waiting period between 1st kyu and 1st dan is typically a 6-12 month. Time between dan gradings increases approximately in yearly increments as the grade progresses. Kyu Grades run from 10th kyu to 1st Kyu and Dan grades from 1st Dan to10th Dan. Although kyu grades are coloured to show progression, all dan grades wear only black belts. Dan gradings are taken under an authorized grading examiner. Senior grades above 5th Dan come specifically under the auspices of the JSKA Chief Instructor and are examined at national/international events (such as National/International Competitions). Depending on the grade being taken a similar format to the kyu grades is required covering all three sections of the training. The karateka must demonstrate a single kata of their choice while the chief examiner will choose another kata from a set list, depending on grade, to be performed. As the grades progress a research paper must be presented and the bunkai (application) of a kata chosen by the examiner, must be shown and explained.
