The Japanese macaque (/məˈkɑːk/; Macaca fuscata), also known as the snow monkey, is a terrestrial Old World monkey species native to Japan. They get their name "snow monkey" because they live in areas where snow covers the ground for months each year – no other nonhuman primate is more northern-living, nor lives in a colder climate. Individuals have brown-grey fur, red faces, and short tails. Two subspecies are known.
