Just off the coast of Takehara, there’s a small island in the Seto Inland Sea.
The island is called Okunoshima.
The 15-minute ferry ride from Tadanoumi Port is a beautiful journey, especially on a sunny day, when the inland Sea is at its beautiful, sparkling, beguiling best, with the islands hazy in the morning sun.
Stepping off the ferry, the island feels peaceful, and deeply relaxing.
Quiet lanes around the circumference of the island, bordered with vibrant azaleas, the soft sea air, and the lapping of the waves against the shore, never far away. And the breathtaking views out over the Inland Sea. It could be heaven.
But even more than the stunning scenery, what makes Okunoshima truly unusual is that you’re never really alone.
Rabbits appear everywhere.
They gather along the paths, rest in the grass, and wander freely across the island, completely at ease in their surroundings. And completely eager to come running at the merest hint of food.
There’s something strangely calming about watching them go about their lives, unbothered by the humans around them.
And yet, beneath the calm surface, the island of Okunoshima hides a very different past.
During World War II, Okunoshima was a site of poison gas production. With access restricted to military personnel only, for a time, the whole island disappeared from maps, such was the top-secret nature of what was being done there.
After Japan’s defeat in 1945, the toxic materials were buried or removed, and the facilities destroyed or dismantled. Even so, the island was dangerous and largely avoided. Access was extremely limited and not encouraged.
It wasn’t until the 1960s that the island was redeveloped, and became the site of a kyukamura (休暇村), a national holiday resort facility. And now, with the cuteness factor of hordes of rabbits running wild, the island is perhaps the most popular destination in this part of Hiroshima Prefecture.
Some people say the rabbits are descended from those used during the island’s poison gas production period in World War II. However, there’s no strong evidence for this, and more widely accepted is the theory that in the 1970s, a group of schoolchildren released a handful of rabbits onto the island after using them for science experiments. With no natural predators, a mild climate, and plenty of vegetation, the rabbit population grew rapidly.
The island is commonly known by the epithet ‘Rabbit Island’ these days, but nevertheless, parts of its darker history, the history of its role in World War II, still remain visible. Quiet ruins, scattered across the island, almost hidden among the trees. If you look closely, the island hasn’t forgotten its past.
Close to the port, the power plant ruins are one of the more recognizable structures on the island. They are the remains of a concrete-built power station that supplied electricity to the other facilities. These industrial remains, in a quiet natural setting, overgrown and succumbing to vegetation, provide a striking visual contrast.
And, now mostly overgrown, nothing more than crumbling concrete walls and the outlines of buildings, there are the poison gas production facilities, and various other laboratory and storage buildings. It is sobering to think that here, in such a beautiful location, toxic gases like mustard gas were produced.
Also, around the island from the port, are the gun batteries, defensive positions built to protect the island. The emplacements, facing out to sea, are a reminder that the island was a military site, not just an industrial one.
Still, today the island is tranquil, serene, idyllic. The island now is for leisure, and wartime workers have been replaced by holidaymakers and day-trippers. You can play sport, you can hire bicycles, there’s a restaurant, there’s even a public bath. But for me, one of the best things is just to sit on the sea wall and gaze out at the Inland Sea, the islands, the little fishing boats, the beautiful pellucid waves. It really is heaven.
But in the end, with reminders all around, the island’s past cannot be forgotten, nor should it be. The remnants of the island’s dark wartime history only serve to emphasise its current calm peacefulness. And actually, nothing symbolises the contrast between past and present better than the gorgeous cherry blossoms in spring. They’re so wonderful, it’s almost as if they’re trying to atone for what happened here in the first part of the last century.
So, rabbits and ruins: Okunoshima is a place where two very different worlds exist side by side. A peaceful island filled with enjoyment and life, and the memory of something much darker.
Strolling around the island, with the sound of the sea, the calm beauty of the Inland Sea, the multitude of rabbits, the softness of the light on one hand, and the quiet weight of history on the other, never too far away, you can’t help but feel that contrast.
Okunoshima isn’t just a place to visit.
It’s a place for quiet contemplation.
