​About acupuncture

What are acupressure points?

In Oriental medicine, it is believed that energy, known as "qi" and "blood," circulates throughout the body via pathways called "meridians," sustaining vital functions. Points along these meridians, like stations, are called acupoints (tsubo). When the flow of energy through the meridians becomes stagnant, various ailments appear in the body. Sometimes pain, sometimes temperature changes, and sometimes sweating may appear along the meridians, and these are signs of dysfunction in the organs located along that meridian. Acupuncturists assess the state of the acupoints along the problematic meridian to understand the internal ailments, and then stimulate those points using needles or moxibustion to regulate the circulation of qi and blood, leading to improvement of the ailments.

The human body has a total of 394 acupuncture points: 361 points known as the regular meridians and extraordinary meridians, and other points known as the extraordinary points. Including the number of points that appear as reaction points (Ashi points), the total number is even greater. So, what exactly are acupuncture points? In recent years, it has become clear that acupuncture points are primarily located in important areas such as vital nerves and fascia (muscles, blood vessels, and tissues). Western medicine also recognizes that ailments appearing at acupuncture points are related to dermatomes on the body surface, where internal organ dysfunction manifests as sensory disturbances in areas of the skin innervated by the same nerves. Evidence for acupuncture points is accumulating year by year, deepening our scientific understanding.

The World Health Organization (WHO) published a list of 43 diseases for which acupuncture is indicated in 1979, and achieved international standardization of acupoint names and locations in 2008. Currently, research and clinical practice of Oriental medicine are actively developing in many countries under the category of traditional medicine, and Oriental medicine as a whole is attracting considerable attention. Although Japan lags behind other countries, the number of hospitals and medical institutions incorporating Oriental medicine is increasing year by year, and it is achieving results, particularly in improving the quality of life for terminally ill cancer patients.

About the needles used

We use sterilized, disposable needles. We select the needle depending on the treatment area and the patient's condition, but the needles we use are as thin as a strand of hair, with a diameter of 0.14 to 0.34 mm. Comparing a 20G (0.9 mm diameter) injection needle used in hospitals with a No. 3 acupuncture needle (0.20 mm), the injection needle is 4.5 times larger in diameter, and its cross-sectional area is 20 times larger (4.5 x 4.5 = 20.25). Also, the tip of an injection needle is designed to cut sharply, but acupuncture needles are rounded, so there is almost no pain or bleeding. In addition, silicone-coated needles are becoming mainstream, further reducing pain during insertion to the greatest extent possible.
