Macaca fuscata, commonly known as the Japanese macaque or snow monkey, is a species of primate native to Japan. They are known for their thick fur, which helps them survive in cold climates, particularly in the snowy regions of Honshu and Shikoku. These monkeys are highly social and live in troops, exhibiting complex social behaviors. Japanese macaques are omnivorous, feeding on a varied diet that includes fruits, seeds, and insects. They are famous for their unique habit of bathing in hot springs during winter, a behavior that has attracted significant attention from researchers and tourists alike.
