Rank in judo

{{nihongo|Practitioners of Judo|柔道家|Jūdōka}} are ranked according to their skill and knowledge, and, for high ranking dan grades, their contribution to the art. Their rank is indicated by the colour of belt that they wear. There are two broad categories of rank: those who have attained a level of competency at which they are considered worthy of a {{nihongo|black belt|黒帯|kuro obi}} and who hold {{Nihongo|dan|段}} grades and those who are yet to attain that level and who hold {{Nihongo|kyū|級}} grades. Those who hold dan grades are collectively termed {{nihongo|Yūdansha|有段者|}} (literally "person who has dan") and those with kyū grades are {{nihongo||無段者|Mudansha}}, literally "person without dan". High grade "Judoka" 5th dan to 10th dan are Kōdan-sha (高段者) literally "person of high rank" and the "esteemed" grades of 6th, 7th, and 8th dan have alternating red and white panel belts (紅白帯) Kōhaku-obi, and for the "venerable" Kōdan-sha (高段者) "high ranking" grades of 9th and 10th dan, their belts are solid and bright red.

This ranking system was introduced by Kanō Jigorō, the founder of judo, in 1883. However, the current system is not the original one, but based on Kanō's last system introduced between 1926 and 1931, with some modification shortly after Kanō's death in 1938. The first dan grades were awarded to his students Saigō Shirō and Tomita Tsunejirō. Since then it has been widely adopted by other modern martial arts.{{Cite web

In the current system as in use in Japan, there are six student grades ranked in descending numerical order. Beginners were given the rank of {{nihongo|sixth kyū|六級|rokkyū}} and wore a light blue belt. Once they had passed an elementary level of instruction, they were promoted to {{nihongo|fifth kyū|五級|gokyū}}, when they would adopt the white belt. This they wore through {{nihongo|fourth kyū|四級|yonkyū}}. The remaining three grades ,{{nihongo|third kyū|三級|sankyū}}, {{nihongo|second kyū|二級|nikyū}} and {{nihongo|first kyū|一級|ikkyū}} were all indicated with brown belts (for seniors) or with purple belts (for juniors).

1st kyū is the last kyū rank before promotion to first degree black belt (shodan). There are (in practice) 10 dan ranks, which are ranked in ascending numerical order.{{cite journal|title=Judo: 20 questions responses according to the studies and documents published by the Judo review of the Kodokan in Tokyo|pages=3/2573|year=1963|publisher=Kōdōkan}}

The ninth (kudan) and tenth degree black belt (jūdan) and, theoretically, those higher, have no formal requirements. Only 15 individuals have been promoted to the rank of Kōdōkan 10th dan. On January 6, 2006, three individuals were promoted to this rank simultaneously: Daigo Toshirō, Ichirō Abe, and Ōsawa Yoshimi. This is the most ever at the same time, and the first in 22 years. No one has ever been promoted to a rank higher than 10th dan, but in theory the judo rank system is not limited to 10 degrees of black belt. As an educator by profession, Kanō believed that there should be no end to an individual's learning, and therefore no limit to the number of dan ranks. The English language edition (1955) of Illustrated Kodokan Judo, edited by the Kōdōkan, says:

{{blockquote|There is no limit ... on the grade one can receive. Therefore if one does reach a stage above 10th dan ... there is no reason why he should not be promoted to 11th dan.}}

This statement was later clarified, however. Essentially, the dan-rank system was capped at 10 after the death of Kanō. In that respect, in the November 1963 issue of Jūdō, the Kōdōkan's official magazine, the Kōdōkan responding to the question "Do the 11th and 12th Dan really exist?" *clarifies that the hierarchy now stops at 10 and that the Kōdōkan does not envisage any nominations to these grades.

There have only been fifteen 10th dan promotions awarded by the Kōdōkan itself in the history of Judo.

Although dan ranks tend to be consistent between national organizations there is more variation in the kyū grades, with some countries having more kyū grades. Although initially kyū grade belt colours were uniformly white, today a variety of colours are used. The first black belts to denote a dan rank in the 1880s{{clarify|date=May 2022}}. Initially the wide obi was used; as practitioners trained in kimono, only white and black obi were used. It was not until the early 1900s, after the introduction of the judogi, that an expanded colored belt system of awarding rank was created.

