In the Japanese island of Ōkunoshima is known as the Rabbit Island for its huge population of wild bunnies.

Editor’s update: During WWII, Okunoshima, now known as Rabbit Island, had a secret Japanese Imperial base used for lethal gas production. The bunnies may have been released by workers after the plant closed or by schoolchildren who visited the island in 1971, but however it happened, the bunnies have bred and spread over the whole island. Now, visitors flock to the island to feed the veritable herds of wild bunnies that live there.
