The Ogasawara Islands, also known as Bonin Islands, belong to an archipelago of about 30 islands. The islands were formed by an ancient underwater volcano and there are many sheer cliffs along the coast.
The archipelago is situated about 1'000 kilometres in the south of Tokyo. It includes the three active volcanic islands Kita Iwo-jima, Iwo-jima and Minami Iwo-jima.
Chichi-jima is the main island of the Ogasawara Islands. The mountainous island covers an area of 23.8 square kilometres. Its highest summit is the Chūō-zan at 318 metres.
The Ogasawara Nationalpark consists of three groups of islands – Muko-jima (Groom), Chichi-jima (Father), Haha-jima (Mother) and Kita Iwo-jima of the Kazanretto Islands. The other two Kazanretto islands Iwo-jima and Minami-Iwo-jima Islands are not included in the park.
The Ogasawara Islands were inscribed upon the UNESCO World Heritage List in the year 2011.
