Kano Jigoro is the creator of judo, the first Japanese martial art to gain widespread international recognition, and the first to be recognized as an official Olympic sport.

Educators of the new innovations presented to Jigoro Kano should be used on white and black belts and be introduced to the dans to show the relative seniority of the average sportsman given a martial art. Kano also introduces some well-known mottos such as: "Maximum efficiency with minimum improvement" and "Shared wealth and benefit".

He was born on October 28, 1860 in Mikage, in the Kobe region. In 1871, Jigoro's family moved to Tokyo. As a child, Jigoro was a weak and sickly, the diseases followed one after another. Despite the doctors' advice, Kano decided to do something to improve his health and at the same time learn to defend himself. At the age of 18, he began studying at the Fukuda Hachinosuke School in Tenjin Shin'yo-ryu Jujutsu. Tenjin Shin'yo-ryu is a soft martial art that emphasizes more harmony than fighting, but at the same time includes striking techniques and throwing techniques. In 1882 is when he created the Kodokan Judo.
