Koichi Tohei

For many years, until the death of O-Sensei, Master Koichi Tohei, 10th Dan, was the Chief Instructor at the Headquarters of Aikido in Tokyo, Japan. Shortly after O-Sensei's death, Master Tohei founded Ki Society International (Ki No Kenkyukai). His goal was to spread the principles of Ki and Aikido throughout the world. In 1975, he established Shin Shin Toitsu Aikido (Aikido with mind and body unified).
