Adults have darker fur than infants and juveniles.Adult males have a special feature called a “momoware” (split peach) which parts their hair in the center from right to left.
Females bear a single offspring between March and May, every two years.Troop size is generally less than 50 individuals.
The Yakushima macaque population in Yakushima Island lies at the southern limit of Japanese macaque's distribution. The current population is estimated to be somewhere between 9,504–18,890 animals, according to a survey completed in 1999.
According to the Ministry of the Environment's Red List of endangered species, the Yakushima macaque was judged “a rare species” in 1991 and “a quasi-endangered species” in 1998. But it was removed from the list in 2007 due to an increase in population.A species of Japanese monkey also inhabited Tanegashima, an island near Yakushima, until the 1950s, when it became extinct. Whether those monkeys were Hondo macaques or Yakushima macaques is unknown.
