List of reptiles of Japan

This list of reptiles of Japan is primarily based on the IUCN Red List, which details the conservation status of some one hundred species. Of these, five are assessed as critically endangered (the hawksbill turtle and yellow pond turtle and the endemic Toyama's ground gecko, Yamashina's ground gecko, and Kikuzato's brook snake), ten as endangered, twelve as vulnerable, thirteen as near threatened, fifty-eight as of least concern, and two as data deficient.

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