Japan is a country of perpetual surprises, defined by the tension between deep tradition and relentless innovation. Its cities rise in forests of glass and steel that seem borrowed from another century, yet step beyond the urban edge and the countryside preserves its quiet, timeless character — the Japan that has always existed beneath the spectacle.
In barely 150 years, this nation raced through centuries of transformation in a single breathless span, marked by wars, atomic bombings, and natural disasters on an almost unimaginable scale.
It is no accident, then, that Japan has produced some of the darkest legends in the world.
Rooted in a singular cultural and religious sensibility, the Japanese hold a deep belief in yurei — spirits of the dead, not unlike Western ghosts, who linger in the world of the living.
Alongside them are the yokai — demons, essentially, since they never inhabited a human body and carry no grief, only mischief and malice.
And all of them, it seems, have chosen a favorite haunt in Kyoto: the Kiyotaki Tunnel, shrouded in terror.
A Cursed Place From the Very Beginning
The Kiyotaki Tunnel was built in 1927 to cut through a mountainous stretch in the Ukyo district on the outskirts of Kyoto.
Such structures are common across Japan, a country whose complex, rugged topography demands engineering solutions to tame the landscape. Roads have to be carved through difficult terrain, and tunnels are a common sight. What was also routine, in the early 20th century, was the use of slave labor to build them.
At the time, Japan was going through a turbulent era, locked in a widening armed conflict with China. It was standard practice to put prisoners of war to work on the brutal, dangerous task of building tunnels.
Landslides were frequent, and with virtually no safety measures in place, they were almost always fatal. The prevailing logic of the era was cold and simple: these workers were expendable, replaceable without a second thought.
Many of those workers are said to have been buried alive during the construction of the Kiyotaki Tunnel — a history that would be enough on its own to cast a long shadow over the place. But there is more.
The tunnel’s official length is 1,457 feet (444 meters). To most Western eyes, that number means nothing. But in East Asian culture, it carries a symbolic weight that is anything but neutral.
In Japan and China alike, the number four is associated with death, feared the way Westerners fear the number 13, and is avoided in hospitals, hotels, and everyday life. That the length of this sinister tunnel contains that digit three times over seems far from coincidental.
And then there is this: many visitors insist that the tunnel’s length shifts depending on when you enter. For some, it stretches impossibly long. For others, it contracts. Some drivers say they passed through the Kiyotaki Tunnel and arrived hours later than expected, without taking any detour, and with no explanation. As if time itself stops obeying the laws of physics inside those walls.
Ghosts and Omens at Kiyotaki
Every story about this tunnel shares a common thread: the curse that seems to cling to it. Whether it stems from the deaths of those laborers or from the tunnel’s link to the number associated with death, hundreds of witnesses claim to have experienced paranormal encounters while passing through the Kiyotaki Tunnel.
The most common account involves sensing ghostly presences around the car as it moves through the tunnel. A traffic mirror is mounted on one of the tunnel’s interior walls to improve visibility. Many drivers have looked into it and seen something that shouldn’t have been there — a grim figure reflected in the glass. Those who have seen it say it is an omen — a sign that the viewer’s own death is near.
Other accounts go further. Some claim that spirits — or perhaps the more mischievous yokai — slip into passing vehicles and cause accidents inside the tunnel.
There have, in fact, been quite a few accidents here over the century the tunnel has been in use, and a significant number of deaths — but statistically no more than you’d expect from any tunnel of similar age and size.
The curse, it seems, reveals itself less in the accidents than in strange encounters with otherworldly beings: ghostly apparitions, blinding lights in the dead of night, and inexplicable distortions of time — all of which keep the legend of Kiyotaki alive as one of Japan’s most enduring.
Enduring enough, in fact, to have inspired Dandadan, one of the most popular manga series in Japan in recent years. In its anime adaptation, the tunnel the protagonists travel through to encounter a peculiar yokai bears unmistakable similarities to the Kiyotaki Tunnel, famous throughout Japan.
