The name Aikido is composed of three Japanese words: ai, meaning harmony; ki, spirit or energy; and do, the path, the system, or the way. Aikido is the way of the spirit of harmony.

Martial arts are studied for self-defense and self-improvement but Aikido is different from other martial arts in that the practitioner seeks to achieve self-defense without injury to attackers.

The basic movements of Aikido are circular in nature; most attacks are linear. The Aikidoist harmonizes with, rather than confronts, an aggressive line and converts it into a circular motion that renders attackers helpless. Then, instead of using potentially crippling kicks or punches, the Aikidoist trains to apply various wristlocks, arm pins, or unbalancing throws to neutralize aggressors without serious injury.

Aikido is not a sport. There are no competitive tournaments. The Aikidoist betters his or her self without belittling others, and because Aikido seeks not cause harm, techniques can be practiced at full power without fear of injury. Aikido is the newest of the traditional Asian martial arts, hold the most modern outlook, and is proud of its high ideals.
