Ōkunoshima

After this story: "Tame bunnies have escaped from the now abandoned poison gas factory" and/or this one: "In the 1970's children did a project to set out tame bunnies in the wild", you might think this island has a small number of bunnies that are strangely attracted to humans. You'd be wrong. This island is lined with thousands of tame bunnies. All of them eager to get food off you, and they'll even eat from your hand. Such meek prey, and no predators. Ah, the good life.
