Tourists flock to Japan’s Rabbit Island just to be attacked by dozens of bouncing bunnies.

Visitors are mobbed the moment they reach into a bag or rustle anything that sounds like paper.

Officials have banned cats and dogs from the island to keep the rabbits safe.

Many rabbits were use as test subjects when the island it was a chemical warfare testing ground, but it is expected that all of them were killed when the factory was demolished - so no one really knows where all these rabbits came from.

There’s a rumor that a teacher once brought some rabbits to the island for school children to play with, and they then multiplied like, well, bunnies.

Though nobody knows for sure, the tourists don’t seem to care. And the rabbits are totally cool with it. Obvi.
