Rabbit Island, or Okunoshima, is occupied by thousands of wild rabbits, and nobody knows how they got there.
One theory is that the rabbits are somehow related to Japan's dark history; after all, between 1929 and 1945, Japan produced over 6,000 tons of poison gas on Okunoshima, and test rabbits were brought to the island.
Another theory is that in 1971, students brought eight rabbits to Okunoshima, and these furry creatures just kept breeding.
Rabbit Island is a short ferry ride from the mainland. Tourists can learn more about Japan's role during WWII from the poison gas facilities there, but the island also has camping grounds, beaches, and a small golf course.
