Traditional koryu bujutsu, the classical martial arts practiced before the end of the samurai era in 1868, never used a kyu/dan belt system. Instead, these systems relied on menkyo (“teaching licenses”), similar to collegiate-level degrees.
Where the Belt System Actually Came From
Today’s kyu/dan system originated with Kano Jigoro, the founder of judo, following the abolition of the samurai class in the late 1800s. Kano had a merchant background, and his ranking system reflected a new, more accessible era for martial arts training.
Why So Many Levels?
- Kyu/dan system can include as many as ten kyu and ten dan levels.
- Menkyo’s licensing model has only three to five steps, similar to a bachelor's, master's, and doctoral degree.
As martial arts spread beyond a single ryu and single instructors, menkyo licensing didn’t provide a way to track and communicate incremental progress across a much wider, more varied group of students.
Why Organizations Rely on Kyu/Dan
Martial arts industry associations adopted a consistent, well-understood ranking structure across a broad and varied membership by moving from menkyo to kyu/dan.
An Important Distinction
A martial arts industry association can certify rank within its own organization, but not within a specific ryu. That authority belongs solely to the current head of that tradition. What an association can offer instead is a documented, standardized rank based on a member's training, technical skill, and knowledge of their specific art.
Rank as a Practical Tool
Belt systems solved a coordination problem that emerged once martial arts moved beyond a single teacher and a single system. Today, they're used to recognize rank across martial arts, communicating at a glance roughly what a student has learned and how long they've trained.
