Martial Arts Dan and Kyu Ranks - JSON

The dan and kyu ranking system in martial arts was established by Jigoro Kano in 1883 for Kodokan Judo. Kyu ranks indicate progression from beginner to advanced levels, while dan ranks represent achievement as a black belt holder. Adopted by major martial arts including judo, kendo, and karate, ranks are visually distinguished by belt colors or badges. Achieving shodan (first dan) earns the black belt, and higher dan ranks evaluate not only technique but also teaching ability and character.
