Okunoshima is a small island, accessible by ferry, in Japan’s Inland Sea. The island often called Usagi Jima – “Rabbit Island” – is famous for its rabbit population, which has taken over the island and made it a tourist attraction. People go there to feed the animals as well as to enjoy the tourist facilities, which include a resort, six-hole golf course and camping grounds.
From 1929 to 1945, the Japanese army produced five types of poison gas on Okunoshima Island. The island was so secret that area residents were told to keep away; it was removed from area maps. Today ruins of the old forts and chemical factories can be found all across the island. Chris McGrath, Getty
