basic information

Sado Island was the largest producer of gold and silver in Japan during the Edo Period. As a result, the Tokugawa Shogunate built the Sado Bugyosho (Magistrate's Office) in order to directly control the island and its mines.

The Sado Bugyosho served as the center of government on the island, and was made up of both governmental offices and gold production facilities. It was headed by a magistrate who was appointed by the shogun and charged with overseeing the mines, as well as handling public administration and judicial matters.

The buildings of the Sado Bugyosho have been destroyed by fire and subsequently rebuilt numerous times. Most recently, a few of the buildings, including the governmental offices, the magistrate's residence, a refinery, and a storage facility were completely reconstructed and opened to the public in 2000 on the occasion of the 400th anniversary of the gold mine.
