We are Alexander (NawaRonin) and Natasha NawaTaNeko. Kinbaku and especially Seme-nawa in the style of Akira Naka has become an important and enriching part of our lives. We share our passion by performing and teaching Kinbaku together.

Alexander is a scientist and researcher, thinker and explorer and since a long time fascinated by Japanese history and culture:

Kinbaku is a journey for me, a path I walk with my partner and a few close people, people whom I trust to open up to. Kinbaku happens between two people, it is communication and emotion – and highly erotic. I am interested in playing with sensations to induce emotions: suffering, pain and pleasure … in beauty. When I tie then that’s definitely a challenge for the person in my ropes.

Natasha is a truth seeker and embodiment enthusiast. In Kinbaku, she is looking for true emotions and authenticity and sees rope bondage as deeply intimate and erotic practice that has also a profound transformational potential:

I love rope for that it’s honest. Real. Tangible. With rope, you can learn to surrender, you can learn integrity. You can learn to be generous – and grateful. If you engage in a rope play – I mean really engage, with the full heart, it will inevitably transform you. I’m into a challenge of two people coming close, very close together, a challenge of exchanging a gift of a focused attention and connection, becoming vulnerable in showing themselves as they are and letting other see them.

After a long phase of experimentation with different teachers and styles, we found our home and gave our hearts to Seme-nawa as taught in Europe by Riccardo Wildties, the first disciple (Deshi) of Akira Naka. Alexander is the first official certified instructor for Kinbaku Luxuria Naka Ryo Basic Level (Zero to TK) in Germany.

As a Kinbaku teachers, we strive to empower our students as quickly as possible to find their own path. We teach principles and elements, not fixed, rigid forms. Alexanders’ background as a scientist and Martial Art practitioner as well as his teaching experience from his day job feed into our teaching method.

Building on her background in Sexological Bodywork by Joseph Kramer and her studies of “Wheel of Consent” by Betty Martin, Natasha brings different somatic aspects as breathing, movement, posture, non-verbal communication, and placement of attention in our teaching. She developed “Somatics for rope bottoms” to deepen their experience in ropes and make it more internal, conscious and safe.

We offer workshops and private classes in Berlin, and we are open for invitations to teach, perform and share our way of Kinbaku in other communities outside of Berlin.
