The bunny-ear designs on the window apart, there may be little to point that the ferry has arrived on an island teeming with rabbits. Then, moments after the passengers disembark, there may be exercise within the undergrowth. A single rabbit scampers out, wholly untroubled by its two-legged guests. After which one other.
A brief stroll alongside the coast takes guests deep into rabbit territory on Okunoshima, one in all 3,000 islands in Japan’s Seto Inland Sea. Half a dozen of the animals push back one other because it makes an attempt to affix them in a communal meal of Chinese language cabbage. The scene unfolds in entrance of smiling, camera-toting vacationers barely capable of imagine their proximity to Okunoshima’s fabled – however troubled – furry residents.
The 2 gray rabbits that greeted the ferry from the mainland return to bushes stripped of their leaves. Shallow bowls of water left by volunteers dot the island in locations the place its estimated 400-500 rabbits are inclined to congregate in expectation of pellets of meals left by guests within the absence of their pure eating regimen of fallen leaves, bark, roots and grass.
For all its pure magnificence and recognition as a vacationer vacation spot, Okunoshima – uninhabited besides for employees working on the solitary resort and its company – faces an unsure future, and so do its four-legged inhabitants.
From 1929 till the tip of the second world struggle, the island hosted toxic gasoline analysis and manufacturing amenities run by the Japanese imperial military. The operation was so secret that Okunoshima was not included in contemporaneous maps of Japan.
Staff in rubber uniforms, gloves, lengthy boots and gasoline masks manufactured mustard gasoline, and smaller portions of teargas and cyanide.
The manufacture of weapons of chemical warfare – which was not uncovered till the Nineteen Eighties – additionally marked the start of the island’s connection to rabbits. About 200 had been utilized in experiments to check the efficacy of gasoline that Japan’s military used through the Sino-Japanese struggle and, later, to arm balloon bombs focusing on the US.

Within the early Nineteen Seventies, a close-by elementary college launched a small variety of rabbits on the deserted island, hoping they might convey it again to life. In 2024, almost 200,000 individuals visited Okunoshima, drawn by its eminently Instagram-friendly shoreline and the promise of coming into a rabbit paradise.
An curiosity in wartime historical past first introduced Koji Yamamoto to Okunoshima 5 years in the past. However it’s the rabbits that hold him coming again. “That is my thirtieth time right here,” the retiree says as he watches gray rabbits gratefully devour the pellets he has put out for them.
“There isn’t a lot pure vegetation, so I believed it will be a good suggestion to return often and feed them, particularly through the winter when there aren’t many vacationers.”
Defeated Japanese forces tried to destroy proof of their wartime actions, together with exterminating their assortment of white lab rabbits.
Specialists haven’t dominated out a genetic hyperlink between the rabbits experimented on in wartime and people who roam Okunoshima immediately. The possibilities are, although, “very low”, says Shingo Kaneko, a professor within the college of symbiotic methods science at Fukushima College, who’s learning the rabbits’ DNA to study extra about their lineage.
“Even when a person rabbit survived [the wartime experiments] it will have been very tough to proceed its lineage. However I can’t say 100% no, and it’s a narrative that individuals wish to imagine might be true.”

Kaneko’s examine of lots of of droppings revealed that the rabbits have various DNA traits, suggesting that animals have been left on the island on a number of events, probably by individuals hoping to offer undesirable pets a brand new residence.
Unable to compete with bigger animals for dwindling crops of pure meals, the rabbits at the moment are fully depending on guests and volunteers for sustenance, in keeping with Kaneko. “They rely upon individuals for meals, and that’s not good. There’s not sufficient pure meals,” he says. “The rabbits look pleased sufficient in social media posts, however they’ve an more and more precarious existence.”
Yamamoto won’t depart his spot till the rabbits have eaten each final morsel. “It’s a must to stick with them till they’ve completed, in any other case different animals come and assist themselves,” he says. The predators – normally wild boar and crows – not solely eat the rabbits’ feed, however have been recognized to assault them.
Final 12 months, their chief tormentor was Ryu Hotta, a 25-year-old who was given a suspended jail sentence after being discovered responsible of abusing a number of rabbits by kicking them or inserting scissor blades of their mouths. Media studies stated the carcasses of 77 rabbits had been found on Okunoshima between November 2024 and January final 12 months, though it was not clear what number of had died on account of abuse.
As concern grows over the way forward for the rabbit inhabitants, some fear that the island’s previous might be forgotten.
“About 85% of people that go to Okunoshima come to see the rabbits and provides this place a miss,” says Kazuhito Takashima, who manages the Poison Fuel Museum, the place reveals embrace uniforms worn by plant staff and images of the disfigurements they suffered after publicity to harmful chemical compounds. “Most Japanese individuals don’t know in regards to the toxic gasoline amenities … we didn’t find out about this type of factor in school.”
