Our Belts and their Requirements

Requirements for Promotion


The Kobujutsu Kai sets the standards for the material taught by its various Dojo. In an effort to establish a little uniformity across the Association the following Membership and Time guidelines have been established.

Children and today's society represent a challenge for our profession. So, in order to increase our appeal (and help with student retention while undercutting the diploma mills), we have instituted a system designed to excite them. These Ranks are not Kyu or Dan Ranks. They are simply colored belts designating a child's progress at the Dojo (training hall). Once a child reaches the age of fifteen, they may start fulfilling the Rank Requirements for Kyu grades leading up to Shodan.


These Ranks are suggestions. The time limits in the "Black" Belts are arbitrary and only a suggestion. It is up to the individual Shihans to determine what is best for them.

The Kobujutsu Kai uses colored belts, in this order, for the Kyu grades:



And the Ryukyu system in the Dan ranking:
