Hey, have you heard about it? The Kotubo Tunnel.

It sits quietly on the border between Kamakura and Zushi — one of those places that people who know, know. Apparently it's even been featured on one of those paranormal TV programs.

But the thing is, what they showed on television and what people actually say when you're there in person — they're not quite the same. What I'm about to tell you didn't come from any TV show. It came straight from someone who was there. Someone who says it happened to them. Whether it's true or not, well — I really can't say.

This person — I'll call them K. Last autumn, just past one in the morning, K was driving alone through that tunnel on the way home. No particular reason to be there, just passing through. K had driven that road plenty of times in daylight and didn't think anything of it.

Inside the tunnel, the headlights swept across the walls, and everything beyond that circle of light was just darkness. The way tunnels are. At first, nothing felt wrong.

But somewhere around the middle — K noticed a smell. Drifting up from somewhere deep in the sinuses. Incense. All the windows were closed, and yet it was unmistakable. Dense, like someone nearby was burning it.

K's foot eased off the accelerator.

And that's when the rearview mirror caught K's eye.

There was someone in the back seat.

A woman in white, head bowed, sitting there. Long hair hanging down, face hidden. But even with her head down — her shoulders were moving. Slowly. Rhythmically. Like she was laughing. Not a sound. No breath, no presence, nothing — only those shoulders, rocking in silence.

K pressed down on the accelerator and drove straight through to the other end. Couldn't stop, K said. It wasn't exactly fear — it was the thought of stopping, of seeing her any closer than that. That was what was unbearable.

Once out of the tunnel, K pulled into a convenience store parking lot and checked the mirror again with trembling hands.

No one was there.

The back seat was empty.

But here's the thing. When K got home that night and went to take off the coat, that's when it became clear. On the shoulder of the coat — four distinct creases, pressed deep into the fabric. The shape of fingers.

Like someone had reached forward from behind and gripped K's shoulder.

There have always been accidents at Kotubo Tunnel, or so people say. And K isn't the only one who's mentioned the woman in white — or the figure that looks like an armored warrior. More than one person has looked at the dark stains on the tunnel walls and said they look like old blood.

No one knows why spirits gather there. A few people have apparently tried to find out, but whenever you ask them about it, they go quiet. They won't say any more than that.

There's just one thing I keep coming back to.

K still hasn't thrown away that coat.

It's been hanging in the closet ever since. I asked why — why not just get rid of it? K was quiet for a moment, and then said:

"If I throw it away… I'm afraid she'll notice."
