The Island Where Rabbits Outnumber Humans by Thousands

Exploring Okunoshima, a tranquil island where rabbits outnumber humans by thousands, reveals a compelling tale of ecological transformation, wartime history, and modern wildlife conservation off Japan’s coast.

Nestled in the Inland Sea of Japan near Hiroshima Prefecture, this tiny landmass draws international eco-tourists fascinated by its thriving population of friendly, free-roaming feral rabbits.

What is the history behind Okunoshima and its rabbit population?

Before transforming into a celebrated animal sanctuary, Okunoshima carried a dark secret, serving as a top-secret chemical weapons production site for the Imperial Japanese Army.

Between 1929 and 1945, secret facilities manufactured poison gas on the secluded island, leading authorities to erase the territory from official military maps to preserve absolute secrecy.

Local lore often attributes the current rabbit population to test animals released after World War II, though historical records indicate those original subjects were humanely euthanized during Allied deactivation.

Visiting this unique island where rabbits outnumber humans today allows travelers to witness how nature reclaimed land previously dedicated to industrial military operations in the early twentieth century.

How did rabbits colonize the island to create a unique sanctuary?

Modern rabbit colonies actually trace their ancestry back to a small group of domestic rabbits introduced by school children in 1971, expanding rapidly in predator-free isolation.

Without native carnivores like foxes, cats, or dogs, the lagomorphs multiplied across the island’s lush forested hillsides, coastal paths, and abandoned military ruins over subsequent decades.

Strict environmental regulations enforced by local municipal authorities forbid visitors from bringing outside pets, ensuring the delicate ecosystem remains safe for the thriving, uninhibited feral community.

This protective management strategy allows thousands of fluffy inhabitants to approach human visitors fearlessly, creating a gentle environment found nowhere else on the planet today.

Which rules ensure responsible interaction between visitors and the wildlife?

Maintaining animal welfare requires strict adherence to seasonal feeding protocols established by conservationists to prevent digestive illnesses among the delicate, wild rabbit population.

Tourists must purchase certified rabbit food at mainland ferry terminals, refraining entirely from offering human snacks, processed carbohydrates, or raw cabbage leaves in excess.
