The Color Belt Ranking System

The old Okinawan Karateka, it is told, all wore white belts. Their peasant clothing was simply cotton pants and jacket, tied with a white cloth obi (belt). As they progressed in their instruction they would continue to wear this simple uniform. It became the custom for them to wash their Gi's, but never the obi. So, in the beginning, the belts were white

After the students had rolled and wrestled on the grass (being poor men, they practiced outside in the fields) for a while the belts would become stained with chlorophyl, turning them green.

And yet after a while more, with the grass now worn away beneath them, the Karateka would practice on bare earth, often plain mud. Belts became brown.

It was not until the student had reached a high degree of proficiency in the art of Karate, when serious training was done with nothing held back, that the grass and mud-stained brown belts would be darkened with blood, turning them black.


The ranking system in USA GOJU tells, by a glance at the obi (belt), the general level of competence a student has achieved in the art. The beginning levels are called "Kyu" levels (kyu being a Japanese word for "boy"). These progress from high numbers to low numbers, 10th kyu to 1st kyu. Once the practitioner reaches black belt level the training levels are called "Dan" (a Japanese word for "man"). These rankings progress from low numbers to high numbers, 1st Dan to 10th Dan.


The Kyu levels are:


  • 10th Kyu - A raw beginner, training in "civvies", that is, sweats or gym shorts. No Karate uniform yet.


  • 9th Kyu - Beginner. Plain black Gi with plain white obi.


  • 8th Kyu - Beginner. Black Gi and white obi with a single rank stripe* near the end.


  • 7th Kyu - Beginner. Black Gi and white obi with two rank stripes near the end.


  • 6th Kyu - Intermediate. Black Gi and green obi (with possibly one rank stripe).


  • 5th Kyu - Intermediate. Black Gi and green obi with two rank stripes near the end.


  • 4th Kyu - Intermediate. Black Gi and purple** obi.


  • 3rd Kyu -   Advanced. Black Gi and brown obi (possibly with a single rank stripe).


  • 2nd Kyu - Advanced. Black Gi and brown obi with two rank stripes.


  • 1st Kyu - Advanced. Black Gi and brown obi with three rank stripes.


* The rank stripes are traditionally of the color of the next higher belt, ie: white obi with green stripes, green obi with purple stripes, brown obi with black stripes. It is not uncommon, though, for a Sensei to use the more readily available black tape for all rank stripes.

** The use of the purple obi seems to be a more recent addition to the style. It is reported that in times past the 4th Kyu would wear a green obi with three rank stripes.

Color belt ranking varies widely from Master to Master and from style to style. Some use different colors (e.g.: yellow, gold, orange or blue) rather than rank stripes to differentiate between Kyu levels. The general rule is, "the darker the color, the higher the rank."

The Dan levels are:

  • 1st Dan (Shodan) -    Black obi (sometimes worn with a single red rank stripe).


  • 2nd Dan (Nidan) - Black obi with two red rank stripes.


  • 3rd Dan (Sandan) - Black obi with three red rank stripes.


  • 4th Dan (Yodan) - Obi is half white, half red, the colors running lengthwise*. The white edge is worn above the red.


  • 5th Dan (Godan) - Obi is half red, half white. Same as 4th Dan except that the red edge is worn above the white.


  • 6th Dan (Rokudan) - Black obi with red center stripe running lengthwise.


  • 7th Dan (Nanadan -or- Sichidan) - Black obi with red center stripe running lengthwise.


  • 8th Dan (Hachidan) - Black obi with red center stripe running lengthwise.


  • 9th Dan (Kudan) - Master of the style. Red obi.


  • 10th Dan (Judan) - Master of the style. Red obi.


The upper levels of the style, Kyoshi (6th, 7th, and 8th Dan) and Shihan (9th and 10th Dan), do not require exact differentiation in obi markings. They will invariably know each other and each other's level, and further distinction is not necessary.

* If a practitioner of Renshi rank (4th or 5th Dan) cannot find such an obi available he or she will often wear a black obi with additional red rank stripes.

It is sometimes the case that someone who has achieved an upper Dan training level will wear a simple black obi for non-formal training sessions.
