A group of hikers stumbling onto an abandoned tunnel in the late 1940s is how local legend says this Saitama Prefecture site first came to public attention — and how it started accumulating a reputation that’s outlasted most other tunnel stories from the same era.

What’s Unresolved About This Legend, Even Locally

According to the account, the hikers found strange writing on the tunnel’s walls and a lingering sense of dread they couldn’t explain — later connecting the tunnel to a fatal train accident reportedly occurring there a few years earlier. Since then, the most commonly reported figure is a woman dressed in white, seen near the entrance. Some tellers identify her as a girl who died in the accident; others insist she’s an unrelated spirit entirely, with no consensus reached despite decades of retelling.

Beyond the woman in white, visitors describe moving shadows, unexplained noises, chills, and flickering lights in the distance. The strangest addition to the legend involves claims of ritual activity inside the tunnel — chanting, burning incense, offerings — attributed by some to an informal group using the site for unspecified ceremonies, though the details here are notably vaguer than the rest of the story.

We could not verify the train accident, the wall writing, or the ritual claims against any documented source. The ritual detail in particular reads as the kind of addition that tends to accumulate around abandoned sites over time: once a location has an established reputation for the uncanny, later visitors sometimes interpret ordinary trespassing or vandalism as evidence of something more organized, without that necessarily reflecting what’s actually happening there.

What’s genuinely notable about Motokawa Matarata Tunnel is how much of its own story remains unresolved even among the people who tell it — who the woman in white actually is, whether the rituals are real, whether the tunnel’s dread is supernatural or simply the product of an abandoned, unlit space. Most legends settle into a fixed version over time; this one hasn’t, at least not according to the accounts that circulate locally. Part of that may trace back to its discovery-based origin: unlike legends tracing to a specific historical tragedy, a hikers-stumbled-onto-it opening leaves more room for ambiguity, since no one set out looking for a haunting in the first place.

Can You Visit?

The tunnel remains an abandoned structure in Saitama Prefecture. Given its age and lack of maintenance, any visit should prioritize structural safety over curiosity about the reported hauntings or rituals.

Did a train accident really happen at this tunnel?

We could not verify the train accident, the wall writing, or the identity of the woman in white against any documented source.

Is the reported ritual activity confirmed?

No — the chanting and offerings some describe are notably vaguer than the rest of the legend and unverified by any source we located.
