Unlike other shibari styles built around predefined figures or patterns, Sekibaku places the practical usefulness of the rope within the erotic interaction as its central technical criterion.
From the perspective of erotic experience, one cannot assume that the same rope figure or pattern will be stimulating for everyone, regardless of their tastes or circumstances.
Accumulated experience—our own and with students—confirms that sticking to closed patterns can be demotivating and often creates frustrations that make it hard to establish a suitable erotic context.
At Shibari Dojo we therefore take a different approach: the study of the technical fundamentals and of the physics involved in applying rope to a body under restraint. Under this paradigm, the function of the rope is to secure the anatomical restraint and to offer support to the person being tied.
We are not tying an inert object, but an active person: the aim is not to immobilize them, but to heighten their stimulation and desire through restraint.
Developing skills progressively
Acquiring the manual skills needed for advanced rope handling takes time, practice and dedication.
Mastery of the technique by the person tying is a condition for the safety, efficiency and flow of the erotic interaction—and we are fully aware that not everyone can devote the necessary time and energy.
That is why training is structured in modules: each step builds on the previous one, so that each person can apply the techniques they have mastered with full effectiveness, safety and satisfaction, without having to complete stages that are beyond their skills or simply don’t interest them.
Confidence is born of that safe, efficient application—and from confidence, freedom within the session.
Many students tell us they are uncomfortable with suspensions: these are techniques they have not mastered and that carry a high risk. You don’t need to go there. No one should feel pressured to operate beyond their real capabilities.
Rope techniques
Taking the principles of the Yagami Ryu as a reference, these are the techniques that make up nawasuji (繩筋):
Sabaku (さばく)
Sabaku is the way the rope is handled: how it moves, how it is guided.
The first principle, and the one that breaks the most preconceptions, is that the rope is handled with an open hand. The person tying does not grip the rope when holding or moving it.
The hands manage the fine movement, allowing a smooth, steady pass of the rope that gives the person being tied subtle information about what is happening and what is coming.
This is not about “communicating through the rope”—rope doesn’t talk and has no signal—but about giving gentle cues on the body of the person being tied (fureru, 觸れる).
Choryoku (張力)
Choryoku is not tightening: it is the parameter that establishes the connection between the body of the person being tied and the tie.
The tension in the rope (nawa no choryoku, 繩の張力) must match the tension of the body (karada no choryoku, 體の張力), and body activation (haru chikara, 張る力) must adapt to the specific moment of the session.
You don’t need the same activation sitting on the floor as jogging up a flight of stairs.
When that match is established and the path of the rope supports the kinetic circuits between the person tying and the person being tied, the rope works like a tendon: it makes it possible to handle the body of the person being tied from the tie. A voluntary movement, but an induced one.
Kata (型)
Although the overall approach rejects preset figures in erotic interaction, kata are used as study tools: to learn specific techniques or to link several together.
They are not chosen at random, but for their usefulness in integrating theoretical and technical elements in a functional, safe and aesthetic way.
The basic forms we work on, in order, are:
- Hon Musubi (本結び): an interpretation of the single column.
- Ikue Shibari (幾重縛り): a deconstruction of the traditional gote.
- Tasuki (襷): a dorsal sash.
- Koden Shibari (古傳縛り): the first basic form of the Yagami Ryu; it combines body handling (tenbindori) with rope tension and direction.
- Kaeshinawa Shibari (返繩縛り): the second basic form of the Yagami Ryu; it works with a single rope over a gote structure.
- Futomomo (フトモモ): a single-leg tie.
- Jimon cho (自問蝶): a neck tie—choker style—that combines body technique with tension management. Its advantage is that it allows a neck tie to be done safely, but that safety comes from correctly applied technique: imitating it without knowing it can be dangerous.
Those familiar with Yagami Ren’s style will have noticed that two iconic forms are missing: Ipponshibari (壱本縛り) and Wakizarashi (脇晒し). This is a deliberate decision. The first is not taught at the first level because of its danger. The second is not dangerous, but a significant share of students have mobility problems that prevent it from being established safely.
Modes of application
Rope technique does not consist in replicating sequences as if following a manual, but in combining them freely according to the interests and circumstances of each moment. On top of the techniques comes a layer of intention and management, divided into two branches:
- Shoden Keito (初傳系統): the strict mode, which guides the person being tied clearly and firmly in tempo and intensity.
- Toginawa Keito (伽繩系統): the fluid mode, which relies more on the reactions of the person being tied than on one’s own intentions.
In practice, the immediate goal is more concrete: understanding rope handling, tension and two or three of the forms listed is already a solid, sufficient foundation for responsible, satisfying practice.
There are no shortcuts here. These are manual skills that take time and dedication, and we know that is not always possible. But we trust in each person’s ability to act responsibly and stay within the limits set by their real skills.
This is what matters: it is not about getting anywhere, completing a complex process or making the result look like someone else’s or like a photograph.
The only purpose of erotic shibari is the satisfaction of desire—that of each participant—safely and from a place of mutual responsibility.
