Okunoshima Island is located in Japan’s Inland Sea. It is referred to as Rabbit Island because of the numerous feral (and rather tame) rabbits that roam the island.
Rabbits everywhere. Okunoshima Island seems like a rabbit lover’s paradise. However, the museum on the island reveals a dark past. Okunoshima was home to a poison gas factory during World War II. Stories vary as to why the rabbits are on the island. Some say the rabbits were test subjects but were set free after the factory closed. Others say school children released the original rabbits, and because there were no natural predators, the population exploded.
