A lush forest gives way to the rocky entrance to the Sado Goldmines in Hiroshige’s depiction of Sado Province. Miners dot the foreground as the mountainside opens to three mining shafts, each internally reinforced with wood. While the island had been known for its gold since the 12th century, the gold from Sado became an important source of wealth for the Tokugawa shogunate during the Edo period. Though the local economy prospered from the mines in the 17th century, by Hiroshige’s time the veins were running dry and the working conditions had significantly declined. The mines finally closed in 1989. Today, the former Sado Province corresponds to Sado Island in Niigata Prefecture.
