Justification of Red List category
This species is listed as Endangered, thus is perceived to be at a very high risk of extinction, because it has a very small population size of only 100-300 mature individuals. It was formerly considered to be Critically Endangered because of a declining population trend, but this has now been stabilised because of the protection of forests on Okinawa, and successful programmes to control invasive mongoose.

Population size: 75-400, 100-300 mature individuals
