Gensuke Yoshida, known in English-language judo records as George Gensuke Yoshida, was an Issei judo instructor who played an important role in establishing and teaching judo in New York. According to records associated with the ISSEI portrait collection, he was born in Saga Prefecture in 1895 and came to the United States in 1917.
English-language histories of American judo associate Yoshida with one of New York’s earliest judo organizations. The New York Judo Club was reportedly established in 1919, during a period when judo was still little known in the United States, and Yoshida was later named among its instructors. Former students and practitioners more commonly remembered the institution as the New York Dojo, with Yoshida serving as its head instructor.
Yoshida attained the rank of shichidan, or seventh-degree black belt. His name appears in the United States Judo Federation’s directory of high-ranking practitioners as “Yoshida, Gensuke G.,” associated with New York. This high rank reflects his long experience and standing within the American judo community.
The influence of Yoshida and the New York Dojo extended well beyond the prewar Japanese immigrant community. Virginia Mayhew, who later became one of the earliest prominent women in American aikido, studied judo under Yoshida for approximately five years. Richard “Dick” Hugh, another important figure in postwar American judo, also recalled visiting Yoshida’s New York Dojo during the 1950s.
Students continued to remember Yoshida’s teaching decades later. , described it as one of the leading judo clubs in the country and credited Yoshida with teaching both technical ability and humility. Such recollections suggest that Yoshida regarded judo not simply as a competitive sport or method of self-defense, but as a discipline through which students developed character, respect, and self-control.
His life represents an early and important chapter in the transmission of Japanese martial arts to New York, connecting the traditions brought by Japanese immigrants before World War II with the broader growth of American judo in the postwar decades.
