The picture, plainly
The thing that pulls your hair back
A retelling, not a citation. What follows is the story as the most widely circulated popular accounts tell it — folklore encyclopedias, translations, and the versions that have travelled furthest. It is synthesized rather than keyed line by line to the dated primary texts, and popular versions drift from what those texts actually say. The cited, source-by-source record begins further down this page, and where the two disagree, the record wins.
A female figure with a single eye on top of her head, materializing behind you, to tug at the hair at the back of your neck.
Sekien, 1784.
The name is an idiom made flesh
There's a Japanese expression: *ushirogami wo hikareru — "to have one's back hair pulled."*
It means the drag of reluctance. Leaving somewhere while your heart is still there. Walking away from something you haven't finished feeling.
Anyone who has left a house for the last time, or ended something they weren't sure about, knows the physical sensation the idiom describes — a pull, from behind, at the base of the skull.
And Sekien crossed that phrase with *kami*, god.
The god of the pulled-back hair.
Murakami reads it flatly: wordplay — "a supernatural entity representing indecision" — not field folklore.
The single eye is the design masterstroke
And nobody glosses it, so I will.
A thing that lives behind you needs no face. Only a periscope.
She has one eye, and it is on top of her head, because everything she needs to do happens at the back of your neck, where you cannot look, and the eye simply has to clear the top of her skull to see you.
It's a piece of functional anatomy, worked out for a creature whose entire existence is the space directly behind a person.
Saikaku gives it the worst possible use-case
The great Edo novelist invokes the spirit as the thing that causes parents' hesitation when they are considering disowning a child.
Which is the idiom at its most painful, given an agent.
Not a metaphor for a father's reluctance. A presence in the room, with a hand in his hair, while he decides.
The other version is much smaller and quite funny
Other sources make it a harasser of the timid — someone who ruffles your hair, breathes hot air on the back of your neck, and flips your umbrella inside out.
Which is a completely different creature: not the weight of an unmade decision, just a thing that picks on nervous people in the street.
And later texts file it under *okubyō-gami — cowardice spirits.*
Which is, I'd argue, the tradition's least famous and most relatable pantheon. A whole class of small beings whose only function is to make already frightened people more so. There's one that produces the shiver up your spine. There's one that pulls your hair when you can't decide.
Nobody builds shrines to these. Everybody has met them.
The psychology shelf
This tradition does something specific and does it repeatedly.
Take an interior state that already has an idiom attached — and print the idiom's literal image as a being.
Hesitation becomes a hand in your hair.
Sleep paralysis becomes something sitting on your chest, and gets a name, and a counter-rite.
The shiver becomes a small thing that climbs you.
Which means a meaningful slice of Japan's monster catalogue isn't a bestiary at all. It's a phrasebook of internal experience, illustrated.
Run this one with the paralysis-spirit and you get the two-body problem of Japanese fear: the spirit that stops you leaving, and the spirit that stops you deciding.
If you draw it: pure point of view. The reader's own nape, and one strand lifting.

Overview
A female ghost-figure with a single eye atop the head, materializing behind you to tug your back hair — Sekien, Konjaku Hyakki Shūi (1784) [sekien-1784]; [ja-ushirogami]. The name is the idiom made flesh: ushirogami wo hikareru — "to have one's back hair pulled" — Japanese for the drag of reluctance, leaving with your heart still behind you — crossed with kami, god [ja-ushirogami]. Murakami reads it flatly as wordplay, "a supernatural entity representing indecision," not field folklore [ja-ushirogami].
The record
- Saikaku's cameo: the spirit invoked as what causes parents' hesitation "when considering disowning children" [ja-ushirogami] — the idiom's most painful use-case given an agent.
- The trickster face: other sources make it a harasser of the timid — ruffling hair, breathing hot air on the neck, flipping umbrellas [ja-ushirogami].
- The taxonomy: later texts file it among okubyō-gami, cowardice-spirits [ja-ushirogami] — the tradition's least famous and most relatable pantheon.
- The Mizuki layer: Tsuyama (Okayama) accounts with more malevolent encounters [ja-ushirogami] — audit-flagged as usual.
The reading
The psychology shelf's cleanest exhibit. The tradition keeps doing this: take an interior state with an idiom attached, and print the idiom's literal image as a being — hesitation becomes a hand in your hair. The single eye on top of the head is the design masterstroke nobody glosses: a thing that lives behind you needs no face, only a periscope. Run it on the site with kanashibari as the two-body problem of Japanese fear — the spirit that stops you leaving, and the spirit that stops you deciding.
