In earlier days in China, a doctor wasn't paid to give treatment to ill people but to keep a person healthy. As soon as a person became ill, he got his treatment for free. The health care was basically preventive. There are 5 types of treatment: acupuncture, medicines and herbs, curving with stones, moxa and anma (massage). Shiatsu came from anma. It was recommended for people living in the center of the country, near to the yellow river. In this area the culture was most developed and people were doing more mental than physical work. The same can be said about us.
The Japanese took many things from Chinese culture to change and develop. So they did with anma and acupuncture and developed it into "shiatsu".

Shiatsu is a Japanese form of massage therapy similar to acupressure; in fact, the word shiatsu literally means "finger pressure." As with acupressure, the concepts of shiatsu hold that it can promote health and facilitate healing by correcting energy imbalances in the body. These imbalances are corrected by applying pressure to specific points along channels in the body known as meridians. While there is no exact date as to when shiatsu originated, the technique is believed to be hundreds, if not thousands, of years old.

Shiatsu is usually delivered with the thumbs. However, some practitioners will use their fingers, palms, elbows -- and even feet -- to achieve the desired effect. Typically, a shiatsu practitioner will apply pressure not just to a few points on the body. The goal here is twofold: to release energy (qi in Chinese, ki in Japanese - pronounced "chee") in areas where it may be blocked or stagnating, and to bring energy back to areas that are depleted.

In addition to applying pressure, shiatsu practitioners may manipulate the soft tissue over and around meridians, and perform passive and active stretching exercises as part of treatment. Scientifically speaking, shiatsu is an excellent form of pain relief. Research has shown that applying extensive pressure initiates the release of endorphins, natural pain-killing substances produced by the body. Shiatsu may also lower the levels of adrenaline and other stress hormones, producing a relaxing effect.
