The Shibari Glossary: Every Rope Term Explained

Every word you will hear in a rope room, and what it actually means

People arrive at sessions carrying vocabulary they collected from forums, reels, and a friend who did a workshop once. Half the words contradict each other. Some are Japanese used loosely. Some are English inventions that never existed in Japan. Some are titles that mean one thing in Tokyo and something else entirely in Berlin.

This is the reference I keep for myself. Terms as they are actually used, grouped by what they describe, with the places where usage splits marked as such.

No tutorials here. A glossary explains language. Ties are learned with hands, in a room, with someone watching.

1. The words for the thing itself

Shibari (縛り)
From shibaru, to tie or to bind. In Japanese it is an ordinary word. You can shibari a bundle of newspapers. Outside Japan it became the umbrella term for the whole erotic rope practice, which is why Japanese practitioners sometimes find its Western usage slightly odd.

Kinbaku (緊縛)
Tight binding. This is the term Japanese practitioners use for the erotic tradition specifically. If someone insists on kinbaku over shibari, this is the distinction they are making.

Kinbaku-bi (緊縛美)
The beauty of tight binding. The aesthetic dimension, treated as its own subject.

Hojōjutsu (捕縄術)
The martial art of restraining prisoners with rope, used by feudal-era Japanese law enforcement. Frequently cited as the origin of kinbaku. The lineage is real but looser than the internet suggests: hojōjutsu was functional and non-erotic, and the erotic form developed much later, through the twentieth century, via theatre, photography, and the magazine Kitan Club.

Nawa (縄)
Rope. It appears inside dozens of compound terms.

Semenawa (責め縄)
Torture rope, or more accurately rope that applies suffering. A whole school of practice built on duration, intensity, and the receiver's endurance. Associated above all with Naka Akira. Semenawa is not aggression. It is a slow, sustained pressure that the receiver is invited to stay inside of.

Newaza (寝技)
Ground work. Borrowed from judo. Everything that happens on the floor, without suspension.

2. Schools, lineages, and styles

Japanese rope is transmitted through lineages the way martial arts are. Ryū (流) means school or current.

Yukimura-ryū
After Yukimura Haruki. Intimate, close-body, minimal rope. Often described as seduction rope: the tie stays close to the receiver, the rigger's body stays close to the tie. Fewer wraps, more contact.

Naka-ryū
After Naka Akira. The reference point for semenawa. Precision, stillness, and endurance.

Osada-ryū
After Osada Steve, a Tokyo-based practitioner who built one of the first structured teaching systems accessible to non-Japanese students. Much of what is taught in Europe traces back through here.

Akechi Denki, Nureki Chimuo, Arisue Go, Kazami Ranki, Hajime Kinoko, Kanna
Names you will hear cited as lineage or influence. Kinoko in particular sits apart, working in large-scale installation and performance where rope becomes environment rather than restraint.

Western rope bondage
The parallel tradition. Different logic: often symmetrical, engineering-minded, built around named knots and reproducible structures. Not a lesser form. A different one.

Fusion
Japanese forms with Western hardware, Western frictions, or Western structural thinking. Most European practice is fusion whether or not it says so.

Somatic or therapeutic rope
The newest branch, and the one closest to what I do. Rope used as a tool for nervous system regulation and attention rather than as an aesthetic or a scene. Sometimes overlaps with bodywork and trauma-informed practice. The vocabulary here is still forming, which is both its weakness and its interest.

3. The rope itself

Asanawa (麻縄)
Hemp rope. The traditional material.

Jute
The most common rope in contemporary practice. Lighter than hemp, more textured, with a smell people either love or complain about. Requires conditioning: stripping, oiling, singeing the fuzz.

Hemp
Softer against skin than jute once broken in, heavier, holds tension differently. Preference between the two is genuinely personal.

MFP, nylon, POSH
Synthetics. Washable, slippery, unforgiving under load in different ways. Common for beginners and for anyone who needs rope that survives a laundry machine.

Cotton
Soft, cheap, stretches. Fine for floor work, poor for suspension.

