The 2013 KAIYODO Japanese macaque walkaround

Known as the snow monkey, the Japanese macaque (Macaca fuscata) is the most northerly occurring non-human primate. In general, macaques are strong-limbed, medium-sized monkeys with stout bodies. This species has long, dense fur which is brown to grey in colour. The thick fur contrasts with the naked skin of the face and rump, which is red in adult Japanese macaques. It has long whiskers, a beard and a relatively short tail. The male Japanese macaque is larger than the female.
In Japan, they are known as Nihonzaru (Nihon "Japan" + saru "monkey") to distinguish it from other primates, but Japanese macaque is very familiar monkey in Japan , so when Japanese people simply say Saru, they usually have in mind the Japanese macaque.
The Japanese macaque is diurnal, variably spending the daytime foraging, travelling, socially interacting and resting. It is an unfussy eater and its diet varies with habitat and season. Typically, it feeds on leaves, fruit, berries, seeds, small animals, insects and even fungi.
With its thick coat, the Japanese macaque can survive winter temperatures of -15 degrees Celsius. However, it is probably most well known for its habit of sitting in natural hot springs in order to escape the winter extremes. Japanese macaques are also thought to display ‘culture’, where a learned behaviour is passed through the troop. The most famous example of this is where a young female in a provisioned troop began washing potatoes and wheat in sea water. This behaviour was transmitted to other members of the troop and has since been passed on to subsequent generations.

KAIYODO made several Japanese macaques in the past. Nevertheless, the 2013 one is a very good addition IMHO.
