Tokyo: Three female lions at Tokyo's Tama Zoological Park died of suspected heatstroke during Japan's extreme weather. The lionesses, aged three to fifteen years, died between July 28 and August 2. Zoo authorities claimed 10 of the park's 16 lions have been exhibiting signs such as loss of appetite and lethargy since mid-July, when temperatures and humidity rose. Veterinary exams and autopsies revealed severe dehydration and various organ failure, prompting doctors to infer heatstroke as the reason.

According to the zoo, while lions are naturally suited to hot climes, Japan's combination of intense heat and heavy humidity is significantly more difficult than the dry conditions of their original African homes. Officials said the sudden spike in temperatures following the rainy season likely added stress to the animals, making them more prone to heat-related sickness.

Following the deaths, the zoo has stepped up efforts to preserve the remaining lions. Water is sprayed more often to keep enclosures cool, ventilation has been enhanced, and spot air conditioners have been installed. Several lions are still being closely monitored by veterinarians, with some receiving treatment for heat-related illnesses.

The incident occurred as Japan was experiencing one of its warmest summers on record, with temperatures reaching about 40°C in some locations. In recent weeks, thousands of individuals have been hospitalised due to heatstroke, illustrating the extreme weather's widespread impact.