Examination requirements vary depending on country, age group and of course the grade being attempted. The examination itself may include competition and kata. The kyū ranks are normally awarded by local instructors (sensei), but dan ranks are usually awarded only after an exam supervised by independent judges from a national judo association. For a rank to be recognized, it must be registered with the national judo organization or the Kōdōkan.

The appearance of the belts makes the judoka's level visible. Upon successful graduation, you are entitled to a new degree. The kyu degrees are counted down from 6 to 1. The dan degrees are counted up from 1.

For dan ranks, the first five are colored black, 6th, 7th and 8th dan have alternating red and white panels (紅白帯) Kōhaku-obi, commonly known as the "Coral belt," named after the coral snake, and for 9th, 10th dan and above, the belts are solid red. In Europe, according to the ‘IJF’, there is a difference between each grade belts' marking by the difference in length of the alternating white-red coloured blocks of the coral belt, as in “the more blocks in your belt, the higher the grade,” (e.g. for 6th dan, 20cm white-red block, 7th dan: 15cm white-red block, and 8th dan: 10cm white-red block – (in Japan, this difference in block size doesn't seem to apply).{{cite web|url=http://r25.jp/magazine/ranking_review/10002000/1112008051512.html|script-title=ja:柔道帯の最高位は、何と紅!?

However, since the highest dan rank reached in judo for a living person, or conferred posthumously remains 10th dan, any judo dan rank higher than 10th dan is now considered as a merely historical theoretical option. Some time after the death of Kanō, the promotion system essentially became capped at 10th dan.{{cite book|last=Dominy|first=Eric|title=Judo|year=1958|publisher=NEL four square}} Furthermore, holders of a dan rank above godan (5th dan) will often wear a plain black belt during regular training practice, and outside any ceremonial duties. Compared to both Brazilian and Gracie Jiu-Jitsu, dan ranks are not signified by coral belts with black and red panels.

The Kyu belt system can contain the colors white, red, yellow, orange, green, blue, purple, and brown for both senior and junior practitioners. In some countries junior practitioners have an extra system in place to show the progress in between two kyū grades. The sub rank can be symbolized by a small piece of fabric on the end of the belt. The piece added to the belt can never be of a lower or the same color as the belt worn by the judoka, so an orange belt cannot have a yellow piece, but it can have green, blue or brown.

In Australia belt rankings for Seniors are, in ascending order: white, yellow, orange, green, blue, brown and finally black. Belt rankings for Juniors follow the same ranks and colours (up to and including brown), but have either 1, 2 or 3 white bars (depending upon age) at each end of the belt, as follows:

• If the judoka is aged up to 10 (Mon), there are to be 3 white bars.
• Between 10 and 13 (Yonen), there are 2 bars.
• Finally, for 13 to 16 years of age (Shonen), there is a single bar.{{cite web

Brazilian belt rankings are normally white, grey, blue, yellow, orange, green, purple, brown.{{cite web |title=CBJ (Confederação Brasileira de Judô) - Regulamento Nacional para Exame e Outorga de Faixas de Graus - 2023 |url=https://cbj.com.br/public/uploads/regulamentos_esportivos/arquivo_cbj_180223310123.pdf}}{{cite web |title=FJERJ (Judo Federation of Rio de Janeiro) - Judo Graduation |url=http://www.judorio.org.br/graduacao_do_judo.html |archive-url=https://web.archive.org/web/20120324183505/http://www.judorio.org.br/graduacao_do_judo.html |archive-date=2012-03-24}} As in some European countries, young judoka in Brazil have an extra system in place to show the progress in between two kyū grades. The sub rank exists between white and orange belts and is symbolized by the ends of the current belt being the color of the next rank.