Standard rope
Roughly seven to eight metres, five or six millimetres in diameter. A set of six to eight ropes covers most floor work.

Bight
The folded midpoint. Where almost every Japanese tie begins.

Nawajiri (縄尻)
The rope end. Also, in older usage, the tail a captor held.

Tenugui (手ぬぐい)
A thin cotton cloth. Blindfold, gag, or padding.

Bamboo, ring, hardpoint
The suspension apparatus. A hardpoint is the anchor in the ceiling or frame. Its rating matters more than anyone's technique.

4. Ties and structures

Japanese names describe the body, not the knot. This is the single most useful thing to understand: the vocabulary is anatomical.

Gote (後手)
Hands behind the back. The umbrella family of arms-behind ties.

Takate-kote, usually TK (高手小手)
High hand, small hand. The chest harness with the arms bound behind. The most photographed tie in the world and the most dangerous one for the radial nerve. Treated as the foundation of the practice and, correctly, as the tie that takes longest to earn.

Hishi (菱)
Diamond. The lattice pattern.

Hishi karada
The diamond body harness. In the West it is usually just called a karada, which is a small mistranslation, since karada (体) simply means body.

Munenawa (胸縄)
Chest rope.

Koshinawa (腰縄)
Hip or waist rope. Historically the prisoner's waist line.

Matanawa (股縄)
Crotch rope.

Futomomo (太腿)
Thigh. The tie that folds calf to thigh and binds them together.

Ebi (海老) and gyaku ebi
Shrimp, and reverse shrimp. Ebi folds the body forward into a compressed seated position and is a classic semenawa form. Gyaku ebi arches it backwards.

Agura (胡坐)
Cross-legged. The seated tie.

Teppo (鉄砲)
Rifle. A single-arm form.

Hashira shibari (柱縛り)
Pillar tie. Binding someone to a column, a post, a bedframe.

Tasuki (襷)
Over the shoulders, from the cord traditionally used to hold back kimono sleeves.

Kannuki (閂)
The bolt, as in a door bolt. The wrap that cinches a bundle of rope perpendicular to itself and stops it from spreading.

Nodome
The stopper. What holds tension where you left it.

Frictions
The Western word for the structural crossings that hold a tie together without a knot. X-friction, Somerville bowline, Burlington, Munter. A tie built on frictions can be released fast, which is the point.

Single column, double column
Western nomenclature. A column tie binds one limb; a double column binds two together. Universally taught as the first thing anyone learns, and rightly.

5. Suspension

Tsuri (吊り)
Hanging. Suspension.

Semi-tsuri
Partial suspension. Part of the body remains supported by the ground. Most of what looks like suspension in photographs is partial.

Full suspension
No contact with the floor. Every point of load passes through rope, through the receiver's tissue, and through the hardpoint.

Uplines
The lines running from the tie to the ring, carrying the weight.

Transition
Moving between positions while suspended. The most technically demanding moment and the one where things go wrong.

Kata ashi tsuri (片足吊り)
One-leg suspension.

Yoko tsuri (横吊り)
Side suspension.

Sakasa tsuri (逆さ吊り)
Inverted suspension. Head down.

Predicament
A structure that forces the receiver to choose between two uncomfortable options. Their own body maintains the tension.

6. Roles and titles

Nawashi (縄師)
Rope master. A title of craft, conferred rather than claimed. In Japan it carries real weight. Anyone who gives it to themselves on an Instagram bio is telling you something.

Bakushi (縛師)
Binder. The more modern professional term for someone who ties, particularly in performance.

Rigger
The Western word. Functional, borrowed from theatre and climbing, with an engineering flavour that says a lot about the difference between the two traditions.

Rope top, rope bottom
Neutral English, currently the most widely used pair. Says nothing about gender, dominance, or lineage.

Rope bunny
Common, affectionate, and disliked by a good number of the people it describes. Ask before using it about someone.

Uke (受け) and seme (攻め)
Receiver and giver, borrowed from martial arts and used in some Japanese-lineage contexts.

Model
Performance-specific. A rope model is a collaborator in a public piece, not a passive surface.

Switch
Someone who ties and is tied.

