A judo red belt is worn by 9th and 10th dan, the highest grades that exist. Just below, the red and white belt is for 6th, 7th and 8th dan. Nobody earns these belts in competition. They recognize decades of practice, teaching and service to judo.
Where the judo red belt sits among the grades
The system starts at white, runs through the kyu colors, then black. Past 5th dan, the color changes again:
| Grade | Belt |
|---|---|
| 1st to 5th dan | Black |
| 6th to 8th dan | Red and white (alternating panels) |
| 9th and 10th dan | Red |
Wearing the red and white belt is optional. Many 6th or 7th dans keep a plain black belt for training, for simplicity or modesty, and save the other for ceremonies, seminars and gradings. Both habits show up in every dojo.
For how the dan grades work, from shodan to judan, see our page on judo dan grades.
How do you get a red and white belt?
Above black belt, promotions are handled by the national federation or, for its own grades, by the Kodokan. The higher you go, the longer the conditions. High dan grades usually require a minimum age, often well into middle age, and many years in the previous grade. Some federations offer adjusted routes for coaches or former elite competitors. The exact numbers change by country and by season, so only your federation's current rules count.
At this level, competition no longer matters. Panels look at a technical demonstration, the ability to explain judo and, above all, a career: students trained, roles in a club or region, years of refereeing or coach education. From here on, recognition of what someone has given to judo outweighs any test.
The red belt, the top of judo
9th and 10th dan are exceptional. The Kodokan in Tokyo has awarded 10th dan to only a handful of judoka since it was founded. In most countries, 9th dans can be counted on two hands.
These grades honor people who shaped judo in their country: pioneers, great teachers, technical leaders. The Kodokan, founded by Jigoro Kano, remains the historical reference for the whole system.
When kids ask how to get a red belt, the answer is simple: you do not aim for it. Nobody starts judo with 9th dan as a goal. The people who get there just kept training and teaching for fifty years, long after their old training partners had stopped.
High grades in club life
Few clubs have a 6th dan on the mat. When they do, that person rarely takes center stage. You find them at the edge of the mat during gradings, or in a corner of the dojo with two brown belts working on their kata. Their job is to correct details nobody else sees: a foot in the wrong place, a pulling hand that fires too early, an uke who anticipates the fall.
High grades also sit on grading panels and commissions. They pass the shared standard on to new examiners, so that a 1st dan earned in one city is worth the same as one earned elsewhere.
They are often the memory of local judo too. Many of them remember the first dojos in their region, the early Japanese teachers who came to coach abroad, and every rule change since. Take the time to listen. The history of judo reads differently when you hear it from someone who lived part of it.
Not to be confused with the competition red belt
At some events, especially for kids, one fighter wears a red belt over their own and the other a white one. It only helps the referee and the crowd tell them apart. At senior international level, the judogi color does that job instead: see our page on blue and white judogi rules.
So a parent whose child comes home from a tournament wearing a red belt should not be surprised. Nobody skipped fifteen grades.
And in Brazilian jiu-jitsu?
BJJ also has red belts, with similar logic but different steps: red and black, then red and white, then solid red for the highest black belt degrees. Timelines and conditions depend on the BJJ federation. Our guide to BJJ belts explains that progression.
What these belts say about judo
A red and white teacher who steps onto the mat is not there to win. They fix a foot position, show an off-balance, remind people what the bow means. The grade says they have spent their life doing exactly that.
For a young judoka, meeting a high grade at a seminar is a chance. Ask a precise technical question rather than one about their rank. You will learn more in ten minutes than in a month of reading. To see these belts in the full progression, our guide to judo belt colors in order covers everything from white to red.
