The Surprising History Behind Martial Arts Belt Systems

Most students assume the belt system stretches back centuries. However, it’s fairly new. 

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.
