All-Japan Judo Championships
Draeger also participated in judo activities in Japan. For instance, in 1961, Draeger and British judo athlete John Cornish were the first non-Japanese athletes selected to demonstrate nage-no-kata during the All-Japan Judo Championships. Draeger became a member of the Nihon Kobudo Shinkokai, the oldest Japanese cultural organization for the study and preservation of classical martial arts. He was the first non-Japanese practitioner of Tenshin Shōden Katori Shintō-ryū, achieving instructor status ("kyoshi menkyo") in that system. He also held high ranks in Shindo Muso-ryu jodo, kendo, karate and aikido, among other arts.
