Koichi Tohei Sensei was awarded the highest rank (10th degree blackbelt) by Aikido Founder Morihei Ueshiba (O-Sensei) in 1969. After O-Sensei's death, Tohei Sensei continued as Chief Instructor of the Aikikai.

Through understanding the principles of mind and body unification, Tohei Sensei had very clear ideas about the best way of teaching Aikido. These ideas were largely influenced by Nakamura Tempu Sensei and Tetsuju Ogura Sensei, two formative teachers of our Founder (Soshu) Tohei Sensei.

Tohei Sensei introduced a system of teaching Ki. In 1971, Tohei Sensei founded the Ki no Kenkyukai. Its purpose is to teach the principles of Ki and realization of mind and body oneness.
