Every year in Japan, animals escape from zoos in a planned exercise. Except they aren't really animals, they're humans in animal costumes. And they aren't really escaping, they're part of an annual drill to train staff on what to do when a real animal does. While funny to watch, escaped animals are no joke in a country known for earthquakes.
Director of Tama Zoological Park, Yutaka Fukuda, told Metro in 2015:
‘In the event of a big earthquake, a tree could fall on a cage, or many other things could occur that may lead to an animal escape.
‘We think it is very important, and it is our responsibility to carry it out with seriousness.’
Look for the real lions, their reactions to the drill are priceless.
