Aikido is a martial art that was developed in the early part of this century by Morihei Ueshiba, who synthesized various elements of ancient Japanese martial techniques. His self-defense system allows control of an attacker with minimum use of force, and his training methods promote mental self-control and physical flexibility, endurance and vigor. Aikido is typically practiced in pairs or groups. In addition to techniques using open hand, rolls and throws, Aikido also teaches the use of the wooden sword (bokken) and staff (jo).

Iaido is the art of drawing the katana, or Japanese sword. It is not a combative art but a formal discipline of well-defined kata, or forms. Iaido may only be studied with the permission of the chief instructor.
