Kokikai
Kokikai is an
aikido style, founded by
Shuji Maruyama. The organisation is called
Kokikai Aikido International.
The Kokikai style emphasizes natural movement, ki development, relaxation, good posture and mind-body coordination. It is a minimalist martial art that focuses on making techniques effective while using little physical effort. An axiom of the style is "minimal effort for maximum effect." The name Kokikai means "school of radiant ki".
The style lists four basic principals: Relax progressively, Keep one point, Positive mind and Correct posture
The style was founded by Shuji Maruyama (referred to as Maruyama Sensei, or just Sensei), and continues to be led by him. He continues to develop the art, so there is no set textbook way of performing any technique.
