Katsukuma Higashi was a Japanese jujutsu practitioner who established himself as a New York-based jiu-jitsu expert in the early 1900s. He practiced Tsutsumi Hozan-ryu jujutsu — not Kodokan judo, despite his book's title. He collaborated with writer H. Irving Hancock on 'Jiu-Jitsu Combat Tricks' (1904) and 'The Complete Kano Jiu-Jitsu' (1905). On April 6, 1905, he fought catch wrestler George Bothner in New York for three hours but lost. On November 29, 1905, he fought Yukio Tani in Paris for the 'world jiu-jitsu championship' — the match ended controversially. After Paris, he traveled to Germany and vanished from the historical record entirely. His real name and fate remain unknown.
