Jigoro Kano is the founder of judo as we know it today. He excelled in schoolwork but had an inferiority complex about his small physique. So he became an apprentice of Yanosuke Fukuda, a master of the Tenjin Shin'yo school of jujitsu, when he was 17 and worked to become stronger. In 1882, when he was just 21 years old, he took the best things about each jujitsu style and created a single new school. This was the birth of modern judo. The Kodokan Judo was recognized in a few years to be excellent since its students overwhelmed the jujitsu athletes at the Police Bujitsu Contest.
The categorization of Kodokan Judo was completed about 1887. The Kodokan had three broad aims: physical education, contest proficiency and mental training. In 1899, Kano was asked to chair a committee of the Dai Nippon Butoku Kai to draw up the first formal set of contest rules for jujutsu. These rules were intended to cover contests between different various traditional schools of jujutsu as well as practitioners of Kodokan judo. In 1900, these rules were adopted by the Kodokan, and about the same time he travelled to Europe and America to promote his martial art further. The Kadokan became a foundation in 1909 and in 1922 brought the foundation of the Kodokan Cultural Judo Society. The International Judo Federation was founded in 1952.
Proceeding with the organization of the Kodokan and enacting the regulations of Judo, Kano became the first Asian member of the International Olympic Committee in 1909 and worked for the spread of Judo world-wide. The first time judo was seen in the Olympic Games was in an informal demonstration hosted by Kano at the 1932 Games, in Los Angeles, United States. However, Kano was ambivalent about judo's potential inclusion as an Olympic sport. Nevertheless, judo became an Olympic sport for men in the 1964 Games in Tokyo. The women's event was introduced at the Olympics in 1988 as a demonstration event, and an official medal event in 1992.
