Natural Habitat Conservation Areas are one element in a network of complementary protected area systems. Others include Wilderness Areas and Nature Conservation Areas under the Nature Conservation Law; Natural Parks under the Natural Parks Law; Wildlife Protection Areas under the Wildlife Protection and Hunting Law; Natural Monuments and Special Natural Monuments under the Law for the Protection of Cultural Properties 1950; Nature Conservation Forests under the National Forest Management Bylaw; and Protected Waters under the Preservation of Fisheries Resources Law. Areas are also protected in accordance with three international programmes: the World Heritage Convention (see Yakushima, Shirakami-Sanchi, Shiretoko, and Ogasawara Islands); Man and the Biosphere Programme (see Yakushima, Mount Ōmine/Mount Ōdaigahara, Hakusan, and Shiga Kōgen); and the Ramsar Convention (see Ramsar Sites in Japan).
