Chimpanzee Takeru (18 years old) was found dead on the morning of April 2nd.
Takeru was kept and exhibited together with two male chimpanzees (Pihske, 22 years old, and Kohsuke, 15 years old) at the Chimpanzee Museum.

Although there have been fights between chimpanzees and related injuries in the past, it has been observed that from around January 2024, "Pihske" was becoming more persistent when attacking "Takeru".

Since around March 25th, his energy level and appetite have been declining, but he has been moving between his bedroom and the indoor exhibit area with two other dogs, and the same thing happened the day before.

Then, on the morning of April 2nd, zookeepers found him dead on the floor of an indoor exhibition hall.
An autopsy determined that he died from traumatic shock caused by the fight.
