Black belts include all students who have achieved the Dan ranking. Among them are those who have reached at least 1st Dan but choose not to pursue an instructor qualification, remaining dedicated practitioners without teaching credentials.
They wear the traditional white/red student Gi. However, at official events, black belts are required to wear the winter uniform, which features the black belt badge along with their country’s flag on the chest just like instructors. During the summer season, they wear the summer uniform, identical to that of the instructors (for more details, please refer to the uniform guidelines).
