Find here an overview of possible workshops, developed and held by Barkas. In most cases Barkas is teaching together with Addie. In that case, Addie is model and co-teacher of the workshop and has to be named.

The list is to give an idea about the range of possible workshops. Each of those workshops can be transformed and combined with other workshops. Each workshop focuses on the people on both sides of the ropes, i.e. there is always a part devoted for rope bottoming skills.

All classes are hands on classes. The duration of each class can be booked from 90min up to 7h. The number of participants is only restricted in the suspension classes (12 couples max for safety reasons)

The language of the classes is either English or German.

Master class

A masterclass is a concept coming from music education. One student – one teacher and an audience of students. The focus of the teacher is completely on the student but the audience learns from watching the tuition. In principle, it is similar to a normal private tuition but the costs can be shared between all participants. Also, the participants can switch after one, two or more hours.

Prerequisites: dependent on the request


Beginners class

Japanese Rope Bondage can be erotic, artistic or whatever one puts into it. A main goal of tying with another person is to have a wonderful and interesting time with each other. This class gives a first insight in various principles of Japanese Rope Bondage. It enables the participants to tie some of the basic structures safely and with joy.


  • Historical overview
  • Physical and emotional safety
  • About ropes (length, diameter, material, basic handling)
  • Single wrist cuff and square knot
  • Double column ties
  • Bondage for sex
  • Bondage for bondage
  • Tips and tricks for Bottoming

Prerequisites: none. Ropes can be provided (in cases of larger events, please contact the organizer for providing ropes.)


Yukimura Ryu Newaza

Newaza, literally translated means “non-standing techniques”. Rope Bondage restricted to the floor, i.e. on a mattress or else, can be a very special way of experiencing ropes. The grand master Yukimura Haruki Sensei elaborated this style over the last 4 decades and established a system that enables students to learn his very unique style. Various techniques and a special handling of the human body are needed to increase the pleasure of tying on the floor. In this class, the participants learn how to use leverages and how to position their partner in certain ways with the use of ropes.


  • Positions on the floor and their stability/instability
  • Gote Shibari (a type of body harnesses)
  • Presentation of the partner and shame
  • Leverages
  • Kata Ashi zuri (one leg partial suspension)
  • Tips and tricks for rope bottoming by Addie

Prerequisites: Single column tie


 Takate Kote

This class shows the huge variety as well as the details of Takate Kote type patterns. It enables the participants to decide on their own how to modify a Takate Kote but still produce a safe, functional and esthetical pattern.


  • The mechanics of a Takate Kote type pattern
  • Necessities and unnecessities of a Takate Kote type pattern
  • Variations of a Takate Kote type pattern
  • Tips and tricks for rope bottoming by Addie

Prerequisites: Single & double column tie.


Suspensions. An Introduction

Suspensions (Jap: Tsuri/zuri) are spectacular and they can provide a complete new mind set to the tied as well as to the tying person. This class gives a first insight into the world of suspensions with a special focus on safety and communication.


  • Comments on safety and mechanics of suspensions
  • Material needed for suspensions
  • Uplines (Jap: Tsuri nawa)
  • Partial suspension (kata ashi zuri, i.e. one leg suspension with one leg still on the ground)
  • Yoko zuri (sideways full suspension)
  • Tips and tricks for rope bottoming by Addie

Prerequisites: Takate kote (no matter which as long as stable and sustainable)


 Suspensions. Advanced

Various other positions in suspensions with a focus on rope handling and smooth work. This enables the participants to use suspensions for different purposes within their play.


  • Aomuke zuri (face up suspension)
  • Gyaku ebi zuri (face down, legs bend to the back)
  • Sakasa zuri (head down/inversion)
  • Tips and tricks for rope bottoming by Addie

Prerequisites: Takate kote, Uplines


Suspensions. Transitions

The transition between two or more positions of a suspension is content of this class. The Osada Ryu among other schools pays a lot of emphasis on dynamics. Hence the steady movement of the tied person is central for a certain mind set. In this class we focus on the mechanics and the safety of the tied person as well as on a fluid handling of up lines.


  • Mechanical principles of transitions and rope handling
  • Yoko zuri progressions
  • Inversions
  • Making a plan
  • 360° transitions
  • Tips and tricks for rope bottoming by Addie

Prerequisites: Suspensions. Takate Kote.


In 2011, Barkas started to develop his personal way of doing ropes, which was very stormy and overwhelming. His Sensei Osada Steve called it ranboo and since then, this way of doing ropes became one of the well-known styles in the world of kinbaku. Within this class, the participants get a first insight into ranboo. Some key terms of ranboo, such as proper distance and proper intensity at the proper moment are the framework to tie in this way.


  • Key terms of Ranboo
  • How to start a scene
  • Madame Butterfly
  • Hojo Jutsu (some techniques to catch your partner)
  • Application of the principles of Ranboo
  • Tips and tricks for rope bottoming by Addie

Prerequisites: Single column tie.


The rope interview

The interview as a metaphor of tying. The interview combines the communication discourse with the one of power relationships. To tie with a person is always an involvement with a certain power relationship, simply and at least because of one person is tying and one person gets tied. But this scene also means a nonverbal conversation between the two people tying with each other. In this mind set we can think of an interview to describe the dynamics. With the help of some ipponnawa techniques we will explore some of the more obvious and some of the very subtle references to the interview metaphor.


  • Theoretical background of the approach
  • Different questions (that can be asked with ropes)
  • Different answers (that can be told to the questions)
  • Interpretations of answers
  • Tips and tricks for rope bottoming by Addie

Prerequisites: Single column tie


Differential Geometry for Rope Bondage

For people with a strong interest in mathematical, physical and engineering contexts of Rope Bondage. Reflecting on these contexts can help in understanding the structure of certain patterns. It also can help to increase the ability to handle the rope on a body.


  • Curved and flat spaces. A very short introduction into differential geometry.
  • Angles on curved spaces. Where to put the fingers when.
  • Knots and topological equivalence. Different “hitches” and their use
  • Forces and their direction. Frictions and suspension lines.
  • Tips and tricks for rope bottoming by Addie

Prerequisites: Single column tie

 Private Tuition

The focus is only on one student. In a private environment the student can work on various topics. Private tuition is also possible at a location chosen by the participant.

Private tuition can also include the participation of Addie with a focus on rope bottoming skills. It can also entirely focus on rope bottoming skills. In that case, Addie will lead the private tuition.

Contents as requested.

Duration as chosen by the participant. Max. 7h per day.

Prerequisites: dependent on the requests
