What are all these rabbits doing front an empty Japanese hotel?
Would you believe the bunnies are escaping an abandoned chemical warfare plant?
The photo was taken in what is now an island park called Okunoshima located in the Inland Sea of Japan in Hiroshima Prefecture (see map below).
However, from 1925 to 1945 the island was a top secret chemical weapon facility (R) that produced over six kilotons of mustard gas and tear gas. Now Okunoshima is an island with a hotel, a six-hole golf course and a camp ground. When the island was developed as a park after World War II, these rabbits were intentionally set loose. Many rabbits were used in the chemical munitions plant to test the effectiveness of the chemical weapons during World War II (Wiki).
