Shin Shin Toitsu Aikido (心身統一合氣道) or Ki Aikido (氣 合気道) is a Japanese martial art, a gendai budo (contemporary martial art). It is part of the martial arts derived from aikido, which appeared after its founder's death in 1969. It started in early 70's with the creation of the Ki Society of Koichi Tohei,[1] the previous Aikikai's Chief Instructor. This martial art focuses on mind and body coordination and is based on aikido techniques and Japanese yoga and promote non-violent conflict solving and self-development.[2]
He was taught Shinshin-tōitsu-dō (also known as 'Japanese yoga') by Tempu Nakamura. He felt that Tempu Sensei's teaching and explanation made clear what Morihei Ueshiba was able to do in his aikido (particularly the idea that the mind moves the body). As a result he started bringing in exercises from Shinshin-tōitsu-dō, such as 'unbendable arm' and 'unraisable body' into his aikido teaching. He started to do this as Chief Instructor of the Aikikai, while Morihei Ueshiba was still alive. He also felt the concepts of Shinshin-toitsu-do were more clearly applicable to daily life. It was later that he formalised his style, including leaving out some aikido techniques that he felt were ineffective against a partner who could coordinate mind and body. Although Tohei Sensei gave the Ki Development aspect of his style the name Shinshin-toitsu-do, it only covered part of Tempu Sensei's curriculum/teaching, and some of it was modified by him.
The teaching of Ki Aikido has been split between different federations, each reflecting the experience of their founders: Ki Society with Koichi Tohei and his son Shinichi Tohei,[3] Ki no Kenkyukai Internationale Association with Kenjiro Yoshigasaki[4] and Ki Federation of Great Britain with Ken Williams (or Kenneth Williams).[5][6]
