Iwatayama Monkey Park is a commercial park located in Arashiyama in Kyoto, Japan. The park is located atop Mount Arashiyama, on the opposite side of the Ōi River of the train station. It is inhabited by a troop of over 120 Japanese macaque monkeys. The animals are wild but can be fed by the staff and visitors with food exclusively purchased at the site. The main reason why these wild macaques choose to stay in the park, is so that they can feed on the food given by the staff.
