The creation of the dan/kyu system as it is known today belongs to Jigoro Kano, founder of Judo, who had a dans system in his school divided into five grades. In 1883 he gave the first danes to two of his most outstanding students (Saigo and Tomita) and in 1920 advised to apply this system on karate so it could be accepted as a sport. By 1935 Mikonosuke Kawaishi introduced the colors in the range of Kyu or Mudansha in Paris, these are the most important references for the modern sport.

Meaning and Symbolism of the Degree

“Dan” as a term, dates from a previous era, was used to differentiate the level of the adept in the different stages of progression in the martial arts. The Degree was used to determine the progression of the disciple and could be in three levels: SHODAN, NIDAN and SANDAN (low, medium and high level). On the other hand, a “Kyu” is a student. It comes from the kanji used to represent the word thread. In this case, the thread symbolizes the will, which must be discovered and cultivated so that it does not cut and reach continuity in practice. So, Dan refers to the level to reach and Kyu to the grade achieved by the disciple.
