Hachishakusama: Japan’s Eight-Shaku Woman and Her Folklore Origins

The Story in Brief

Hachishakusama is an impossibly tall woman whose strange ‘po… po… po…’ announces that she is nearby. In the story that made her famous, she chooses a young visitor to a rural community, imitates the voice of someone he trusts and follows him as his family tries to get him away.

It sounds like a local legend passed down for generations. The grandparents recognise her. The neighbours know the rules. Religious statues mark the limits of her territory. Yet the character’s documented history is generally traced to an anonymous Japanese forum story posted in 2008.

That does not mean every idea in the story was new. Japanese folklore already contained enormous women, dangerous mountain figures and supernatural encounters far from ordinary settlements.

The interesting question is therefore not simply whether Hachishakusama is ‘real folklore’ or an internet invention. It is how a modern horror story uses familiar motifs, and how retelling gives a new character a history of her own.

What Does Hachishakusama Mean?

The name 八尺様 is usually rendered as Hachishakusama or Hachishaku-sama. Hachi means eight, shaku is a traditional unit of length, and sama is an honorific. ‘Eight-Shaku Woman’ is a convenient English description, rather than a literal translation of every part of the name.

Using the standard modern shaku of roughly 30.3 centimetres, eight shaku comes to about 2.42 metres, or just under eight feet. Measurements called shaku have varied historically, so ‘eight-foot woman’ works best as an approximate English label.

Her height makes the first encounter unsettling before anything openly threatening happens. A hat appears above a hedge. Only when the figure reaches a gap does the narrator see that it belongs to a woman whose proportions do not fit the setting.

The 2008 Story: A Voice Outside the Door

The account is commonly traced to 26 August 2008 on the Occult board of 2channel. Its anonymous narrator says the events happened more than ten years earlier, while he was still at school. That earlier date belongs to the story’s claim; it is not independently documented evidence of an older tradition.

During a visit to his grandparents, the teenager sees a tall woman in a pale dress and hears an odd repeating sound. His grandparents become frightened when he describes the encounter. They tell him that Hachishakusama has taken an interest in him.

An elderly woman helps prepare a protected room. The boy must remain inside until morning and ignore anyone who calls for him. During the night, a voice sounding like his grandfather tells him that it is safe to come out. Remembering the warning, he refuses.

The following morning, relatives surround him inside a van as a convoy takes him out of the district. The woman appears alongside them. The tapping and the voice return, then stop after the vehicles cross the boundary.

In the account, four Jizō statues contain her within the area. The narrator never visits again. Years later, he hears that one of the statues has broken: the one on the road towards his family’s home.

An Old Legend Inside a Modern Story

The story gives Hachishakusama a past before the reader ever meets her. Older relatives possess knowledge that the narrator lacks. The villages have supposedly negotiated boundaries and learned to live with the danger.

Those details create the feeling of inherited local knowledge. They also make the escape depend on listening to people who understand the place, rather than discovering a monster’s weakness through force.

But the history described inside a narrative and the documented history of that narrative are different things. A character can be said to have haunted a village for generations without there being surviving evidence that villagers actually told the story before its publication.

The protective room, salt, charms and statues should be read as elements of this particular account. They are not a verified set of real-world instructions for surviving a supernatural encounter.

Japan Already Had Enormous Mountain Women

Kunio Yanagita’s Yama no Jinsei, or Life in the Mountains, records an account from Kumano involving the body of a woman said to be around eight shaku tall. Her long hair, large eyes and unusually wide mouth place her well outside an ordinary human description.

Yanagita also discusses mountain women, often called yamauba or yamamba, whose appearance differs between traditions. Remote settings and accounts involving people being carried away offer further points of comparison with modern horror.

These examples matter because extraordinary female height was already present in Japanese folklore. The anonymous forum writer did not need to be the first person to imagine a giant woman.

However, resemblance does not demonstrate descent. There is no established evidence that the author read Yanagita, borrowed a particular mountain-woman story or intended Hachishakusama to be a yamauba.

Taka-onna, the ‘Tall Woman’ known from Edo-period yōkai imagery, offers another visual comparison. A shared elongated appearance is a reason to compare figures, not a reason to treat them as the same being.

The Comparison with Slender Man

Slender Man appeared on the Something Awful forums in June 2009, after Hachishakusama’s recorded debut. Eric Knudsen, posting as Victor Surge, introduced the tall, faceless figure through manipulated photographs and accompanying captions.

The resemblance is broad: an unnaturally tall humanoid, young people in danger and a story circulating through online communities. Their appearances, settings and subsequent development are different.

There is no established evidence that either character was based on the other. Chronology also rules out the 2008 Hachishakusama story borrowing from Slender Man’s 2009 debut.

Andrew Peck’s research on Slender Man is useful here because it examines how a figure created online can become material for shared legend-making. A traceable modern beginning does not prevent people from developing stories, images and expectations around a character.

When an Internet Monster Gains a History

The term creepypasta tells us something about how a horror story circulates online. It does not settle everything about what happens when readers translate it, adapt it and tell it to someone else.

Hachishakusama’s identity is recognisable even when a retelling changes details. Her exceptional height and distinctive call let an audience connect a new version with the figure they already know.

That continuing process is part of the documentary’s argument. A writer gave the woman an apparently ancient history inside a story. Readers then began building a documented history of retellings outside it.

We can discuss her as a modern supernatural legend without claiming that an ancient creature called Hachishakusama has been rediscovered. The older comparisons make her more interesting, but they do not erase the difference between evidence and possibility.
