Kanō Jigorō (嘉納 治五郎; 10 December 1860 – 4 May 1938) was a Japanese judoka, educator, politician, and the founder of judo. Judo was one of the first Japanese martial arts to gain widespread international recognition, and the first to become an official Olympic sport since 1964 (for men) and 1992 (for women), as well as the Commonwealth Games sport in 1990. Pedagogical innovations attributed to Kanō include the use of black and white belts, and the introduction of dan ranking to show the relative ranking among members of a martial-art-style. Well-known mottoes attributed to Kanō include "maximum efficiency minimal effort" (精力善用, seiryoku zen'yō) and "mutual welfare and benefit" (自他共栄, jita kyōei).
In his professional life, Kanō was an educator and a promoter of multiple sports in Japan, including swimming, athletics, weightlifting and other forms of physical education. Aside from judo, he is considered by some to be the originator of modern strength training in Japan. He also helped Gichin Funakoshi and other masters to introduce and systematize karate in the country. He was also a high member of the Dai Nippon Butoku Kai martial arts organization, and played a key role in making judo and kendo part of the Japanese public school programs. His cousin Kenji Kanō, founder of one of the first western boxing clubs in Japan, was also influenced by him.
Important postings included serving as director of primary education for the Ministry of Education (文部省, Monbushō) from 1898 to 1901, and as president of Tokyo Higher Normal School from 1900 until 1920. He was the educational founder of Nada Middle High School in Kobe, Japan. Accomplishments included being the first Asian member of the International Olympic Committee (IOC) (serving from 1909 to 1938), officially representing Japan at most Olympic Games held between 1912 and 1936, and serving as a leading spokesman for Japan's bid for the 1940 Olympic Games.
His official honors and decorations included the First Order of Merit and Grand Order of the Rising Sun and the Third Imperial Degree. Kanō was inducted as the first member of the International Judo Federation (IJF) Hall of Fame on 14 May 1999.
Kanō Jigorō was born to a sake-brewing family in the town of Mikage, Japan (now within Higashinada-ku, Kobe). The family sake brands included "Hakushika", "Hakutsuru", and "Kiku-Masamune". However, Kanō's father Kanō Jirōsaku (né Mareshiba Jirōsaku) was an adopted son and he did not go into the family business. Instead he worked as a lay priest and as a senior clerk for a shipping line. Kanō's father was a great believer in the power of education in the modern world, and he provided Jigorō, his third son, with an excellent education. The boy's early teachers included the neo-Confucian scholars Yamamoto Chikuun and Akita Shusetsu. Kanō's mother died when the boy was nine years old, after which his father moved the family to Tokyo. The young Kanō was enrolled in private schools, and had his own English language tutor. In 1874 he was sent to a private school run by Europeans, Ikuei Academy, to improve his English and German language skills. He was fluent in English, kept his diary in that language and wrote it in a very elegant style.
At the time of his adolescence, Kanō stood 1.57 m (5 ft 2 in) but weighed only 41 kg (90 lb). He was frequently bullied at Ikuei due to this small size and his intellectual nature, to the point other students sometimes dragged him out of the school buildings to beat him up, so he wished he were stronger in order to defend himself. One day, Nakai Baisei, a friend of the family who was a member of the shōgun's guard, mentioned that jūjutsu was an excellent form of physical training, and showed Kanō a few techniques by which a smaller man might overcome a larger and stronger opponent. Seeing potential for self-defense on this, Kanō decided he wanted to learn the art, despite Nakai's insistence that such training was out of date and dangerous. By the time Kanō moved to Kaisei Academy, his bullying had died off, but his interest in jūjutsu had not. His father also discouraged him from jūjutsu, as he ignored the bullying his son had suffered, but after noting Kanō's deep interest in the art, he allowed him to train on condition Kanō would strive to master it.
Kanō matriculated at Tokyo Imperial University in 1877 and graduated with a B.A. in Political Science and Philosophy in 1882. During his time at the university, he started looking for jūjutsu teachers. He first looked for bonesetters, called seifukushi. His assumption was that doctors who knew the martial art were better teachers. His search brought him to Yagi Teinosuke, who had been a student of Emon Isomata in the Tenjin Shin'yō-ryū school of jūjutsu. Yagi, in turn, referred Kanō to Fukuda Hachinosuke, a bonesetter who taught Tenjin Shin'yō-ryū in a 10-mat room adjacent to his practice. Tenjin Shin'yō-ryū was itself a combination of two older schools: the Yōshin-ryū and Shin no Shindō-ryū.
Fukuda's training method consisted mostly of the student taking fall after fall for the teacher or senior student until he began to understand the mechanics of the technique. Fukuda stressed applied technique over ritual form. He gave beginners a short description of the technique and had them engage in free practice (randori) in order to teach through experience. It was only after the student had attained some proficiency that he taught them traditional forms (kata). This method was difficult, as there were no special mats for falling, only the standard straw mats (tatami) laid over wooden floors.
Kanō had trouble defeating Fukushima Kanekichi, who was one of his seniors at the school. Therefore, Kanō started trying unfamiliar techniques on his rival. He first tried techniques from sumo taught by a former practitioner named Uchiyama Kisoemon. When these did not help, he studied more, and tried a technique ("fireman's carry") that he learned from a book on western catch wrestling. This worked, and kataguruma, or "shoulder wheel", remains part of the judo repertoire, although at this moment the judo organizations of some countries prohibit this throw in competition judo.
On 5 August 1879, Kanō participated in a jūjutsu demonstration given for former United States president Ulysses S. Grant. This demonstration took place at the home of the prominent businessman Shibusawa Eiichi. Other people involved in this demonstration included the jūjutsu teachers Fukuda Hachinosuke and Iso Masatomo, and Kanō's training partner Godai Ryusaku. Fukuda died soon after this demonstration, at the age of 52. Fukuda's students were not a large group, and among them Kanō was suitably skilled in randori and was clearly the most advanced in kata, and so Fukuda's widow chose Kanō to inherit the scrolls of his school. She also asked that the dojo remain open under Kanō's leadership, and he did assume this teaching responsibility for a time, but he soon decided that he should train more before accepting the duty of being a lead instructor.
Kanō began studying with Iso, who had been a friend of Fukuda. Despite being 62 years old and standing only 5 feet (1.52 m) tall, Iso had gained a powerful build from jūjutsu training. He was known for excellence in kata, and was also a specialist in atemi, or the striking of vital areas. In Iso's method, one began with kata and then progressed to free fighting (randori). Due to Kanō's intense practice and his solid grounding in the jūjutsu taught by Fukuda, Kanō became an assistant instructor at Iso's school. Iso Masatomo died in 1881. While under Iso's tutelage, Kanō witnessed a demonstration by the Yōshin-ryū jūjutsu teacher Totsuka Hikosuke and later took part in randori with members of Totsuka's school. Kanō continued to associate with students and teachers of the other schools of his era, and learned that Motoyama Masahisa, who was on a baseball team with Kanō and also was a graduate of the University of Tokyo, was the son of a master of the Kitō-ryū school. The senior Motoyama was now elderly and taught only kata, but Kanō had been seeking a teacher to train under actively after his previous teacher had died. Due to Kanō's persistence, Motoyama introduced Kanō to Iikubo Tsunetoshi as a more suitable Kitō-ryū master.
