Discover the mysteries of Sado Island, vying to be a World Heritage Site.
Once home to a prosperous gold-mining community, this huge island on the Sea of Japan fueled the Japanese economy for over 400 years. The Aikawa Gold and Silver Mine, now opened to the public as the Sado Gold Mine, was heavily mined for its rich deposits since the beginning of the 17th century. It quickly became one of the largest gold mines in the world and was in continual use until the 1980s.
