Who picks who gets " judan " in the kyu - dan Judo ranking system ?
Half - grades for juniors were introduced in 2010 and are represented by belts that combine the colours of the previous grade and the next grade ( a white and yellow belt , for example , represents a half - grade between " rokkyū " and " gokyū " , which the grading syllabus calls " 6th + " kyū "" ) .
