The voice outside the sealed room
Hachishaku-sama
An impossibly tall woman appears beyond a garden hedge. Once she chooses someone, height is only the first sign that she is near.
By the Yokai Signal editors · Published · Updated
Every legend leaves two records: the story people repeat, and the path it took to reach them.
01 / THE STORY
A rural visit becomes a containment ritual
In the standard retelling, the narrator is a high-school student who rides a motorbike to the farmhouse of their grandparents during spring break. While resting on the veranda, they hear an odd voice and see a hat gliding along above a hedge that is itself about two meters tall. Through a gap they glimpse a woman in a pale one-piece dress. She is far taller than any hedge should allow.
The grandparents’ mood changes at once. They recognise the figure, name her as Hachishaku-sama, and explain that she has been sealed inside the district by Jizo statues. She is said to favour the young, and once she fixes on someone, that person dies within days. The grandfather fetches an elderly woman, referred to only as K, who hands the narrator a paper charm.
That night the narrator is shut into a room with newspaper taped over the windows and salt heaped in the four corners, with instructions not to leave until morning. Around one o’clock a voice that sounds like the grandfather calls from outside. The narrator nearly answers, then stops. Later something taps on the glass and the low po-po-po sound returns. At dawn the narrator is seated in the middle of a van full of relatives and driven out of the area, still afraid the sound will follow.
Summaries add that the seal on her was broken when someone knocked over a statue, so nobody knows where she is now. That detail is part of the retelling, not a historical claim.
The monster is frightening; the adults’ immediate knowledge of its rules is worse.
02 / THE TRACE
A remarkably traceable beginning
Unusually for a legend, Hachishaku-sama has a birth certificate. Urban-legend researcher Itsuki Asari, writing for web Mu in 2024, dates the first appearance to August 26, 2008, on the occult board of 2channel, now called 5channel. A separate reconstruction of the thread reports that the story was posted by a single user in nine instalments within about ten minutes, as posts 908 to 916 of the 196th thread in the series titled “Let’s collect stories too scary to joke about” That post count and timing come from one secondary reconstruction, so treat them as reported rather than certain.
The series is known as Sharekowa, short for the Japanese title, and it began on August 2, 2000. Folklorist Kosuke Oshimi, who counted thread numbers in a 2022 paper, notes that the series had reached its 364th thread by September 2021. In that paper he places four well-known stories at specific points in the run: Kunekune in thread 31 (2003), Kotoribako in thread 99 (2005), Yamanoke in thread 157 (2007) and Hachishaku-sama in thread 196 (2008).
The opening post of the very first thread explicitly said that stories did not have to be true, because the point was to gather something frightening. That makes the ambiguity honest: the thread proves the text existed on that date and says nothing reliable about whether any family, hedge or district lay behind it.
Eight shaku is roughly 2.4 meters. The English label “eight-foot-tall” is an approximation, not a literal conversion.
03 / VARIATIONS
A figure that keeps changing clothes
The post itself is more specific than the monster that later grew from it. Retellings and fan art differ on her age and dress: some give her mourning clothes and a young face, others a formal kimono and an old woman’s. The reconstruction of the thread lists three traits that survive every change: she is unnaturally tall, she wears something on her head, and she makes an uncanny laugh.
Even the sound is unstable. The grandmother in the story says Hachishaku-sama laughs in a man-like way that is written bo-bo-bo, while the narrator hears po-po-po. The narrator also says it sounds like a person making noise rather than a machine, and cannot say whether it is closer to a b or a p. Those details are easy to lose when the story is shortened to a single catchphrase.
The biggest later change is tonal. In July 2021 Asari recorded a new Hachishaku-sama boom, mostly on Twitter, in which she was drawn beside a young boy as a protective or affectionate figure instead of a predator. The article notes this reading had been present on the internet for years and that earlier booms had also happened.
04 / THE WORDS
Reading the name and the sound
八尺 (hasshaku) means eight shaku. The shaku is a traditional Japanese unit of length, and eight of them come to about 2.4 meters, as both the web Mu article and the thread reconstruction note. 様 (sama) is a respectful suffix. Attaching it to a monster is common in Japanese folklore and can be read as a way of naming something carefully so as not to offend it, though that is interpretation rather than something the post says.
ぽぽぽ (po-po-po) is onomatopoeia for the sound that announces her. It has no stated meaning inside the story and the reconstruction points out that the post never explains why the sound is a p-sound. 魅入られる (mi-irareru), the phrase used for being chosen, means to be taken hold of through attraction or gaze, which is why the story pairs it with a death sentence that arrives after a delay rather than a chase.
