In the year 1900, aged twenty, Uyenishi travelled to
London at the invitation of
Edward William Barton-Wright, the founder of the eclectic
martial art of
Bartitsu. Soon after his arrival in London, Uyenishi joined fellow expatriate Japanese wrestler
Yukio Tani on the teaching faculty of Barton-Wright's Bartitsu Club in
Shaftesbury Avenue. Tani and Uyenishi also began to distinguish themselves as professional wrestlers, competing successfully against much larger opponents in the contests promoted by Barton-Wright. After the Bartitsu Club closed down (circa 1902), Uyenishi continued his work as a professional wrestler and also taught jiujitsu classes at the
self defence academy that had been established by his former Bartitsu Club colleague,
Pierre Vigny. His abilities as a teacher were often remarked upon, and by 1903 he had established his own dojo, the School of Japanese Self Defence, at 31 Golden Square,
Piccadilly Circus. Uyenishi adapted enthusiastically to life in
Edwardian London society. He was an exotic "character" whose stylish dress-sense and gentlemanly bearing were considered noteworthy by several interviewers. In 1905, with the assistance of his student E.H. Nelson and writing under his professional wrestling alias of "Raku", Uyenishi produced his
Text-Book of Ju-Jutsu, which became a popular reference work. Within, his credentials were listed as: "Instructor to the following Colleges in Japan: Riku-gun yo-nan gako (The Military College for Officers); Tai-iku-kai (The Imperial Military College of Physical Training); Shi-han-gako (The School of Instructors); Jun sa ki-shun-sho (The Police Training School); All Government Schools in Osaka; And to The Army Gymnastic Staff, Headquarters Gymnasium, Aldershot". Three years later, while continuing his wrestling as a sideline, Uyenishi was also employed as a
hand-to-hand combat instructor at
Aldershot Military School and at
Shorncliffe Army Camp. During the period of 1907–8, Uyenishi embarked on a highly successful professional tour of Spain, Portugal and other European countries, teaching jiujitsu classes and performing exhibitions and challenge matches with local wrestlers. == Return to Japan and death ==
