Yoshihiro Uchida (born April 1, 1920), better known as Yosh Uchida, is an American judo coach, businessman, entrepreneur, and educator who is best known for his contributions to judo. Uchida has been the head judo coach at San Jose State University for over 70 years, and has played a leading part in the development of the university's judo program. His brother George Uchida was the 1972 US Olympic judo coach. He turned 100 in April 2020. Early life Uchida was born in the Imperial Valley town of Calexico, California, to Japanese immigrants who worked as farm laborers. Later growing up in Garden Grove, Uchida began competing in judo at age 10. Uchida studied biology at San Jose State, and in 1940 was made the student-coach of the Physical Education Department's judo program. During World War II, while members of his family were sent to internment camps, Uchida was drafted into the United States Army during World War II and served as a medical technician. He returned to San Jose State in 1946 to complete his degree and to restart the judo program. Judo career After graduating in 1947, Uchida remained the coach at SJSU, a part-time position, while working as a laboratory technician at O'Connor Hospital and then a lab supervisor at San Jose Hospital. During this time, Uchida and University of California, Berkeley judo coach Henry Stone began developing rules to allow their students to compete against each other, including a weight class system, moving judo away from a martial art for self defense to a sport for competition. Stone and Uchida persuaded the Amateur Athletic Union (AAU) to sanction judo in 1953; the first AAU National Championship in judo was held at San Jose State in that year. From 1960 to 1961, Uchida served as president of the Judo Black Belt Federation of America, which under his leadership started a pilot program for a national ranking system. With United States Air Force Academy (USAFA) judo coach Phil Porter, Uchida co-organized the first National Collegiate Judo Championship in 1962 at USAFA. Uchida's San Jose State Spartans won the first of their over 40 national championships under his leadership at the inaugural tournament. Uchida represented the United States as the team coach of the first Olympic Judo Tournament at the 1964 Summer Olympics in Tokyo. The team included two of Uchida's students from San Jose State, Ben Nighthorse Campbell and
