In the kyu grading system, the first kyu is the highest grade, but in the dan grading system the more advanced the training is, the larger the number of the grade becomes, thus enabling performers to ascend the ladder of grades interminably.
級位制度は一級が最高であるが、段位制度は階段を果てしなく昇れるように修行が進むほどに数字が大きくなるように創設された。
