Capybaras are typically described as the “world’s biggest rodent,” but their murine roots are rarely spoken of in Japan, where they are arguably the country’s favorite animal. According to recent data from the Japanese Association of Zoos and Aquariums, the number of capybaras kept in facilities around Japan increased to 422 in 2016 from 125 in 2006, far outstripping the growth in the number of animal parks. Capybaras, which are native to South America, can now be found in 59 parks across Japan, according to the association, up from 21 in 2006.
