Prof. Sir Yoshiaki Sato M.D., Ph.D.,FNAI the inventor of KAATSU Training Methodology and Philosophy, was born on September 1948.

The inspiration for the KAATSU training method was originally received while he was attending a Buddhist memorial. He spent over forty five years studying and constantly refining the techniques of KAATSU Training.

He promotes the research and development business of KAATSU Training in the field of advanced medicine and space development through collaboration with five universities including Rutgers University (USA).



Prof. Sir Yoshiaki Sato started his own form of resistance training during his first year of junior high school. In the fall of 1966, on his last year at high school, he received the initial inspiration for KAATSU Training while attending a Buddhist memorial.

In later years, Prof. Sir Yoshiaki Sato has explained of his brief flash which was in fact the dawn of KAATSU Training. “I was sitting up straight on the floor listening to a Buddhist monk chanting sutra. My legs went to sleep and when I started massaging them I noticed a familiar feeling. I had been doing bodybuilding for six years by that point and the tightness felt similar to doing calf raises. I thought putting pressure on the calf must have made the muscle thicker. That was the spark.”

This initial flash of inspiration led Prof. Sir Yoshiaki Sato to repeatedly experiment on the application of pressure to various body parts in determining the muscle swelling or altered sensation associated with the reduced blood flow to the muscle. Four years later, he was able to complete the basic training manual on KAATSU Training.


In 1973, on a skiing trip with club members, Prof. Sir Yoshiaki Sato suffered serious injuries, fracturing both ankles and tearing cartilage and the medial collateral ligament of his right knee. While in casts, without heeding the doctors’ advice for caution, he began using KAATSU Training which resulted in his knee ligament surprisingly healing itself and fusing the bones. Thus, Prof. Sir Yoshiaki Sato accumulated the foundation and the methodology of KAATSU Training.


The amazing recovery from the serious skiing injury encouraged the professor to effect KAATSU Training as a means of rehabilitation. In his own words, Prof. Sir Yoshiaki Sato describes his personal observations, “an older wheelchair-bound individual regaining the use of his legs and another individual regaining sensation,” that made him realize his role in facilitating the healthcare burden across the nation.


KAATSU Training has become the focus of a great deal of interest in a variety of fields in the present world. It has developed to be a treatment from cardiovascular, orthopedic and immune system diseases to clinical depression and dementive disease.

Production of more of growth hormones (usually stimulated by heavy-weight lifting) while doing only low-intensity exercise is one key factor that differentiates KAATSU training from any other training regime. This low-intensity nature makes KAATSU training highly beneficial for those who are on rehabilitation and for the elderly users who can’t perform rigorous workouts. It is also considered a way of guarding against a great number of diseases associated with old age and promotes anti-aging itself.

Joint development research projects conducted by the KAATSU JAPAN Co.,Ltd and Japan Manned Space Systems Co. (which collaborates with Japan Aerospace Exploration Agency, JAXA) have progressed towards testing the use of KAATSU Training even in outer space. The research projects reveal that KAATSU Training increases muscle hypertrophy at low intensities and may help prevent the cardiovascular deconditioning associated with longer duration spaceflight.


Prof. Sir Yoshiaki Sato, by the end of 1994, applied for a patent on the KAATSU Training method in Japan. In June 1997, he received a patent from the Patent Office in Japan to protect and promote KAATSU Training valued as ‘high technological invention utilizing the laws of nature.’ The KAATSU Training method has obtained several patents in the United States and European Counties thereafter.

Today, a large number of people are actually undertaking some form of KAATSU Training in Japan. Based on the number of facilities across the country that offer KAATSU Training, the number of members at these facilities, the total sales of training-related equipment and other relevant data, it can be reasonably deducted that over 200,000 people in Japan are currently using KAATSU in some form or another, while the figure is growing by about 100 a month on the back of media coverage.


A few of the numerous joint research projects conducted by Prof. Sir Yoshiaki Sato M.D., Ph.D.FNAI include,

The University of Tokyo Hospital’s ’22nd Century Medical Centre’s Project (Sato Sports Plaza KAATSU Training: Division of Ischemia and Circulatory Physiology’ started at the University of Hospital in Oct 2004. The focus of the study is placed on,

  • Direct or secondary effects of KAATSU Training, and
  • The effects of KAATSU Training in comparison with that of traditional rehabilitation methods

Basic research on biochemical and molecular mechanisms associated with KAATSU Training (headed by Dr. Naokata Ishii of the University of Tokyo)

Applied research on the effect of acute KAATSU Training on Muscular Hypertrophy which could be used for prevention and rehabilitation (headed by Dr. Kenneth H., McKeever, Rutgers University, Equine Science Centre)

Medical research on the use of KAATSU Training for functional rehabilitation from cerebrovascular disorder (Dr. Yoshiharu Yokogawa, Shinshu University, School of Medicine)

Joint research between Japan Aerospace Exploration Agency (JAXA), University of Tokyo, and University of Tsukuba indicates that KAATSU Training could be used in-flight to balance oxygen levels and prevent economy class syndrome.


Books or jointly-edited books by Prof. Sir Yoshiaki Sato M.D., Ph.D, FNAI include the following;

  • All the Advantages of KAATSU TRAINING  (Edited by Association for KAATSU TRAINING instructors)
  • Miracle of KAATSU TRAINING (Kodansha)
  • Theory and Practical of KAATSU TRAINING (Kodansha)
