Gusukuma’s 3 Karate Principles

Sensei Gusukuma’s 3 principles

Grand Master Seikichi Iha’s first instructor the infamous Shinpan Gusukuma outlined the three foundational principles of karate as kata, jutsu, and gyaku. Without all three, the martial application is lost.

Kata is the foundational form by which the body develops proper posture, breathing, balance, flexibility, and unified muscle/tendon/hip control for maximum outpower.

Jutsu encompasses the bunkai, or analysis of the martial techniques; only some of which are derived from kata. Over time, these techniques become muscle memory. Almost all kata movements have multiple bunkai, but bunkai is not limited to kata analysis nor the bunkai of curriculum.

Gyaku is the “reverse”, or the continuous counter-application to the bunkai. It is represented in the spontaneous free-flowing of movements as counters to attacks. Oyo bunkai in the curriculum is a baby step toward gyaku; moving from block printing to cursive, yet still within the “wording” of kata. Gyaku is free composition based upon the “theme” of kata.

Sensei Iha reminds us that it is the responsibility of the dedicated student to seek out partners for the exploration of jutsu and gyaku. There we find the joy of exploration.
