小笠原群島
The Bonin Islands are about 1000 km south of Honshu, Japan's largest island, and north of the Tropic of Cancer. The Bonin islands form three clusters, Mukojima, Chichijima, and Hahajima, composed of one larger island and several smaller ones. Chichishima, the largest island, and Hahajima, the second-largest, are the only inhabited Bonin islands. The highest point on Hahajima is 326 m, and Chichishima's highest point is 462 m. The Bonin Islands have sea cliffs along the shore. The center of Chichishima and other islands in the group (Ani-shima and Ototo-shima) is rolling plateau, while Hahajima has steep ridges and Mukojima is mostly flat.
