The Japanese martial art of Aikido was developed by Morihei Ueshiba (known
as O'Sensei, or "great teacher") during the twentith century. His unique approach
to the martial arts was to emphasize blending with, instead of opposing, an
attacker's energy. Following World War II, Aikido's popularity increased when
O'Sensei stressed the peaceful applications of the martial art. One of O'Sensei's
principal students was Koichi Tohei, who began studying under the founder in
1939.
After the war, Tohei Sensei was picked by O'Sensei to bring Aikido to the United States, which he did starting in 1953 by introducing the martial art to Hawaii, where it flourished. Tohei Sensei became Chief Instructor under O'Sensei, and was eventually promoted to 10th Dan (10th degree black belt), the highest possible rank.
After O'Sensei's death in 1969, Tohei Sensei stayed on as Chief
Instructor of the Aikikai under the direction of the O'Sensei's son, Doshu Kisshomaru
Ueshiba Sensei. The two eventually parted ways over disagreement in teaching
style. Tohei Sensei developed a teaching system which taught Ki principles to
all students, which he felt would make their Aikido techniques stronger, and
also allow them to use Ki development in everyday life. In 1974, Tohei Sensei
left the Aikikai and founded the Ki Society International, which is the organization
underwhich the Virginia Ki Society operates.
The main focus in Ki Aikido is on remaining calm and alert, using inner energy (ki) rather than muscle power alone.
