Shiatsu (指圧 Japanese from shi, meaning finger, and atsu, meaning pressure) is a traditional hands-on therapy originating in Japan. There are two main Shiatsu schools: one based on western anatomical and physiological theory and the other based on Traditional Chinese Medicine (TCM). Shiatsu is regulated as a licensed medical therapy by the Ministry of Health, Labour and Welfare (Japan), and elsewhere by various governing bodies set up by Shiatsu practitioners. Shiatsu is an evolving form, and its various styles incorporate (to differing degrees) aspects of Japanese massage traditions, Chinese Medicine practice, and "Western" anatomy and physiology.
