The Origins of Okunoshima
Okunoshima, a small island located in the Inland Sea of Japan, is known globally as the 'Rabbit Island.' While visitors flock to see the hundreds of free-roaming European rabbits, the island's history is somber. According to the Okunoshima Visitor Center, the island served as a secret chemical weapons manufacturing site for the Imperial Japanese Army between 1929 and 1945.
The Rabbit Population Myth vs Reality
A common misconception is that the rabbits are descendants of test subjects from the chemical plant. However, researchers from the Ministry of the Environment have clarified that the original lab rabbits were euthanized or released after the war. The current population likely originated from a small group released by local schoolchildren in 1971.
