Classical Japanese Acupuncture uses needles that are very fine and sit close to the skin’s surface so people typically don’t feel any pain during a treatment. You may feel subtle sensations at the location of the needle or along your meridians.
One of the differences to Chinese Acupuncture, a different form of acupuncture, is that they use thicker needles and deeper insertions than Classical Japanese Acupuncture.
The main difference is that Classical Japanese Acupuncture looks for the cause of your symptoms, but treats you to get you healthy and free of Dis-ease.
