There is a polishing process in the Maki-e decoration making process in the Urushi crafts technique. In the Maki-e decoration technique, metallic powders are sprinkled on the surface of Urushi painting. After that, the powders are coated by another Urushi. When the Urushi is hardened, the surface of Maki-e is polished by a charcoal. Because this process affects a finish of Urushi crafts work, this research aimed to clarify a use of craftspeople body in the polishing process. Muscle function was measured with an electromyogram (EMG) in an expert and a non-expert. As the results, expert stabilized his shoulder joint, elbow joint and hand joint, non-expert did not stabilize their joints. Therefore, the expert can polish the Maki-e surface clearly, but the non-expert cannot do the same.
