Site location and context
Hahajimaretto islands are located 1,050 km south of Tokyo metropolitan area. It consists of Hahajima, Mukojima, Hirashima, Anejima, Imotojima, Meijima and others. Hahajima, the largest island, is about 20.21 km, the highest point is Chibusayama at about 463 m high. The island has a perimeter of about 58 km, and most are steep cliffs. Although main islands had once been settled before the World War II, all islands became uninhabited by the time of the reversion of Ogasawara islands to Japan in 1968. With this history, lost forests by the plantation have been rather recovered. However, Bischofia javanica, which was planted for firewood before the war is an invasive species competing with native vegetation since 1980, so the AKAGI (Bischofia javanica) extermination project has been going on.
