In koryū, hierarchies and grades are structured differently from modern martial arts. They are not based on colored belts, but rather on licenses or certificates that indicate the practitioner's level of understanding and mastery. These licenses may include terms such as 'Shoden' (beginner), 'Chūden' (intermediate), 'Okuden' (advanced), and 'Menkyo Kaiden' (full system streaming). The system reflects not only technical skill, but also commitment, understanding, and ability to teach ryū traditions.