盛り塩 (mori-jio) is a small cone of salt placed at a threshold or corner for purification, here set at all four corners of the room. 地蔵 (Jizo) is a Buddhist guardian figure, often a stone statue at a roadside or boundary, and in this tale it is the thing that keeps her contained. 洒落怖 (sharekowa) is the community name for the thread series that carried the story.
05 / CONTEXT
A template that looks like tradition
Oshimi describes a recurring Sharekowa pattern that he says is often called a template: a protagonist meets a local being in the countryside and is saved by a rescuer such as a spirit medium or a temple priest. Hachishaku-sama fits it closely, with the elderly woman K as the helper. The folklorist Ryuhei Ito, quoted in the same paper, argues that online stories like this often pose as inherited tradition by borrowing the look of popular folklore.
The format also shaped the writing. According to the thread’s unwritten norms, a long story should be posted in one run from beginning to end. That plausibly helps explain the sealed, uninterrupted feeling of the original text, since readers met the whole ordeal without a pause.
2channel organised its boards into threads, and Oshimi explains that a popular thread was continued as a numbered series once it hit the posting limit. That structure let a community of readers keep one theme alive for more than twenty years and made every post easy to date afterwards.
06 / PRECEDENTS
Older images it resembles, but does not quote
In his web Mu article Asari lists older Japanese material with similar elements, offered as parallels and not as proof of a source. Folklorist Kunio Yanagita’s book Yama no Jinsei is cited for reports of a woman’s body about eight shaku tall and of mountain women and men of similar height. An early-modern collection of tales, Rōō Chawa, is cited for a mountain witch of seven or eight shaku. The medieval Tsurugi no Maki section of the Tale of the Heike is cited for the story of Watanabe no Tsuna and a demon, in which a figure posing as a relative arrives during a period of seclusion.
The comparison with Tsuna is striking because both stories turn on a sealed space and a trusted voice at the door. But resemblance is not lineage. The thread reconstruction treats Hachishaku-sama as a modern creation from 2008 rather than an old rural belief, and nothing in the post shows that its author had read those books.
07 / AFTERLIFE
From one long post to a global character
Reposts, summaries, illustrations, videos and translated creepypasta turned a specific narrative into a reusable monster. Later creators borrowed the tall silhouette and the call while discarding the family, the room and the escape that gave the original its structure. Academic attention followed too: Ito’s 2016 book on netlore includes a discussion of how Hachishaku-sama’s body is represented online, as Oshimi’s bibliography records.
The character is now familiar enough to be parodied. An indie horror-comedy for PC slated for 2026, Hyakushaku-sama by the developer Neru Neko, is described by the games site Automaton as a short game in which a student visiting grandparents is chased by a giant version about twelve times taller. That game depends on readers already knowing the original proportions.
08 / WHY IT WORKS
Rules make an invented threat feel inherited
The story surrounds its figure with procedures: paper over the windows, salt in the corners, a charm, a deadline, and adults who know exactly what failure means. Those rules imply a history the narrator never sees. This is interpretation, but it explains why readers who never see her face still feel they have learned a system.
The call also travels across media. Repeated syllables are recognisable in text, voice acting, video and games, which allows the character to stay identifiable even when artists change her face or clothing. And the most unsettling beat is not the monster at all but the familiar voice that asks to be let in.

10 / QUESTIONS
Common questions
Is Hachishaku-sama a real Japanese legend or an internet creation?
Both framings are partly true, but the documented evidence points to the internet. The earliest known text is a message-board post dated August 26, 2008. Older books describe unusually tall mountain beings, yet nothing shows they were the source of this particular woman, her ritual rules or her po-po-po sound.
How tall is Hachishaku-sama, and what does the name mean?
Hachishaku means eight shaku, a traditional unit of length, which comes to about 2.4 meters, or about seven feet ten inches. The suffix sama is a respectful title. Together the name reads roughly as Lady Eight-Shaku. Different retellings add different ages and clothes, but height is the constant trait.
What does the po-po-po sound mean?
It is an onomatopoeic call in the story, written ぽぽぽ in Japanese. The post never explains why she makes it. In the telling, the grandmother adds that her laugh is man-like and sounds more like bo-bo-bo. Readers usually treat it as the warning that she is close.
Is it safe to read the story or look at pictures of her?
Yes. There is no documented curse attached to reading it; that idea belongs to horror culture in general. The post is a piece of fiction or claimed experience written for a scary-story thread. If a very graphic image bothers you, simply choose another of the many illustrated versions.
