Anma (Kanji: 按摩 Hiragana: あんま) refers to both a practice of traditional Japanese massage and to practitioners of that art. Modern shiatsu is largely derived from anma. The seven traditional techniques are: pressing/stroking, grasping/kneading, strengthening, compressing, vibrating, tapping and "hand music".
Tokujiro Namikoshi Nov 3 1905-Sep 25, 2000 - the creator of Shiatsu. Though Shiatsu is more well known in the West, it is actually a 20th century modality. Namikoshi opened the Shiatsu Institute of Therapy in Hokkaido Japan in 1925.
