The Japanese macaque (; Macaca fuscata), also known as the snow monkey, is a terrestrial Old World monkey species that is native to Japan. They get their name “snow monkey” because some live in areas where snow covers the ground for months each year – no other non-human primate is more northern-living, nor lives in a colder climate. Individuals have brown-grey fur, pinkish-red faces, and short tails. Two subspecies are known.In Japan, the species is known as Nihonzaru (ニホンザル, a combination of Nihon 日本 “Japan” + saru 猿 “monkey”) to distinguish it from other primates, but the Japanese macaque is very familiar in Japan, so when Japanese people simply say saru, they usually have in mind the Japanese macaque.
