The Japanese Macaque (Macaca fuscata), also known as the Snow Monkey, is a terrestrial monkey native to northern Japan. They are said to be the most northern-living non-human primate. The Japanese Macaque has gray-brown fur, a pink face and hands, and a short tail. They eat mainly fruit and vegetation, but are also known to eat insects and small vertebrates.

Japanese macaques are highly intelligent. They are the only animals other than humans that are known to wash their food before eating it. These monkeys are perhaps most famous for the amount of time they spend relaxing in hot springs during the cold winter months.
