Ramat Gan Safari Mourns Sudden Loss of Five-Year-Old Orangutan Tokyo
The Ramat Gan Safari mourns Tokyo, a five-year-old orangutan who died suddenly from brain necrosis. Her parents were allowed to say goodbye in a poignant moment highlighting animal grief.

The Ramat Gan Safari is mourning the loss of Tokyo, a five-year-old female orangutan who died suddenly from a mysterious brain necrosis. Her birth five years ago was a major milestone for the safari, as she was the first orangutan born at the facility in 11 years, bringing immense joy to the staff and visitors.
Tokyo was known for her vibrant, curious, and playful personality. She spent her days in the enclosure with her parents, Tana and Rahamim, along with other primates. Keepers recalled how she loved playing with water, swinging from ropes, and constantly seeking interaction with the human staff who had watched her grow up from the moment she was born.
Sudden Illness and Grief
Her condition deteriorated rapidly after she began showing signs of distress and weakness. Despite emergency veterinary intervention and resuscitation attempts at a veterinary hospital, Tokyo passed away. The staff made a conscious decision to allow her parents to see her body, ensuring they could understand her death and say their proper goodbyes.
"It was very important for us that they be able to say goodbye and understand that she had died," said Danielle Degani, a primate keeper. Tana entered the enclosure, lifted the blanket to look at Tokyo, and quickly left, while Rahamim watched from a distance. Experts note that animal grief and mourning share striking similarities with human emotional responses during loss.
Conservation Significance
Orangutans are critically endangered in the wild due to rampant deforestation in Borneo and Sumatra. The Ramat Gan Safari participates in the European Endangered Species Programme (EAZA) to protect the species, making Tokyo's untimely death a significant loss not only for the local staff but for global conservation efforts as well.
