Mount Takasaki, the mountain on which Takasakiyama Natural Zoological Garden is located, borders Ōita City, Beppu, and Yufu.
The parking lot for the zoological garden is located along Japan National Route 10 between Ōita City and Beppu and is shared with the Oita Marine Palace Aquarium.
[1]In 1952, Ōita City Mayor Tamotsu Ueda, concerned about the damage that the Japanese macaques were doing to farms surrounding Mount Takasaki, sought to gather all of the monkeys into one location.
Takasakiyama made news in 2021 when Yakei, a female macaque, became the leader of Troop B.
Visitors are requested not to tease or touch the monkeys, not to make eye contact with them, and not to feed them.
