Aikido represents the highest expression of Japanese Budo (or martial arts). It is not only an effective (if not the most effective) form of self-defense, it is also strongly based in a moral perspective almost unknown in the world today. The idea is that there two basic forms of thought in the Japanese martial arts - "satsujinken" and "katsujinken" (the sword that kills and the sword that preserves life). The SWORD? Yes, you will learn more about this later, but
suffice it to say that almost all Aikido techniques are based on sword technique although Aikido is usually performed empty-handed. You will learn about this and much more in the classes.

Whenever I move, that's Aikido. 
O-Sensei, Morihei Ueshiba

 Aikido is a Japanese martial art developed by Morihei Ueshiba (often referred to by his title 'O Sensei' or 'Great Teacher'). On a purely physical level it is an art involving some throws and joint locks that are derived from jiu-jitsu and some throws and other techniques derived from kenjutsu. Aikido focuses not on punching or kicking opponents, but rather on using their own energy to gain control of them or to throw them away from you. It is not a static art, but places great emphasis on motion and the dynamics of movement.

Upon closer examination, practitioners will find from Aikido what they are looking for, whether it is applicable self-defence technique, spiritual enlightenment, physical health or peace of mind. O Sensei emphasised the moral and spiritual aspects of this art, placing great weight on the development of harmony and peace. "The Way of Harmony of the Spirit" is one way that "Aikido" may be translated into English. This is still true of Aikido today, although different styles emphasise the more spiritual aspects to greater or lesser degrees. Although the idea of a martial discipline striving for peace and harmony may seem paradoxical, it is the most basic tenet of the art.
