The History of KAATSU and How KAATSU Came About

For who? Competitive athletes, Baby Boomers, KAATSU users
For what? Strength, stamina, functional movement, hormonal response, balance, skin elasticity

Professor Sir Dr. Yoshiaki Sato, MD, PhD of Tokyo, Japan is the inventor of KAATSU.

This video summarizes the history of KAATSU until 2010. The video explains how KAATSU can improve blood circulation, stimulate a significant hormonal response, and improve muscle tone.

KAATSU was invented in 1966. The KAATSU Cycle was invented in 1973. Its research at the University of Tokyo began in 1995 with Naokata Ishii, PhD. Dr. Sato filed his first patent application in 1993 and the first patent was issued in Japan in 1997 and the first United States patent was issued in 2000. The first scientific paper on KAATSU was published by the Journal of Applied Physiology in 2000.

The KAATSU products have been engineered and designed in Southern California since 2014 while the initial testing and research were conducted by Dr. Sato and cardiologists Dr. Toshiaki Nakajima and Dr. Toshihiro Morita at the University of Tokyo Hospital (with over 7,000 cardiac rehab patients between 2004 and 2014). The physicians studied, tested, researched and set the protocols at the 22nd Century Medical Center in the Department of Ischemic Circulatory Physiology, Kaatsu Training, University of Tokyo.

The carefully controlled, narrow, elastic, easy-to-use pneumatic KAATSU bands automatically and safely optimizes blood circulation for muscle tone, strength, mobility, rehabilitation, and recovery.

KAATSU devices (KAATSU Master 2.0, KAATSU Cycle 2.0, KAATSU C3, KAATSU B1) included a handheld automated compressor and universal pneumatic, stretchable bands which are placed around the arms or legs. Arm bands and leg bands are used separately during each session.

The KAATSU Air Bands inflate and deflate in a patented sequence based on algorithms that are optimal for each user, no matter their age or physical abilities. KAATSU protocols are convenient, easy-to-do, and time-effective. KAATSU equipment offer unparalleled performance, precision, and safety for users of all ages, fitness levels, and walks of life – and can be used anywhere anytime to help people…

Recover Faster, Rehab Stronger and Perform Better

The primary differences between KAATSU and other BFR bands is:

  1. KAATSU utilizes the patented Cycle function
  2. different pressures can be simultaneously used on different limbs, including the option of doing Single-Limb KAATSU
  3. KAATSU equipment and protocols were proven safe and effective after a decade of clinical use and research on over 7,000 cardiac rehab patients at the University of Tokyo Hospital (between 2004 and 2014)
  4. KAATSU is used by cardiologists, orthopedic surgeons, podiatrists, and physicians in various specialties as well as physical therapists, chiropractors, trainers and coaches
  5. KAATSU Air Bands do not occlude arterial flow
  6. KAATSU is meant to be gentle and convenient in order to do anywhere anytime
  7. KAATSU is used worldwide by people up to the age of 104
  8. more research has been conducted in more countries on KAATSU than any other BFR device
  9. the seminal, groundbreaking research on BFR was conducted and published by KAATSU inventor Dr. Yoshiaki Sato in the 1990s
  10. KAATSU Air Bands are waterproof and the KAATSU C3 is ruggedized for military applications
