This is a story I heard from an acquaintance. I thought about going to verify it myself — but the place felt too heavy for that. Too heavy by far.

You may know of the Tōshō-ji ruins in Kamakura. It is said to be where the Hōjō clan met their end. In the third year of Genkō, the year the shogunate fell, Hōjō Takatoki and some eight hundred of his kin and retainers took their own lives, one after another, in the grottos carved into that cliff.

Deep within that site, there is a place known as the Seppuku Grotto.

You can still visit, apparently. During the day.

Now, this acquaintance of mine was a man who kept a camera as a hobby. He was in his early thirties — steadier nerves than most. Near the end of summer, after dark, he went there alone. Not as a dare, he said. He simply wanted to photograph the place at night. That was all.

From the bridge at Tōshō-ji, you follow the path up into the hills, and gradually the lights of the houses fall away behind you. Almost no street lamps. The stone path underfoot had a strange, slick feeling to it — not wet, just slick — and though it was the tail end of August, the air was oddly cold. The air itself was different, he said.

A grotto, in Kamakura, means a horizontal cavity cut into a cliff face — a space hollowed out of rock. Several of these openings gaped in the darkness, mouths hanging open in the black. He said that when he shone his torch into them, the light simply failed to reach the back. Not because the distance was too great — it shouldn't have been — but as though the light dissolved somewhere along the way, swallowed before it could arrive.

He stood there for a while and took his photographs.

It was quiet, he said. No insects. Kamakura summer nights are loud with them everywhere else, apparently, but there — no sound at all.

Then, as he was shooting, he noticed a smell.

Not blood, exactly. Something older. Iron, perhaps, and damp earth, and something else he couldn't name — all of it folded together, drifting quietly into the back of his nose.

He felt ill. He turned to leave.

And then, for no particular reason, he glanced back toward the deepest opening in the cliff.

There was someone sitting inside.

Sitting in seiza — formal, kneeling, back straight, facing away from him. Shoulders present. Head present. Perfectly, completely still.

He said that for a long moment he could not determine whether it was human. Not fear, exactly — he simply could not tell. Living or not living. Even with the torchlight on it, the outline refused to resolve. And yet there was no question: someone was there.

He ran.

When he looked through his photographs afterward, every image opened normally — except for the one he had taken of that particular grotto. The file was corrupted. Only that one. All the others were fine.

Whether it had been damaged, or deleted, or whether anything had been captured at all — he has no way of knowing.

He hasn't gone back to Kamakura after dark since.

But there is one thing that stays with him.

To see something sitting in seiza inside a grotto, with its back to you — that means it has been sitting there, facing the depths of that hollow, all along.

If it has been there for nearly seven hundred years.

What is it waiting for? That question, he says, is the part he cannot put down.
