Japanese macaques are adaptable primates that fare relatively well in captivity when social and environmental needs are met. Key welfare considerations differ from tropical primate species.
Japanese macaque welfare in captivity benefits from their thermoregulatory flexibility — they do not require heated enclosures in temperate climates and can access outdoor spaces year-round. Social complexity is the most important welfare consideration; appropriate group composition with sufficient females and managed male integration prevents the infanticide and severe aggression that destabilise groups. Enrichment that supports cultural learning and manual dexterity reflects the species' natural cognitive repertoire.
