Yukio Tani was cross ranked by Kano as a 2nd degree black belt in Judo when Kano visited the Budokwi in the early 1920's, many years after Tani made his reputation as a fighter in the music halls of England.

E.W. Barton-Wright is also remembered as pioneering the promotion of mixed martial arts. He held contests, in which experts in different fighting styles compete under common rules. Barton-Wright’s champions, including Yukio Tani, Sadakazu Uyenishi and Swiss schwingen wrestler Armand Cherpillod enjoyed considerable success in these contests. Again way ahead of his times since it would be nearly 100 years later when these competitions would rise in popularity again.
