Koichi Tohei was born 1920 in Shitaya ward (下谷区), presently Taitō, in Tokyo. As a boy he was sickly and frail, leading his father to recommend Tohei for judo studies. He trained hard and his body prospered, but soon after he began his pre-college studies at Keio University, he developed a case of pleurisy. This forced Tohei to take a year off.

Tohei was distressed at the thought of losing his newfound strength of body and his means of training it, so he decided to replace his judo studies with Zen meditation and misogi exercises, learned at the Ichikukai Dojo in Tokyo. As with his judo studies, Tohei entered the training of the mind with fervor and soon excelled despite his serious health issues. After his recovery from pleurisy, Tohei became convinced that it was his efforts in training his mind and cultivating his ki that had helped him to heal and recover. This stimulated his later development of Kiatsu, a system of treating physical illness by pressing with the fingers and extending the ki into the ill persons body. Tohei describes this as “priming the pump” allowing the person to heal themselves.

After recovering from pleurisy he returned to judo, but Tohei wanted more than just physical training and did not think that judo was the right art for him to practise, although he did continue studying judo until he started aikido.

In 1940, when he was 19, Tohei’s judo instructor, Shohei Mori, recommended that Tohei meet with the founder of aikido, Morihei Ueshiba.

According to Tohei, when he first met with an aikido instructor and practised some techniques at the Ueshiba dojo, he had doubts about aikido and its value to him. That changed when Ueshiba entered the dojo and started to perform his techniques on the instructors. Tohei was still not entirely convinced until Ueshiba asked Tohei to step onto the mat and try to grab him. Tohei’s attempts were unsuccessful, and after this personal demonstration by Ueshiba, Tohei asked to enrol on the spot. Tohei continued to train his mind as well as his body with meditation, misogi and aikido.

Tohei trained with Ueshiba for six months before being sent as a representative (dairi) to teach at the Shumei Okawa school and the military police academy. This was before Tohei was ranked as either dan or kyu. Ueshiba presented Tohei with the rank of 5th dan after Tohei had begun his military service.

War years

In 1942, Koïchi Tohei graduated from the Economics Department of the prestigious Keio University. In february of 1944, after receiving military training, Tohei Sensei was sent leading an infantry unit into occupied China. There he understood, under enemy fire, the importance of calming one’s mind in the One Point in the lower abdomen (“seika no itten”). Because of the lack of doctors, Tohei developed during the war the principles of what he later named Kiatsu Therapy, based on sending Ki through the fingertips. He saw action in China and was stranded there at the end of the war until his repatriation in 1946. Tohei Sensei stated on several occasions that Ki principles such as “extend Ki” and “relax completely” leaving things up to the Universe helped him to stay safe during the war, as well as the eighty men under his command.

Post-war years

Beginning in 1953 Koïchi Tohei Sensei was responsible for the introduction of aikido to the West, mainly through regular teaching journeys to Hawaii, but also continental US and Europe. It was the first time the Founder of aikido allowed for the art to be taught outside of Japan. For that reason, Hawaii became a center for diffusion of aikido in the United States, and remains today an important place for Ki-Aikido. During his years at the Aikikai, Tohei Sensei taught aïkido to many famous Shihan like Hiroshi Tada, Sadateru Arikawa, Seigo Yamaguchi, Shigenobu Okumura, Kazuo Chiba, Yoshimitsu Yamada and Steven Seagal.

In 1969, Tohei was asked by Ueshiba to accept the new rank of 10th dan, which Tohei accepted, after having previously refused the same offer. The top rank in aikido had been 8th dan, but the ranks were expanded by Ueshiba for practical as well as political reasons.

Creation of the Ki no Kenkyukai

The events leading up to the split between the main aikido organization, the Aikikai, and Tohei were fueled with the death of Morihei Ueshiba in 1969. His son Kisshomaru Ueshiba inherited the title of Doshu. At the time of Ueshiba’s death, Tohei was chief instructor of the Hombu Dojo, the headquarters of Aikikai, a title he retained until his official split from Aikikai in 1974.

One of the major causes of the conflict arose from Tohei’s emphasis on his principle of ki in aikido. Tohei wanted aikido to focus on these principles, using exercises to both cultivate and test ki in the daily aikido practice. He had already started teaching his new ideas during his own training sessions at Hombu dojo, but the majority of the other instructors would not. There were some who agreed with Tohei’s approach, but Tohei’s actions were not welcomed by Kisshomaru and most of the senior instructors. They strongly encouraged him not to teach his principles and techniques in the Hombo Dojo. Tohei replied that he had the right to teach it outside Hombu Dojo, which he did.

But the tensions remained among the senior cadre of instructors, who still did not approve of Tohei’s focus upon ki. These brewing tensions together with Tohei’s general dissatisfaction with the situation culminated in 1971 when he created the Ki No Kenkyukai, with the purpose of promoting the development and cultivation of ki inside aikido, but outside the Aikikai “umbrella”. The years of conflict finally cemented Tohei’s decision to break away from the Aikikai and teach his own ‘ki’ style of aikido. On 1 May 1974, Koichi Tohei officially left the Aikikai organisation to concentrate on his newly created Ki-aikido and Ki-society.

On 15 May, 1974, Tohei sent a letter in English and Japanese to the majority of the dojos both in Japan and abroad, explaining his reasons for the breakaway and his plans involving Ki-aikido and the Ki-society. This breakup came as a shock to many aikidoka throughout the dojos of the world. Tohei was well regarded by many instructors and students. He was seen as the foremost sensei of Aikido after Ueshiba’s death. This, in turn, led to several dojos breaking with the Aikikai and joining Tohei in his new style. Tohei’s new objective was to coordinate all the dojos who joined him and incorporate them into the organisation of Shin Shin Toitsu Aikido: “Aikido with Mind and Body Coordinated”. This branch of aikido is still active today even though Tohei himself retired from the day-to-day business of the Ki-aikido section and then concentrated solely on the Ki-society and further personal development of ki.

Tohei Sensei died on May 19, 2011.
