The JapaneseRed List is the Japanese domestic counterpart to the IUCN Red List of Threatened Species. The national Red List is compiled and maintained by the Ministry of the Environment, alongside a separate Red List for marine organisms. Similarly drawing on the relevant scientific authorities, NGOs, and local governments, the Ministry of the Environment also prepares and publishes a Red Data Book that provides further information on species and habitats.
