The Bonin Islands, also known as the Ogasawara Islands(小笠原群島,Ogasawara Guntō), are an archipelago of over 30 subtropical and tropical islands, some 1,000 kilometres (540 nmi; 620 mi) directly south of Tokyo, Japan. The name "Bonin Islands" comes from the Japanese word bunin (an archaic reading of 無人 mujin), meaning "no people" or "uninhabited". The only inhabited islands of the group are Chichi-jima (父島), the seat of the municipal government, and Haha-jima (母島), which includes Ogasawara Village.
