine, was among Japan’s largest gold and silver mines. Here, workers mined these precious metals by hand for over 250 years, from the sixteenth through mid-nineteenth centuries. At the Historic Sado Gold Mine, a portion of the mine’s tunnels are now open to the public, where visitors can see vestiges of the hand-carved mines and recreations of what mining work looked like at the time, as well as the Doyu-no-Warito Opencut Site, where a mountain appears to have been split in half by gold mining.
