The grading system of Hyakusenkan Karate is uniquely distinctive, setting it apart from many other common Karate systems. It consists of 5 colored belts (kyuu) and 10 black belts (dan). Under normal circumstances, practitioners of Hyakusenkan Karate can only reach the first-degree black belt (Shodan). However, to attain the second to fifth-degree black belts, one must demonstrate significant dedication through training, competition, teaching, research, and the development of the Karate movement. Degrees from the sixth dan and higher are awarded through a special examination board.
Another unique aspect of Hyakusenkan's grading system is the absence of specific time requirements to achieve colored belts, unlike most traditional Karate schools. Students are allowed to take their grading tests only when their Sensei evaluates that they are ready to pass the current Kyu level.
Moreover, the existence of the gray belt further enhances the distinctiveness of the Hyakusenkan grading system. The gray belt serves as a recognition for individuals with a certain level of skill in other martial arts or Karate styles, who have not yet reached the certification level of Hyakusenkan, but can contribute as assistant instructors. The gray belt has 5 stripes, corresponding to the 5 Kyu levels, and serves as a stepping stone for advancing to higher ranks within the system.
At the 5th and 6th Dan levels, practitioners earn the esteemed title of Renshi. Those reaching 7th and 8th Dan are honored as Kyoshi, while the 9th Dan is recognized with the title Hanshi.
