Uotsuri-jima Island in the Senkaku Islands, southwestern Japan is a small island characterized by very valuable biota with high endemicity which has formed over a long period of isolation. The ecosystem on this island is under the risk of total destruction because of the presence of domestic goats, Capra aegarus, were introduced in 1978 by a private political party in Japan and increased to more than 300 individuals. This problem is made more difficult due to the territorial conflicts over the Islands by Japan, China and Taiwan.
