The founder of Judo Jigoro Kano was born in 1860, he graduated with a degree in literature from Tokyo Imperial University in 1881 and took a further degree in philosophy the following year. Apart from being the founder of judo, Kano was a leading educationalist and a prominent figure in the Japanese Olympic movement.

When Kano began his study of ju-jutsu as a young man, the ju-jutsu masters of the martial arts were struggling to earn a living. Although they were willing to teach the skills handed down to them over many generations, there was little interest among people of the succeeding generation, additionally the demise of the samurai (warrior) class had reduced the need for instruction.

At the age of 18 Kano studied the ju-jutsu of the Tenshin Shinyo Ryu under Fukudo and Iso, both instructors at the prestigious Komu Sho. Following the death of Fukuda, Kano remained briefly with master Iso before finishing his pupillage with master Ilkubo.

By 1883, Kano had clarified his analysis of ju-jutsu and related methods to the point at which he felt able to instruct the public through a school of his own. To that end he borrowed a small room at Eishoji temple and opened the first Kodokan for the study of Kano judo.

A number of machi dojo (backstreet gyms) decided that the Kodokan was conceited and ought to be put in its place. They visited its premises and caused damage so that if honor were to be satisfied a challenge match would have to be arranged. At such matches the Kodokan was represented by Sakujiro Yokoyama, the outstanding player of his day, and the result was invariably a win for Kano judo.

Judo entered many countries from 1902 to the 1930's. In the United States judo gained an early foothold because of the interest shown by President Theodore Roosevelt. As an expression of goodwill Kano sent Yoshiaki Yamashita, a high ranking member of the Kodokan, to America in 1902 to be his personal instructor. Roosevelt trained regularly , if clumsily and in due course a room was set aside at the White House for judo purposes. It was thirty-odd years, however, before an American reached dan grade in the USA itself. Clubs were set up in Seattle in 1903 and Los Angeles in 1915. Brisbane Judo Club was the first founded in Australia in 1928 by DR A J Ross, a Kodokan dan grade. Judo later reached New Zealand via Australia in 1948 when G Grundy, a 2nd Dan from the Budokwai, opened a club in Auckland.

The most successful "newcomer" so to speak is the USSR. Strictly speaking a form of judo has been practiced in the Soviet Union since about 1930. The Russians practice a wrestling system called Sambo. This is a synthesis of many different wrestling systems, however because of the absence of international competition outside of the USSR, the Russians turned their attention to judo. In 1962 a Soviet judo team comprising Sambo men in judo suits collected five medals at the European Judo Championships. Sambo is a close cousin of judo, but it lacks the same conceptual framework. It can be seen as an implied compliment that the Russians have stepped up considerably the emphasis on judo during recent years
