Blessed with nature where crested ibis soar in the sky, Sado Island boasted abundant mineral resources. From the 17th to the middle of the 19th century, mines were developed at full scale, making it widely known as the gold-producing island.
The “Sado Island Gold Mines” was valued as an exceptional example in the Asian context of the continuity of advanced manual mining and smelting technology in a period when mechanization was being introduced elsewhere, and it was inscribed as a UNESCO World Cultural Heritage Site on July 27, 2024.
