About Aunkai – frontpage

Aunkai – Overview

Aunkai is a method of training the body and mind according to the fundamental principles that govern human movement. As the body develops and absorbs these physical principles, it can begin to act in accordance with martial principles.

“Technique” is only a product of a body that has been trained to intuitively understand the most natural and efficient ways to move in a martial context.

There are many different interpretations of the word “training.” At Aunkai, we first recognize our preconceptions and notions, then attempt to tune the body through certain training methods in order to discover movement of the human body that is in accord with certain principles.

Our focus is on the creation and usage of a martial body. We have members with backgrounds in many different styles such as Karate, Aikido, Muay Thai, MMA, etc. Anyone from any style is accepted here at Aunkai.

There are many who pursue the daily practice of bujutsu (or budo) as a means to temper their spirit. Training in bujutsu, or performing bujutsu tanren is one way of knowing yourself both physically and mentally.

Through the development of a body suitable for bujutsu, forging it in a manner according to the principles that are the foundation of bujutsu, absorbing and learning how to use the body through contact training and finally through the never ending cycle of experimentation/innovation we seek to create a core within our bodies that is jutsu. That is the purpose of tanren.

The Aunkai bujutsu class does not place any emphasis on repetition of empty movements or techniques. Instead, we aim to give our students the physical tools to forge a bujutsu body able to bring its own imperfections to light, address them, and come to its own answers—all of this eventually leads the practitioner down their own path in the Martial Way. To do this, we follow roughly the curriculum outlined below:

  1. Creating Foundation: Realization of principles within the body.
  2. Contact Training 1: How to use forces against an opponent.
  3. Contact Training 2: Sanda, sparring, etc.
  4. Bujutsu: Applications of the above.
