How does a karateka get the formal rank?
Karate
Kata (型:かた) means literally "shape" or "model." Kata is a formalized sequence of movements which represent various offensive and defensive postures. These postures are based on idealized combat applications. The applications applied in a demonstration with real opponents is referred to as a Bunkai. The Bunkai shows how every stance and movement is used. Bunkai is a useful tool to understand a kata. To attain a formal rank the karateka must demonstrate competent performance of specific required kata for that level. The Japanese terminology for grades or ranks is commonly used. Requirements for examinations vary among schools.
