I came across the free to enter zoo in Yokohama whilst wondering around the park. This zoo hosts various animals such as tigers, lions, chimpanzees and giraffes, personally I was quite disappointed with the standard of care and general sanitation, but you cannot expect much as it is free to visit. If you want to understand these beautiful creatures a bit better this is a good place to go to. I spent about an hour here walking around and noticed the giraffe was almost begging for food, as none was in the enclosure so I gave him some sticks from just outside.
