Sado is Japan’s sixth-largest island and depends mainly on fishing and agriculture. The island’s Tori Forest Park had been selected for the successful reintroduction of Crested Ibises into Japan –a bird that was down to what was believed to be a total world population of 12 birds in 1981. At that time the last five wild ibises found in Japan were taken into captivity on Sado and both Japan and China cooperated in a breeding programme for these birds. Fortunately the work has paid off and released Crested Ibises successfully nested in the wild again in 2012. Another attraction is the Sado Gold Mine. The adventurous can descend into the deep tunnels to see the conditions under which gold was extracted for almost 400 years.
