Time Out says
Japan’s oldest zoo, established in 1882, is also Tokyo’s most popular, thanks mainly to its central location in Ueno Park and its range of beasts, including a giant panda and a Sumatran tiger. You’ll find the panda in the eastern section, along with elephants, lions, gorillas, sea lions and assorted bears. Don’t be discouraged by the crowds, though; the western section across the bridge is less busy and offers opportunities to interact with animals in a petting zoo and to watch a huge alligator relaxing in the reptile house.
