What Is a Katashiro? Japan's Purification Custom of Entrusting Defilement to a Substitute

Perhaps you have received a human-shaped piece of paper at a Nagoshi-no-harae or a year-end Great Purification. That paper — the one you write your name on and rub over your body before offering it to the shrine — is called a katashiro. Here we explain what a katashiro is, its history and use in the Great Purification, and Japan's purification culture of entrusting misfortune to a substitute.

What a katashiro is — a stand-in

A katashiro is an object set up as a substitute for a person or thing; the word itself means putting a "shape" (kata) in another's "place" (shiro). The best-known form is paper cut into a human shape, or a small doll — a hitogata. The characters for "doll" can themselves be read hitogata.

Onto this katashiro you move your own defilement and misfortune, and the impurity that has quietly built up day by day. In place of the real you, the substitute takes on that misfortune. Here lies an ancient idea: letting something else shoulder the harm for you.

Katashiro and the "yorishiro"

Seen more broadly, a katashiro is said to be a kind of yorishiro — an object a spirit alights upon. A yorishiro is a target that a divine spirit can settle into: a sacred tree, a rock, a sakaki branch.

A katashiro is a special yorishiro, one shaped as a stand-in for a person or thing. It is given human form so a spirit can readily alight, and onto it you entrust your defilement. Both ideas overlap in the katashiro — the yorishiro's "letting a spirit dwell," and substitution's "letting it shoulder the harm." The thinking behind yorishiro and purification is also covered in what oharai means.

A history reaching back to clay figurines

The culture of entrusting one's feelings to a human-shaped object is said to be extremely old. Clay figurines (dogu) of the Jomon period, human-faced earthenware of the Yayoi period, and human haniwa of the Kofun period — human forms appear in every era and are thought to have carried the character of a vessel for substitution and prayer.

In the written record, too, descriptions connected to katashiro-style purification appear in the Kojiki and the Heian-era legal code Engishiki, and plant materials are said to have been used so the object could be floated on water. The practice of entrusting defilement to a human shape and floating it away has a history of at least a thousand years.

Use in the Great Purification

At many shrines, a Great Purification is held at the year's midpoint in late June (Nagoshi-no-harae) and again at year's end. What is handed out then is the human-shaped paper katashiro. You write your name and age on it, and rub it over the ailing parts of your body or breathe on it to move your defilement onto the paper.

The katashiro that has received your defilement is offered to the shrine and purified — floated on a river or burned. Handing the heavy thing gathered inside you to a substitute and letting it go — the Great Purification is a seasonal rite for returning body and mind to a clean state.

Nademono, nagashi-bina, and how they differ from the straw doll

The same idea appears across many folk customs. Nademono is rubbed over the body to transfer defilement; nagashi-bina entrusts bad luck to a doll and floats it down a river. The hina dolls of the Doll Festival themselves are said to be a trace of the katashiro. Each is rooted in the notion of moving misfortune onto a paper or doll "substitute" and cleansing it in water.

Here it helps to untangle a common confusion. The straw doll of the ushi-no-koku-mairi is also a "human-shaped doll," but its purpose is the opposite of a katashiro's. Where a katashiro is a tool of "purification" — having your own defilement taken on and cleansed — the straw doll has been told of as a tool of "cursing," aiming ill will at another. Even the same doll becomes an entirely different folk custom depending on whether it is aimed at "cleansing oneself" or "attacking another."

Writing and entrusting, as a katashiro for today

Moving defilement and misfortune onto a substitute and letting it go — this wisdom of the katashiro reaches us today in a changed form. Rather than carrying resentment and anxiety just as they are, you can move them, for a while, into another container.

Noroi Nikki is like a katashiro for the present day. You write out swallowed feelings as words of a "curse," cut them away from yourself, and entrust them to the page (the screen). By relocating them to a place no one can see, you gain a little distance from what was swirling inside. The act of writing and entrusting — without hurting anyone — sits on the quiet continuum of a purification carried on since long ago.
