Takasakiyama Natural Zoological Garden
In the northwest of Oita, Mt. Takasaki is home to over 1,200 wild Japanese macaques that freely roam the hills. It isn't a zoo in the conventional sense; it is a place where the monkeys who live on the mountain can come to play and be fed. Follow one of the walking paths around the park to catch a glimpse of the monkeys playing, eating, and relaxing.
For a small fee you can ride a monorail to the area where monkeys congregate. There is an indoor play area for children, a small museum on the history of the zoo, souvenir shops and a cafe.
