Japanese Acupuncture

Tools of Japanese Acupuncture KM style

The Japanese style known as KM (Kiiko Matsumoto) is characterized by abdominal palpation, the use of reflex zones, shallow needling, and a unique set of tools. At Rivertown Acupuncture diode rings and diode chains, the pachi-pachi, triple bypass cords and ion cords may be used as part of a KM treatment.

A diode or semiconductor diode is a crystalline electronic component that can direct the body’s electric flow in one direction. By strategically placing a diode ring or a series of diodes in a silver chain (which can be wrapped around a limb), we can direct the body’s own energetic current toward healing.

Diode chains and rings are used in conjunction with triple bypass cords, which consist of a 3 cords ending with a red clip, green clip and black clip, the red and green each with a germanium diode. Because of the involvement of two diodes, an electric spark (provided by the pachi-pachi) is required, which in turn initiates a circular flow of therapeutic and gentle electric current, ideal for local treatments of stressed, inflamed or injured tissues, thyroid imbalances, arthritic joints, scars, neuropathy and repetitive stress injuries.

Ion Pumping Cords

Ion pumping cords were first developed by Dr. Manaka and then adapted by Master Kawai. It consists of a copper cord, one alligator clip on each side, and a special geranium diode attached to one clip. This device allows a flow of electric current in one direction only, which makes it a polarized treatment device. Therefore, the ion pumping cord is a powerful tool with strong therapeutic effect if applied knowledgably. They are used primarily to treat the extraordinary vessels, our deepest level channel system, as well as extremely painful conditions such burns of first and second degree, wounds and traumatic injuries.


Magnets can be used as part of a primary treatment, instead of needles, with children or particularly fearful people; or they can play an adjunct role, to prolong treatment. As an adjunct, magnets of 800 guass may be placed on the ears or at relevant channel or trigger points after the treatment. Tapping the magnet periodically will propagate a vibration that will stimulate the  As part of a primary treatment, we use strong magnets, usually 3,000 guass, which are placed on the points and then stimulated with the Manaka hammer and dowel. This is accomplished by placing the wooden dowel against the magnet and striking it rhythmically, creating a vibration that enters into and stimulates the channel point.
