Site description Mukojimaretto islets located in the north of Ogasawaragunto chain islands on the Pacific Ocean which are about 900-1,100 km south of Tokyo metropolitan area, consist of Kitanoshima, Mukojima, Nakoudojima, Yomejima and other islets. The largest Mukojima is about 2.57 km2, and the highest point is at Nakoudojima which is about 155m high. They are small and flat islets. Most forests have been lost to vegetation destruction caused by feral goats, and resulted in erosion. Since the latter half of 1990s feral goats have been exterminated, but there are still some goats that remain on the island. A vegetation recovery project has progressed at the remaining forests.
