The Major Osada-Ryū Kyu Exams for Europe

Next examination date: November 07, 2026

Admission is free!

What the examination is

Osada-Ryū is the rope school of Osada Steve Sensei and enables students to learn Shibari (also known as Kinbaku or bondage) from the ground up.

The structure of the school is strongly inspired by systems such as Kendo or Aikido. Therefore, Osada-Ryū also has so-called Kyu levels, ranging from 9 to 1. For Europeans, it may be confusing, as it does not start at Kyu 1 but at Kyu 9.

Our students go through these individual Kyu levels, where they learn and train very specific topics, and can then present what they have learned at the grand examination.

The greatest challenge of this examination is not mastering the techniques, but facing the examination itself—and remaining present for the person in the ropes despite the pressure.

Examination procedure

The examination is led and conducted by the instructors. Vinciens from Vienna (from the dojo "Kinbaku Studio Vienna") is the highest-ranking instructor in Osada-Ryū and leads the examination. Ibinuphis (Markus) and Jack (André) support the process.

On this examination day, all students from all Kyu levels take part. The Kyu levels are divided into groups, and these groups take the examination together. For example, Kyu levels 9, 8, and 7 are tying at the same time with the assigned topics.

The examination lasts between 2 and 3 hours per student. During this time, Vinciens assigns the tasks that need to be demonstrated.

The audience

Osada-Ryū originates from performance-based rope work. For this reason, the audience is an important element of this style. The tying is also focused on presenting the person in the ropes and highlighting beauty and aesthetics.

To honor this aspect, we invite spectators to the examination. These are usually other Kyu students who are not taking the exam, friends, relatives, partners, or people interested in Osada-Ryū who want to see how the examination works.

Spectators are asked not to disturb the students during the examination.

Vinciens explains the tasks given to the students to the audience, including background information about the individual ties. This helps viewers better understand the purpose and origins of the ties, giving them a deeper perspective.

After the examinations

After the examinations, Vinciens, Ibinuphis, and Jack withdraw and review each participant, discussing the presented elements and whether the exam was passed.

Once everything has been discussed, the three return and the diploma ceremony begins. The diploma certifies that the student took the exam and met all the requirements for passing. It lists the kyu level tested and the names of the examining instructors. Each instructor adds their personal hanko (seal) to the certificate as a ‘signature.’ The certificates are then handed out individually to the students.

The day concludes with a shared meal, where participants can exchange experiences and enjoy time together with like-minded people.

Where is the Aijō Dojo located?

The Aijō Dojo is located at Niederlenzerstrasse 29, 5600 Lenzburg, Switzerland. Workshops, training sessions, jams and private lessons usually take place there. The location for each event is shown with the current dates.

How is the dojo equipped?

The dojo has a tatami area, a large timber frame with eight suspension points, a seating area and an entrance area for clothing, drinks and snacks. Outside training hours, the space is also used as a photo studio. You can find more details on the dojo page.

What role do consent and personal boundaries play?

Consent, communication and respect for personal boundaries are the foundation of every activity at Aijō Dojo. Agreements apply before, during and after tying, and boundaries can be communicated again at any time. At jams and other open formats, other people or sessions must never be involved without being asked.

What is a Ryū?

The word Ryū is derived from ryūha (流派), which means school, style or manner. In martial arts, it is customary to name the founder first and use Ryū as a suffix (-流, -ryū).

The structure is strongly influenced by Japanese martial arts. This means starting at Kyu 9 and progressing to Kyu 1.

Who are these kyu training sessions and exams intended for?

Those who decide to take kyu training and then the corresponding exams want to focus specifically on kinbaku/shibari, particularly Osada ryu. The kyu training is designed to provide a solid foundation in the basics of kinbaku/shibari.

It is a clearly defined path, divided into nine levels (3 basic levels, 3 intermediate levels, and 3 advanced levels). These are dedicated to different topics and thus show a clear path for learners to acquire, improve, and develop their Shibari skills. The basic level is for beginners who have no prior knowledge of Shibari. The intermediate level is for those who have already acquired basic knowledge and skills in Shibari. The advanced level is for those who have already acquired advanced knowledge and skills in Shibari.

Through testing and intensive repetition, the Kyu also offer experienced riggers the opportunity to test their own level. In the process, carelessness in detail is corrected, thus consolidating and improving one's own style.

What requirements must I meet for the kyu examinations?

Both beginners and experienced practitioners can start Kyu training. Everyone begins at the same level.

Admission to an examination requires focused work on the content of the respective Kyu. The necessary knowledge is taught in practical lessons through exploring, experiencing and learning each focus topic rather than through books or videos. Watching and discussing are just as important as active tying. The duration and scope of preparation vary according to experience. However, the desired level cannot be reached without additional practice outside the training sessions.

What distinguishes Kyu training from other types of training?

Kyu training is based on a clearly structured curriculum tailored to the respective level. Learners work intensively with the defined topics for the Kyu they are pursuing. While the curriculum provides the overall direction, the specific exercises and learning content remain flexible and can be adapted individually.

How long does it take before I can take a kyu exam?

The number of training hours depends on the rigger's level of knowledge and their individual learning speed. As the kyu level increases, so does the intensity of the preparation in order to meet the requirements. As a rough guideline, approximately 10 hours of training can be planned for the lower kyu levels. However, the focus is not on the speed at which the exams are taken, but rather on intensive study of the restraints and topics of each kyu level. The journey is the destination.

Can I practise other styles and ties alongside Kyu training?

Yes. How closely someone wishes to follow the path of Osada-Ryū is a personal choice. Other styles and individual development remain possible. Regardless of style, safety, consent and responsible rope practice must always be respected.

Who conducts the examinations?

Only an officially licensed instructor may conduct the examinations. We therefore collaborate with Vinciens from Kinbaku Dojo Vienna and Secret56. Vinciens is the highest-ranking instructor in Osada-Ryū and leads the major examination event, which takes place once a year.

Aijō believes that learners should not be examined by their own teacher. The examination is therefore conducted by another instructor, while Jack attends in his role as teacher.

Do I have to take the exams?

In general, there is no obligation to take the exam. However, without passing the exam, the student may not claim to have achieved a kyu level. This is only possible after passing the exam.
