Sado Gold and Silver Mine, Toward World Heritage

On Sado Island, which is off the coast of mainland Japan, there were some large-scale mines which had been developed from the middle of the 16th century, and those remains are preserved in good condition.
Sado Gold and Silver Mine is now aiming to be inscribed on the UNESCO World Heritage List.
In November 2010, Sado Gold and Silver Mine was inscribed on Japan's World Heritage Tentative List, under the title of "The Sado Complex of Heritage Mines, Primarily Gold Mines".
