About Us

Kokikai Aikido is a modern Japanese martial art that teaches coordination of mind and body using self-defense techniques to develop one's strongest state. Classes include both men and women practicing on equal footing. Designed to defend against multiple attackers, it is an effective form of self-defense that offers many solutions to aggressive behavior by others.

As a member of our dojo, you will learn to derive maximum effect from minimal effort. Regardless of your gender, strength or size, you will discover how to harness your attacker’s energy, master techniques to stop attacks, neutralize opponents, and safely avoid conflict with grace, agility and dynamic power.
