- Okinawa Red List of Threatened Species: Critically Endangered
- Japan Red List of Threatened Species: Vulnerable
- Up until recently, Oryzias latipes found in Okinawa prefecture was thought to be introduced from Kyushu, Japan long time ago. DNA analysis found out that the population found in Okinawa prefecture is endemic. Habitat loss due to river development and environmental degradation, and population reduction due to competition with introduced species such as guppies, mosquitofish and swordtails that have similar feeding behaviors. Another concern of this species is possible genetic disturbances caused by crossbreeding with introduced ricefishes from different areas.