7. Safety

This is the section where precision stops being aesthetic.

Radial nerve
Runs along the upper arm. The most commonly injured nerve in rope, almost always from a TK. Compression produces wrist drop: the hand hangs, the fingers cannot extend. Recovery ranges from hours to many months.

Ulnar and median nerve
Also at risk, generally through the forearm or wrist.

Nerve check
The standing test. Grip strength, making an OK sign with thumb and forefinger, extending the wrist against resistance. Repeated during the tie, not just after it. Numbness, pins and needles, or loss of motor function means the rope comes off immediately.

Circulation versus nerve
Cold, blue, and slow to refill is circulation, which is uncomfortable and usually tolerable for short periods. Numbness and loss of movement is nerve, which is urgent. Confusing the two is the most common beginner error.

Positional asphyxia
Restricted breathing caused by body position rather than anything around the throat. The reason a tied person is never left alone. Ever.

Safety shears
EMT shears, within reach, always. Rope you cannot cut is rope you cannot end.

Negotiation
The conversation before. Limits, health history, medication, injuries, what is available and what is not.

Safeword and safe signal
A word, and a non-verbal alternative for when speech is gone. Holding an object and dropping it. Two taps. Sound rather than language.

RACK, SSC, PRICK
Risk-Aware Consensual Kink. Safe, Sane, Consensual. Personal Responsibility, Informed Consensual Kink. Three frameworks for the same question, with different levels of honesty about the fact that this activity carries risk.

Aftercare
What happens after the rope is off. Warmth, water, food, contact, quiet. Not optional, and not only for the person who was tied.

8. What happens in the body

Rope space
The altered state that comes from sustained restriction, pressure, and focused attention. Time distorts. Language recedes. Not the same as arousal, and often unrelated to it.

Subspace, topspace
The broader BDSM terms for the equivalent states on either side.

Float
The period after, when the nervous system is still elsewhere.

Drop
The crash that can follow, hours or days later. Flat, tearful, cold, inexplicable. It happens to tops as well as bottoms, and knowing the word for it in advance is most of the protection against it.

9. Rooms and etiquette

Rope jam
An open practice session. Bring rope, tie, be watched, watch.

Peer rope
Practice between equals, without teaching hierarchy.

Dojo
Used loosely in Europe for a regular teaching space.

Nawakai
A rope gathering, usually invitation-based.

Show
A performed piece, generally choreographed to some degree, generally with a model who has agreed to every element in advance.

Unwritten rules
Do not step on rope. Do not touch someone else's rope. Do not touch a tied person you are not tying. Do not photograph without asking. Do not interrupt a scene, and if you think something is going wrong, speak to the person running the room rather than to the rigger.

10. What everyone confuses

Shibari and kinbaku. Shibari is the generic word for tying. Kinbaku is the erotic tradition. In practice, outside Japan, the two are used interchangeably and nobody will correct you.

Nawashi, bakushi, rigger. Nawashi is a conferred title. Bakushi is a profession. Rigger is a job description. Most people tying rope in Europe are riggers.

Gote and TK. Gote is the family of arms-behind ties. The takate-kote is one member of it. All TKs are gote; most gote are not TKs.

Karada and hishi karada. Karada means body. The diamond harness is hishi karada. The West dropped the first half of the name.

Suspension and partial. If a foot is on the ground, it is partial. This distinction matters when someone tells you what they have done before.

Semenawa and rough rope. Semenawa is slow, controlled, and intensely attentive. Speed and force are not what makes it difficult.

Hemp and jute. Different plants, different weight, different feel. Neither is more authentic.

Shibari and BDSM. Rope exists inside BDSM and also entirely outside it. Plenty of rope practice involves no power exchange, no dominance, and no sex at all.

Trust and safety. They are not the same thing. Trust is what the receiver brings. Safety is what the rigger is responsible for building. Trust does not compensate for an untested hardpoint.

None of these words make a tie safer. They make the conversation possible before the tie happens, which is a smaller thing than it sounds. After the conversation there is still only your hands, someone else's nervous system, and whatever you are actually able to notice.