Judoka above 16 years old can skip some of the basic kyu, until the 5th (considered "basic" kyu by the Brazilian Judo Confederation). It is usual for adults to progress directly from white (12th kyu) to blue belt (8th kyu), not ever taking the grey belt. It is also usual for adults to skip the sub ranks, meaning that they will progress from blue to yellow belt (6th kyu) and then to orange belt (4th kyu).{{cite web |title=CNN Brasil - Faixas de judô: conheça a ordem correta e o significado das cores |url=https://www.cnnbrasil.com.br/esportes/outros-esportes/faixas-do-judo/}}

In Canada belt rankings for Seniors are, in ascending order: white, yellow, orange, green, blue and brown. Belt rankings for Juniors use, white, white-yellow, yellow, yellow-orange, orange, orange-green, green, green-blue, blue, blue-brown, and brown.{{cite web |title=NATIONAL KYU GRADING SYLLABUS |url=https://judocanada.org/wp-content/uploads/2021/08/2021-06-25-National-Kyu-Grading-Syllabus-EN.pdf }}

There are 6 kyu degrees. Seniors wear full-colored belts while children and youth (ages 6–14) also wear half-colored belts.

In Finland, junior sub ranks below a certain age are denoted by one to three red stripes on both ends of the belt. They are also used to signify that joint locks, chokes or strangles may not be performed upon the wearer as those are not taught nor applied to juniors below the age of 15 due to safety reasons.

Minimum age requirement for first Dan is 16 years (exception 15 years with special preconditions).

In Germany the following belt colors exist:

In Ireland the senior belt system is white, yellow, orange, green, blue, brown and black. A practitioner must be at least sixteen before being eligible to grade for blackbelt. For white, yellow, orange and green belt gradings are held in the practitioners club and are based on demonstration of a syllabus and kata. For promotion to blue and brown the judoka must compete at a national grading against players of their own rank and win at least two fights by ippon or wazari. To achieve black belt a judoka must earn 100 points i.e. 10 points for every ippon or waza-ari victory against a brown belt.{{Cite web |title=GRADING INFORMATION 2022 |url=https://irishjudoassociation.ie/wp-content/uploads/2022/05/IJA-Grading-Syllabus-V7-2022-1.pdf}}

In Israel the following belt colors exist:

In Japan, the use of belt colors is related to the age of the student. Some clubs will only have black and white, others will include a brown belt for advanced kyū grades and at the elementary school level it is common to see a green belt for intermediate levels.

In the United Kingdom a red belt is used between the white and yellow belts to signify full membership of the home Country's national Judo governing body i.e. JudoScotland, Welsh Judo, Northern Ireland Judo and in England, British Judo (BJA). A practitioner must be at least fifteen before being eligible to grade for Shodan black belt 1st dan. The British Judo Association Kyu Grade system is as follows:

In the United States, only seniors (usually age 16 and older) are allowed to earn the dan levels, signified by wearing the same belts. The United States Judo Federation (USJF) and United States Judo Association (USJA) both recognize the same dan grades. Advanced kyū levels can be earned by both seniors and juniors (children under the age of around 16) and are signified by wearing belts of various colors other than black, coral, or red. The order of belt colors can vary from dōjō to dōjō, depending on the dōjō's organizational affiliation.

For seniors, both the USJF{{cite web| title = United States Judo Federation Rank Requirements| url = http://www.usjf.com/public/rank_requirement.pdf}} and the USJA specify six kyū ranks, as listed in the table. In a similar manner to Brazilian Jiu Jitsu, The USJA requires "Beginners" (not yet qualified as a kyū) to wear a beginning white belt until they test for yellow belt. The USJA also recommends that a patch is worn, specifying the practitioner's level for both kyū and dan levels.

The USJF Junior ranking system specifies ranks up to 11th kyū (jūichikyū). The USJA Junior ranking system specifies twelve levels of kyū rank, beginning with "Junior 1st Degree" (equivalent to jūnikyū, or 12th kyū) and ending with "Junior 12th Degree" (equivalent to ikkyū). As with the senior practitioners, the USJA recommends that juniors wear a patch specifying their rank. When a USJA Junior reaches age 16 or 17, their conversion to Senior rank is:{{cite web
