Aikido is a modern Japanese martial art developed by Morihei Ueshiba. It is based on traditional open hand and weapons arts, weapons training in Aikido traditionally includes the wooden sword, knife, and stick. Aikido techniques are based on movement, timing and balance. Beginning with entering and turning movements, we use the continuous flow of a circle, the angles of a triangle, and the stability of a square to create technique that is not dependent on physical superiority. Aikido techniques consist of entering and turning movements that redirect the momentum of an opponent's attack, and a throw or joint lock that terminates the technique.
