Japanese macaques — the world's most northerly non-human primates — face welfare challenges from agricultural conflict, provisioned tourism sites, and climate-related habitat change.
Wild Japanese macaques experience welfare harms from snare injuries that cause prolonged pain and death, crop-raiding conflicts with humans that result in lethal control, and the chronic stress of living in fragmented agricultural landscapes. Provisioned tourist sites, while economically supported, create unnaturally high group densities that increase aggression, disease transmission, and food competition. Evidence from provisioned sites shows elevated stress hormones and altered dominance behaviour. Coexistence strategies — electric fencing to protect crops, aversion conditioning, and non-lethal deterrents — reduce conflict-related killing and the associated suffering.
