On recent maps of Yakushima, Ishizuka has all but vanished. You have to stumble on an old, time-worn plan to see the name surface again, clinging above the Anbo-gawa valley somewhere around 800 meters of altitude. A former logging hamlet, lost in the mountainous heart of the island, once linked to the port of Anbo by a tiny railway that wound its way between the cedars. For much of the twentieth century, Ishizuka was one of the nerve centers of the yakusugi trade, those thousand-year-old cedars that made carpenters dream and early conservationists wince. Then, in just a few years, the chainsaws fell silent, the residents left, the houses were taken down, and the forest drew a curtain of moss over the whole scene.
The road to a village that no longer exists
I love forgotten corners, the paths that never make it into the brochures, those lines of metal that creak a little too much. I had spotted Ishizuka long ago on an old map of Yakushima, and I had promised myself I would go one day. On paper it sounds like a good idea: you follow the famous forest railway up the valley, soak up the jungle atmosphere and the wooden bridges, and instead of heading for the classic spots, you branch off onto the abandoned line that keeps going toward the vanished village.
On the morning I set out, there is hardly anyone around. A few trekkers on the first third of the route, the ones dreaming of Jomon-sugi and cedar photos for Instagram. Then, all of a sudden, no one. From the junction toward Ishizuka, the line changes its tone.
The comfortable stroll along the maintained rails turns into a crossing of forgotten scenery. The sleepers begin to lean, some sections of track barely hold above the drop, fallen trees block the way, and the vegetation switches into full invasion mode. You move slowly, threading through, testing every step. That was exactly what drew me in: this old line caught in the jungle, these bridges set a little too high above the ravines, this sense of walking on infrastructure that no longer quite belongs to humans.
You hear water running somewhere below, the cries of monkeys echoing in the distance, and now and then a crack of wood that could just as easily come from a branch as from a tired sleeper. The mountain is not trying to scare you, but it gently reminds you that this path was never meant for solitary walkers chasing a rusted kind of beauty.
When the forest had its own little modern town
What makes Ishizuka so fascinating is the contrast between what you see today and what we know of its past life. In the early 1920s, the forestry administration decided to set up a logging base here, right in the heart of the mountain. The hamlet served as a forward camp to cut the cedars, store the logs and organize their descent to the coast. Two years later, a second village, Kosugidani, took root a little lower down, on the other bank of the valley. Two pockets of human life in an ocean of forest.
To move the timber out, they built a narrow railway that followed the Anbo river and linked the camps to the port of Anbo on the coast. On these little lines, tiny wagons hauled the massive trunks toward the sea, while in the other direction came rice, tools, provisions and news from the outside world. At its peak, around 1960, the Ishizuka–Kosugidani complex was home to several hundred people. There were families, children, a school for the kids of both villages, mountain festivals, and a rhythm of life set by the forest more than by the offices of Tokyo.
The day the forest reclaimed the worksite
From the late 1960s, the story flips. The great cedars grew scarce around the camps after decades of intensive cutting, and logging began to lose its appeal. At the same time, the idea of protecting the ancient forests was gaining ground in Japan. On Yakushima, the yakusugi slowly shifted from a resource to a natural heritage worth saving. The worksites closed one after another.
For Ishizuka, what followed was quick. The village closed at the end of the 1960s, Kosugidani soon after. Families packed up their belongings, took their houses apart plank by plank, and carried the materials down on the same rails they had used for years to move the timber. They took everything that could still be useful and left behind everything that had already lost the battle against rust. All that remains are stone foundations, a few low walls, forgotten pieces of metal, and the rails, still there, more stubborn than the rest.
Walking through an erased village
When you finally reach the site of Ishizuka, don’t expect to find ghost houses frozen in time. This is not that kind of ruin. The village was methodically taken apart before it was abandoned. What remains is far more discreet: a line of stones, a mossy low wall, a platform half hidden under the leaves, fragments of tools, scraps of metal eaten by rust. Everything is half swallowed, half visible.
The old railway and its illusions of comfort
On the opposite side from the abandoned branch toward Ishizuka, the main line has become an almost welcoming trail, heavily used by those setting off for Yakushima’s mythical cedars. On these first few kilometers, everything feels relatively reassuring: the rail is in place, the sleepers hold firm, the bridges have been reinforced. You pass groups, walking poles, guides, sometimes even little maintenance shuttles.
Is it worth going all the way to Ishizuka?
Ishizuka is not a place you “tick off” on a Yakushima itinerary. It looks nothing like the marked trails toward Jomon-sugi, nor the easy-access spots. It is a demanding walk, one that takes time, caution, a good tolerance for rickety rails and real self-reliance.
But for those who love the places where modern Japan and forgotten Japan no longer quite overlap, for those who like to feel a buried past rising back up beneath their feet, Ishizuka has something unique. You walk at once through a forest gone wild again and through the backstage of a small industrial epic.
It is neither a video-game set nor an open-air museum.
It is an inhabited emptiness, a place that chose to slip off the map, yet keeps living on in the twisted rails, the mossy walls and the few stone steps that still hold out under the moss.
