Dojin

A keiraku (meridian) doll used for training in acupuncture. The doll is marked with 14 energy paths and pressure points. The keiraku doll originates from the Chinese dojin doll. The dojin doll is scarved with energy paths and pressure points, and is devised that when the acupuncture needle hits the pressure points, mercury seeps out. According to records, these dolls were brought to Japan during the Muromachi period, but Japan began making their own keiraku dolls with the spread of acupuncture therapy in the beginning of the Edo perod and they became widely sued in general practices.
