Kashima-san doesn't knock. She calls, or she shows up in a dream, and she asks you a question you were never taught to answer.
“Do you want legs?”
That's the core of the legend. A woman missing her lower body — sometimes both legs, sometimes cut off at the knee, sometimes just gone — appears to someone who has recently heard her story, and demands a reply. Get it wrong, or hesitate too long, and she takes what she asked about. Get it right, and you're safe, at least until the next time someone whispers her name to you.
What the Question-and-Answer Actually Looks Like
The ritual survives because it has rules, and Japanese schoolchildren have traded slightly different versions of those rules for decades. In most tellings, Kashima Reiko phones you, or appears at the end of your bed, and asks something like “kore o shitteiru ka” (do you know about this) or, more directly, whether you want the body part she's missing. The “correct” answers vary by region and by whoever's retelling it, but they cluster around a few moves:
- Answer instantly. Silence or a pause is treated as a wrong answer by default.
- If she asks for a hand or a leg, say you're already using it — “ima tsukatteimasu,” roughly "I'm using it right now."
- If she asks who told you about her, the safest reply is her own name, sometimes broken into syllables like a chant: ka is from “mask” or “fire,” shi from “death,” ma from “demon.”
- Some versions add a second layer of protection: telling the story to someone else within three days, passing the obligation forward the way a chain letter passes bad luck.
None of this is standardized, which is itself part of why the legend has stayed alive. A story with one fixed script gets memorized and forgotten. A story where everyone's cousin swears the “real” answer is slightly different keeps getting retold, and re-argued, at every school in the country.
Where the Story Seems to Have Started
Pin down an exact birthdate for Kashima-san and you'll find several, none of them fully confirmed. One commonly repeated timeline places the legend's spread in the early-to-mid 1970s, moving south from Hokkaido, while other tellings trace it to the late 1970s in the direct wake of the Kuchisake-onna (slit-mouthed woman) panic that swept Japanese schools starting in 1978-79. Some versions attach her to a specific, uncorroborated backstory: a woman injured after the war, or a suicide at a train station, her legs severed by an oncoming train.
None of these origin stories has a documented source — no newspaper report, no named location that checks out under scrutiny. What can be said with confidence is that Kashima-san belongs to a well-documented wave of Japanese school-yard horror that spread by word of mouth in the 1970s-80s, the same social mechanism that carried Kuchisake-onna and Hanako-san through playgrounds nationwide, and that the specific “who was she really” backstories are folklore layered on top of a rumor, not verified history.
Kashima-san and Teke Teke: Related, But Not the Same Story
Ask five people about Kashima-san and Teke Teke and you'll get five different opinions on whether they're the same figure. Teke Teke — the legless ghost said to drag herself along train platforms and roads, making a dragging or clicking sound as she goes — is often described as sharing an origin with Kashima Reiko, and in a lot of internet-era retellings, Teke Teke's backstory borrows Kashima-san's wholesale: the same postwar injury, the same missing legs, the same railway death.
But the two don't function as the same kind of story. Kashima-san is defined by an interaction — she asks, you answer, you live or you don't. Teke Teke is defined by pursuit and sound — she chases, she drags herself, sometimes she's simply glimpsed and that's the whole encounter. It's entirely possible to tell a Teke Teke story with no question-and-answer ritual at all, and a Kashima-san story with no chase. The overlap in physical description (a woman, legless, connected to trains) is probably what pulled the two into the same orbit over years of retelling, rather than either being a deliberate variant of the other. Whether they were originally one legend that split, or two separate legends that fused because they resembled each other, isn't something the available sources settle — it's genuinely disputed among the people who've tried to trace it.
Where “Kashima Reiko” Came From
The name itself gets treated as part of the puzzle, not just a label. The most common explanation floating around is a syllable-by-syllable reading, where each sound in “Kashima Reiko” is reinterpreted as a small omen: ka linked to “mask” or “fire,” shi to “death,” ma to “demon,” rei to “spirit,” ko to “accident.” Under this reading, chanting the name back to her is less a factual answer than a kind of protective spell, which is why some versions of the ritual have you recite the broken-apart name instead of answering the question directly.
There's no scholarly consensus that this etymology is the “real” one rather than folk wordplay invented after the fact to make the legend feel more designed and less random. It's also worth noting that “Kashima” is a real, fairly common Japanese place name and surname, unconnected to the ghost story in any documented way — so readers researching the name independently shouldn't assume every “Kashima” reference is legend-related.
A Legend With No Fixed Shape
What makes Kashima-san worth taking seriously as folklore, rather than dismissing as a copycat of Kuchisake-onna, is exactly what makes her hard to pin down: no fixed gender, no fixed backstory, no fixed ritual, no fixed relationship to Teke Teke. She's less a single ghost story and more a template — a question you can't refuse, a body missing something, an answer you'd better know before the phone rings.
Frequently Asked Questions
Is Kashima-san the same ghost as Teke Teke?
Not necessarily. They're closely associated and often share a backstory in modern retellings, but they function as different kinds of encounters — Kashima-san through a question-and-answer ritual, Teke Teke through pursuit. Whether they originated as one legend or two that merged is disputed, not settled.
What happens if you answer Kashima-san's question wrong?
In most versions of the story, she takes the body part she asked about — a hand, a leg — from whoever failed to answer correctly or hesitated too long.
Where did the Kashima-san legend start?
No single origin is documented. It's generally placed in the school-yard horror wave of the 1970s-80s, the same period that produced Kuchisake-onna, but the specific “true story” backstories attached to her (a postwar injury, a train station suicide) aren't independently verifiable.
What does the name “Kashima Reiko” mean?
The most repeated explanation reads each syllable as an omen — death, demon, spirit, accident — though this is folk etymology rather than a documented origin for the name.
Kashima-san sits alongside a wider catalog of Japanese school-yard hauntings — the ghost who won't leave the girls' bathroom in Hanako-san, and the dragging figure most often confused with her, Teke Teke.
