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. "Bonin Islands" is the common name in English for Ogasawara Guntō, from the Japanese word bunin (an archaic reading of 無人 mujin), meaning "no people" or "uninhabited".
