Kitazawa Flotation Plant Ruins
北沢浮遊選鉱場跡
A stepped ore-processing plant ruin built in the early Showa era. Its ivy-covered concrete walls look like a “castle in the sky”, and it is lit up at night.
The Kitazawa Flotation Plant was built in 1937, when it was billed as the “Number One in the Orient”. It was a facility for separating gold and silver from ore. Only its stepped concrete walls remain today, covered with ivy and other plants, earning it the nickname “Castle in the Sky of Sado”. Nearby are the ruins of a 50-meter-diameter thickening tank and the Kitazawa Thermal Power Station. The ruins are open for free viewing, and you can look up at them from the plaza below. During the peak summer season the site is lit up at night. It is located in Aikawa town, about 10 minutes’ walk from the Sado Magistrate’s Office.
