About this spot
The Sado Gold Mine, on Sado Island in Niigata Prefecture, is one of Japan's largest mining heritage sites, which continued to produce gold and silver for over 400 years. In 2024 it was registered as a UNESCO World Heritage Site as "The Sado Island Gold Mines," attracting renewed attention. Within the vast grounds, you can tour the "Sodayu Tunnel," which recreates the hand-digging of the Edo period with life-size figures, and the "Doyu Tunnel," which preserves its appearance as an industrial heritage site of modernization from the Meiji era onward. In particular, the "Doyu no Warito," an open-pit mining site from the Edo period, is a mystical sight in which a huge mountain appears split into a V shape, and it has become a popular photo spot. The museum's experience of grabbing a real 12.5 kg pure gold bar is also very popular. The tunnels stay a cool 10 degrees Celsius or so year-round, so sightseeing is comfortable even in summer. Whether you soak up history alone or enjoy the experiences as a family, this is the island's top attraction, where you can feel the weight of history and an overwhelming scale.
