The rabbits have taken over on Okunoshima Island, turning it into a tourist attraction. During World War II the island was used as a poison gas facility, and its existence was so secret that local residents were told to keep away. It was even removed from maps. But the bunnies, descendants of lab animals, soldiered on. Now often called Usagi Jima or “Rabbit Island,” it attracts visitors who come to the feed the bunnies on the beach and enjoy the island’s tourist facilities, which include a resort, six-hole golf course and camping grounds.
