Japanese martial arts

 In Japanese martial arts the further subdivisions of black belt ranks may be linked to dan grades and indicated by 'stripes' on the belt. Yūdansha (roughly translating from Japanese to "person who holds a dan grade") is often used to describe those who hold a black belt rank. While the belt remains black, stripes or other insignia may be added to denote seniority, in some arts, very senior grades will wear differently colored belts. In judo and some forms of karate, a sixth dan will wear a red and white belt. The red and white belt is often reserved only for ceremonial occasions, and a regular black belt is still worn during training. At 9th or 10th dan some schools award red. In some schools ofJujutsu, the Shihan rank and higher wear purple belts. These other colors are often still referred to collectively as 'black belts'.^[4][6]
