The roots of shiatsu
I guess it depends on how narrow we want to define the word shiatsu. Technically the word was coined in the early part of the 20th century. It is hard to pin down exactly when but it was certainly in use by 1919 when Shiatsu Ho (finger pressure method) by Tamai Tempaku was published. Tempaku is most often credited with the creation of modern day shiatsu. He first used the word shiatsu in an effort to distinguish it from anma, as he considered the traditional form of Japanese body therapy was losing its emphasis on health and being mainly used for pleasure and relaxation.
