Understanding Judo's history helps you appreciate its principles. Jigoro Kano, the founder of Judo, transformed ancient martial techniques into a modern system of physical education and moral development. His vision created not just a martial art, but a way of life.

The Young Kano

Jigoro Kano was born on October 28, 1860, in Mikage, a small coastal town near Kobe, Japan. He was the third son of a prosperous sake brewer. Despite his intellectual gifts, young Kano was small and physically weak, often bullied by his peers.

At age 17, when Kano moved to Tokyo to attend university, he stood only 5'2" and weighed about 90 pounds. Determined to strengthen both body and spirit, he began searching for a jujitsu teacher. This was not easy—by the late 1870s, jujitsu schools were disappearing as Japan rapidly modernized and Western culture became fashionable.

Learning Jujitsu

Kano eventually found teachers from two prominent jujitsu schools. His first teacher, Hachinosuke Fukuda of the Tenjin Shin'yo-ryu school, emphasized throwing and pinning techniques. Fukuda's teaching philosophy was simple: learn by doing. Students were thrown repeatedly until they understood how techniques worked through their own bodies.

After Fukuda's death, Kano continued training under Masatomo Iso, also of Tenjin Shin'yo-ryu, who specialized in atemi-waza (striking techniques) and katame-waza (grappling techniques). When Iso passed away, Kano sought out Tsunetoshi Iikubo of the Kito-ryu school, which excelled in nage-waza (throwing techniques) and emphasized principles over brute force.

The Birth of Kodokan Judo

In 1882, at just 21 years old, Kano founded his own school at Eishoji Temple in Tokyo. He named it "Kodokan," meaning "the place for studying the way." The first dojo was only 12 tatami mats (about 180 square feet), and Kano began with just nine students.

But Kano's ambition was not merely to teach another style of jujitsu. He wanted to create something new—a system that preserved the best techniques of the old schools while removing dangerous elements, adding scientific principles, and incorporating moral and educational values.

The Principles of Judo

Kano articulated his vision through two core principles:

Seiryoku Zenyo (Maximum Efficiency)

The principle of maximum efficiency with minimum effort. Kano observed that smaller, weaker individuals could defeat larger opponents by using technique and timing rather than strength. This wasn't just about fighting—Kano saw it as a universal principle applicable to all aspects of life.

Jita Kyoei (Mutual Welfare and Benefit)

The principle of mutual benefit and welfare. Judo practitioners train together, helping each other improve. When you throw your partner, you help them practice ukemi; when they throw you, they help you learn. This cooperation extends beyond the dojo into society at large.

"Judo is the way to the most effective use of both physical and spiritual strength."

— Jigoro Kano

Proving Judo's Effectiveness

In 1886, the Tokyo Metropolitan Police organized a tournament to determine which martial art would be taught to officers. The match pitted Kano's Kodokan against the established Yoshin-ryu school. The result was decisive: Kodokan judoka won 13 out of 15 matches, with two draws. This victory established Judo's reputation and led to its adoption by police and military institutions throughout Japan.

Educator and Reformer

Kano was not only a martial artist but also a prominent educator. He served as principal of the Tokyo Higher Normal School (now Tsukuba University) and helped reform Japan's educational system. He introduced physical education into schools, believing that physical and mental development were inseparable.

He also worked tirelessly to bring Judo to the world. Kano was the first Asian member of the International Olympic Committee and campaigned for decades to have Judo included in the Olympic Games—a dream realized in 1964, 26 years after his death.

The Belt System

Kano introduced the dan/kyu ranking system that is now used in many martial arts. He was the first to use colored belts to distinguish rank, initially just white and black, later expanding to include the colored kyu grades. This innovation made it easy to identify experience levels and created a clear path of progression for students.

Legacy

Jigoro Kano passed away on May 4, 1938, while returning from an IOC meeting in Cairo. He died aboard a ship, reportedly of pneumonia. He was 77 years old.

Today, Judo is practiced by millions worldwide and remains an Olympic sport. The Kodokan still operates in Tokyo, teaching the techniques and principles that Kano developed over 140 years ago. But perhaps his greatest legacy is the philosophy he instilled in Judo—that the purpose of training is not just to become a better fighter, but to become a better human being.

"Before and after practicing Judo or engaging in a match, opponents bow to each other. Bowing is an expression of gratitude and respect. In fact, you are expressing gratitude for this opportunity to train together."

— Jigoro Kano

Conclusion

Understanding Kano's story helps us appreciate what we practice. Every time we bow onto the mat, every time we help a partner up after a throw, every time we train with maximum effort and minimum ego, we are continuing a tradition that began with a small, determined young man who refused to be defined by his physical limitations. Kano showed that the gentle way is not weakness—it is wisdom.
