A baby monkey in Japan has captured hearts around the world after videos of him being bullied by other monkeys and rejected by his mother went viral last week.

Punch, a Japanese macaque, was born last July at Ichikawa zoo. He has drawninternational attention after zookeepers gave him a stuffed orangutan toy after he was abandoned by his mother.

Without maternal guidance to help him integrate, Punch has turned to the toy for comfort. He has been filmed multiple times being dragged and chased by older Japanese macaques inside the enclosure. Early clips showed him wandering alone with the toy after being pushed away by other monkeys, and clutching it tightly while being harassed. Viewers were briefly relieved when later videos emerged of another monkey grooming and comforting him.

However, just days later, new footage showed Punch once again being targeted – this time dragged aggressively in a circle by a much larger monkey before running to hide behind a rock, hugging his toy.

The videos have prompted questions about why monkeys abandon their babies. Alison Behie, a primatology expert at Australian National University, said such abandonment is unusual but can occur under certain conditions, citing “age, health and inexperience” as possible factors.

Behie said: “In Punch’s case, their mother was a first-time mother, indicating inexperience.

“Zookeepers also suggest Punch was born during a heatwave, which would be a high stress environment. In environments where survival is threatened from outside stress, mothers may prioritise their own health and future reproduction rather than continue to care for an infant whose health may be compromised by those environmental conditions.”

Following Punch’s abandonment, zookeepers introduced the stuffed orangutan after trying alternatives, including rolling towels to different thicknesses for him to cling to.

“Baby Japanese macaques immediately cling on to their mother’s body after birth to build muscle strength. They also get a sense of security through holding on to something. However, because he had been abandoned, Punch had nothing to grip on to,” the zookeeper Kosuke Shikano said.

“We thought that [the toy] looking like a monkey might help Punch integrate back into the troop later on,” he added.

Referring to the stuffed orangutan, Behie said: “The toy Punch has may be serving as an attachment figure, especially given they are six months old so likely still need to be nursed.”

Behie added that the behaviours of other monkeys towards Punch “isn’t bullying or any abnormal behaviour, but regular social interaction”.

According to Behie, Japanese macaques have strict matrilineal hierarchies, where higher-ranking families assert dominance over lower-ranking ones. Even with his mother, Punch would probably still face this aggression, she said.

However, Behie said that without his mother “Punch may not develop the appropriate subordinate responses to show they submit to the dominance, which could have ongoing implications for the way they integrate into the group as an adult”.

In recent days, the zoo has experienced a surge of visitors hoping to catch a glimpse of Punch. In response, officials have enforced stricter barriers around the enclosure and urged visitors to remain quiet, avoid using stepladders or tripods for photography and limit prolonged viewing.

Carla Litchfield, a conservation psychologist at Adelaide University, pointed to the intelligence of Japanese macaques and as a result, their popularity for biomedical and neuroscience experiments in Japan. She also said that macaques were culled in Japan because of their habit of raiding crops.

“This story about Punch highlights the impacts of habitat loss, climate change, zoo animal welfare, and the power of social media to connect people to animals,” Litchfield said. “However, hopefully the millions of social media likes, and attention won’t exacerbate the problem of illegal trade in infant monkeys for the exotic pet trade because everyone thinks baby monkeys are cute and would make a great pet.”

“Monkeys grow up quickly – Punch will be an adult in four years – and people no longer find them cute and manageable. Monkeys belong with other monkeys. They are social beings and need to be with their own species to thrive mentally and physically.”

Punch isn’t the first zoo animal to garner global fascination – Moo Deng, the young pygmy hippo in Thailand captured hearts in 2024 with her stubborn attitude and star quality.
