Kata principles

The three fundamental principles of kata empasized by Mas Oyama

 

技の緩急  Waza no Kankyū  

The Relative Tempo of Techniques:

The tempo of the kata varies – some techniques are performed quickly, while others are done more slowly.

 

力の強弱  Chikara no Kyōjaku  

The Relative Force of Power:

The power of a technique derives from the proper balance between strength and relaxation.

 

息の調整  Iki no Chōsei   

The Control of Breathing:

The correct timing (inhaling and exhaling) and force of the breaths (Kiai 気合, Ibuki 息吹 or Nogare 逃れ) are essential for proper techniques.
