Jigoro Kano

Jigoro Kano (1860–1938) was the founder of Judo, a leading educator in modern Japan, and a pioneer of the Olympic movement in Asia. His best-known achievement was transforming older jujutsu traditions into Kodokan Judo. Yet his larger ambition was educational: he wanted physical practice to build knowledge, character, health, and a sense of responsibility toward other people.

Why Kano matters

Kano is often introduced as “the father of Judo.” That description is correct, but incomplete. He was also a school leader, a writer, an organiser of physical education, an advocate for international learning, and Japan’s first representative on the International Olympic Committee. His work connected the dojo with the classroom, and Japanese traditions with a wider world.

Early life and education

Kano was born on 10 December 1860 in Mikage, near present-day Kobe. His family was connected with the prosperous sake-brewing and shipping culture of the Nada region. As a child, he received a demanding education that included Chinese classics, calligraphy, English, and other modern subjects. He later studied at institutions that became part of the University of Tokyo.

Although he was academically gifted, Kano was small and physically slight. Wanting to become stronger and to understand how a smaller person could handle a larger one, he began studying jujutsu while he was a university student. He trained in several traditions, most importantly Tenjin Shinyo-ryu and Kito-ryu. This combination of close study, personal need, and broad education shaped the way he later approached martial arts.

From jujutsu to Judo

In the early Meiji period, many people viewed traditional martial arts as relics of the past. Kano saw something else in them: a powerful method for physical training, moral education, and practical problem-solving. He studied what made techniques work, removed or restricted methods that could not be practised safely at full intensity, and organised training around repeated, cooperative learning.

In 1882, Kano founded the Kodokan in a small twelve-mat room at Eisho-ji temple in Tokyo. The first group was tiny, but the project quickly grew. Kodokan Judo kept the technical heritage of jujutsu while giving it a new purpose. The shift from jutsu, meaning technique or art, to do, meaning a way of life, was central to Kano’s vision.

Two principles for practice and life

Seiryoku Zenyo — best use of energy

Seiryoku Zenyo is commonly translated as “maximum efficient use of energy.” In Judo, it means using balance, timing, preparation, and technique instead of wasteful force. Kano believed the principle applied far beyond a throw or a hold. Students should develop their minds and bodies, then use their abilities wisely in study, work, and society.

Jita Kyoei — mutual welfare and benefit

Jita Kyoei means “mutual welfare and benefit.” Judo partners cannot improve without one another: each person attacks, responds, falls, protects, and helps the other learn. Kano made this a social principle as well. Personal success is incomplete if it does not also support the well-being of other people and communities.

A modern system for learning

Kano created the kyu-and-dan ranking system, including the familiar distinction between white and black belts. The system made progress visible and gave learners clear stages to work toward. It was later adopted and adapted by many other martial arts around the world.

He also helped standardise the judogi, the strong white uniform used for training. More important than the uniform or the belt was Kano’s teaching method: careful fundamentals, safe falling practice, free practice called randori, formal kata, and thoughtful reflection on what practice teaches. His early students—including Shiro Saigo, Sakujiro Yokoyama, Yoshiaki Yamashita, and Tsunejiro Tomita—helped demonstrate and spread Kodokan Judo in Japan and abroad.

Education beyond the dojo

Kano spent much of his life in education. He taught at Gakushuin, led several important secondary schools, and served for more than two decades as principal of Tokyo Higher Normal School, the predecessor of the University of Tsukuba. He argued that education needed three connected dimensions: intellectual learning, moral development, and physical education.

At a time when physical education was often treated as secondary, Kano promoted swimming, running, gymnastics, outdoor activity, and teacher training. His work helped establish physical education as an essential part of modern schooling in Japan. He also recruited outstanding teachers, valuing ability and curiosity over narrow conventions.

International education and exchange

Kano’s internationalism was practical as well as philosophical. He supported students from China who came to Japan during a period of rapid modernisation and founded schools that provided Japanese-language and general education. The best known was Kobun Gakuin, which educated thousands of Chinese students. Among those associated with this network was the future writer Lu Xun.

This work expressed Jita Kyoei on an international scale. Kano believed that learning across borders could strengthen both the individual and the wider region. He treated education as a long-term form of cooperation rather than a competition between nations.

Judo travels the world

Kano travelled widely and sent skilled teachers overseas. In the United States, Yoshiaki Yamashita taught at Harvard University and introduced Judo to President Theodore Roosevelt. In Latin America, Kano’s student Mitsuyo Maeda became a famous travelling judoka. Maeda’s teaching in Brazil influenced the Gracie family and forms part of the historical background to Brazilian Jiu-Jitsu.

This story shows how an art can change as it travels. In Japan, Kano continued to frame Judo as education and self-cultivation. Abroad, different communities adapted its techniques to their own questions about self-defence, sport, and grappling. The shared roots remain an important link between Judo and Brazilian Jiu-Jitsu today.

Women and Judo

Kano opened opportunities for women to learn Judo at a time when women’s participation in strenuous sport was often discouraged. The Kodokan women’s section was formally established in 1926. Its early programme was shaped by the social assumptions of its era and focused strongly on kata and controlled study, but it created an important foundation for later generations of women judoka.

The Olympic movement

In 1909, Kano became the first Asian member of the International Olympic Committee. He founded the Japan Amateur Sports Association in 1911 and led Japan’s first Olympic team to Stockholm in 1912. For Kano, the Olympic movement was a way to encourage international understanding through education and sport.

He also worked tirelessly to bring the 1940 Olympic Games to Tokyo, believing that an Olympic Games outside the Western world could create a meaningful meeting between cultures. Tokyo was awarded the Games, but Japan later gave them up as war expanded. Kano died from pneumonia aboard the ship Hikawa Maru on 4 May 1938, while returning from an IOC meeting. The 1940 Games never took place; Tokyo eventually hosted the Olympics in 1964, when Judo made its Olympic debut.

Kano welcomed international exchange, but he was cautious about reducing Judo to medals and national rivalry. He hoped that sport would remain connected to education, ethical growth, and benefit for society.
