Shiatsu strives to address ailments and prevent their recurrence and development. Pressure applied by the thumbs to certain points of the skin stimulates the body’s natural recuperative powers and removes fatigue by causing the diffusion of the lactic acid and carbon dioxide that accumulate among the tissues to cause muscular stiffness and stagnation of the blood. The accumulation of fatigue increases pressure distortions in the accumulated fatigue throughout the body. This causes irregular internal secretions and peculiarities in the skeletal system and internal organs. By diffusing accumulated fatigue, Shiatsu pressure restores flexibility to the muscle tissues and relieves pain producing symptoms throughout the body.
There is a large number of places closely related to the functioning of the body organs and vessels. Shiatsu Therapy is mainly concerned with the 660 zones (tsubo) where blood vessels, lymph vessels, nerves, and the ductless glands of the endocrine system tend to concentrate or to branch. Although the tsubo points potency are invisible on the skin, they are nonetheless of the greatest importance. Namikoshi style Shiatsu has incorporated tsubo points into a systematized treatment that is based on physiology and pathology. Simply pressing on the body and stimulating a response is not enough to bring about a truly therapeutic effect. One must have a correct and accurate knowledge of the specific tsubo points and must know how to vary thumb pressure, patient’s position, and introduce movement to bring about a positive outcome.
