The object, plainly
The rope that draws the line
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.
This whole tradition is about boundaries. The sealed pass at the edge of the underworld. The unlucky corner. The birth-hut door. The bridge, the crossroads, the village edge, the hour when the light goes.
And Japan's everyday, physical embodiment of all of it is a rope.
Shimenawa — laid rice-straw or hemp, hung with white paper zigzags called shide.
It marks a ritually pure area. It wards spirits. And it wraps the trees and rocks where a kami is understood to dwell.
You've seen it around an enormous old cedar. Across a shrine's gate. Around a pair of rocks in the sea. On the front door at New Year, in miniature.
One technology, drawn in straw.
It was first hung behind the sun
The origin is the best story in Japanese mythology, and this object is its punchline.
Amaterasu, the sun goddess, shut herself in a cave and the world went dark.
The gods tried everything. What finally worked was Ame-no-Uzume climbing onto an upturned tub and performing a dance so outrageous that the assembled gods roared with laughter — and the sun goddess, unable to bear not knowing what was so funny, opened the door a crack to look.
They pulled her out.
And then the god Futodama stretched a rope across the cave mouth — to stop her going back in.
That's the first shimenawa.
It wasn't hung to keep something out. It was hung behind the sun, as a boundary against the world going dark again.
Every rope since repeats that gesture.
The sizes are absurd
They run from a few centimetres to monstrous.
The great rope at Izumo Taisha — the shrine built as the price of a god's surrender of the land — is 13.5 metres long and 8 metres around.
It hangs over the entrance like a fallen tree. People throw coins up into it and try to make them stick.
And a human being wears one
This is the detail I find genuinely startling.
Sumo's yokozuna — the grand champions — wear the shimenawa around the waist for the ring-entering ceremony.
Not a belt that resembles one. The rope, with the shide hanging from it, made the same way, meaning the same thing.
Which makes a yokozuna the only person in Japan formally wrapped as a yorishiro — as one of the objects a god can occupy.
He walks into the ring marked as a sacred site, in front of a crowd, on television, several times a year.
And it's half of the toolkit
There are two primitives in this tradition's defensive inventory, and they do different jobs.
The ofuda — the paper talisman — names the guardian. It says this household is under the protection of this deity. It's text, and it works by declaration.
The shimenawa — draws the border. It says the rule changes at this line. It's geometry, and it works by demarcation.
Text and shape. Between them they cover nearly every ward in the collection: you either declare who's protecting you, or you mark where the ordinary world stops.
And the shimenawa's version is the one you can see from a distance, which may be why it's the one that ended up on cedars, waterfalls, rocks, wrestlers, and every front door in the country each January.

Overview
The tradition keeps insisting on boundaries: the sealed pass of Yomi, the kimon corner, the birth-hut door. Japan's everyday embodiment of all of them is a rope: the shimenawa — laid rice-straw or hemp, hung with white shide zigzags — which marks "a ritually pure area," wards spirits, and wraps the yorishiro trees and rocks where kami dwell [wikipedia-shimenawa]. Our kodama entry's marked trees, every shrine's threshold, and the ground of every construction site before digging: one technology, drawn in straw.
The mythic origin (and it's the cave)
After Amaterasu was drawn from the Rock Cave (by ame-no-uzume's dance), the kami Futodama stretched a rope across the cave mouth "to avoid her returning" — the prototype shimenawa [wikipedia-shimenawa]. The first shimenawa was hung behind the sun — a boundary against the world going dark again. Every rope since repeats it.
The record
- Range: centimeters to monsters — Izumo Taisha's great rope: 13.5 meters long, 8 meters around [wikipedia-shimenawa], hanging over the shrine of the very province where Hearn counted foxes.
- The yokozuna: sumo's grand champions wear the shimenawa in the ring-entering ceremony [wikipedia-shimenawa] — a human marked as a sacred site; the only people in Japan formally wrapped as yorishiro.
- Function summary for the toolkit page: ofuda names the guardian; shimenawa draws the border. Text and geometry — the defensive inventory's two primitives.
