List of amphibians of Japan

This list of amphibians recorded in Japan is primarily based on the IUCN Red List, which details the conservation status of some ninety-four species. Of these, four are assessed as critically endangered (the endemic Amakusa salamander, Mikawa salamander, Tosashimizu salamander, and Tsukuba clawed salamander), twenty-seven as endangered, fourteen as vulnerable, eleven as near threatened, and thirty-eight as of least concern.

According to statistics accompanying the 2020 Japanese Ministry of the Environment (MoE) Red List, ninety-one species and subspecies are to be found, but the conservation status of only sixty-seven is detailed. Of these, five taxa are critically endangered from a national perspective, twenty are endangered, twenty-two vulnerable, nineteen near threatened, and one data deficient.

As of January 2023, for their protection, forty-one species have been designated National Endangered Species by Cabinet Order in accordance with the 1992 Act on Conservation of Endangered Species of Wild Fauna and Flora.
