Japanese name
Hiragana きゅう
Revised Hepburn kyū

Kyū (級) is a Japanese term used in modern martial arts as well as in tea ceremony, flower arranging, go, shogi, academic tests and other similar activities to designate various grades, levels or degrees of proficiency or experience. In China, kyū (級) is called "ji", and it is used for academic tests. In Korea, the term geup (급) is used (also transliterated as gup or kup). In Vietnamese martial arts, it is known as cấp (khớp).


In 1883, Kanō Jigorō, the founder of Judo, established the system of Dan ranking to measure the Judo practitioners' ability. This system was derived from the Dan ranking system of Go, the ancient board game. Some organizations of academic tests started using the Kyū ranking system to measure candidates' ability.

Similarly, the Tokyo Metropolitan Police Department started a ranking system using Kyū to measure the police officers' ability in Kendo. Grades were from 8th to 1st.

In the 1890s, the Greater Japan Martial Virtue Society introduced the dan and kyū ranking system to other martial arts in Japan.

Martial arts usage

The certificate of 8th kyū in karate.

In modern Japanese martial arts, kyū-level practitioners hold the ranks below dan or black belt. The kyū ranking system varies from art to art and school to school. In some arts, all the kyū-level practitioners wear white belts while in others different coloured belts, tags or stripes are used; in kendo for example the belt system is not used. Although some aikido schools do use a coloured belt system the norm is for kyū grades to wear a white belt, and for dan grades to wear a black belt. Kyū-level practitioners are often called mudansha (無段者), "ones without dan" and are considered as initiates rather than students. When practitioners have reached the ranking of first degree black belt, they become shodansha (初段者). The holder of a black belt of any degree is a yūdansha (有段者), "one with dan".

Academic tests usage

The certificate of Pre 2nd kyū Japanese Kanji examination.

Martial arts' organizations are not the only ones who use such as system. Some academic and professional organizations also use kyū and dan as measures of a person's ability. For instance, the Japan Kanji Aptitude Test which tests a person's ability to correctly read, write, and use kanji, is graded using kyū.

List of Kyū ranks

Some martial arts refer to the kyū ranks entirely in Japanese. Kyū ranks progress using a descending order system, so 1st kyū is the highest. For example, the first kyū outranks the 2nd kyū. The Dan ranking system starts after 1st kyū. Essentially, the kyū is the number of steps before reaching mastery whereas the dan gives steps into mastery.

Pre-1st kyū and pre-2nd kyū are used in examinations of languages, because it is often hard to pass the examinations at 1st and 2nd kyū.

Grade Pronunciation Japanese
1st (Highest) Ikkyū 1級 / 一級
Pre 1st Jun-Ikkyū 準1級 / 準一級
2nd Nikyū 2級 / 二級
Pre 2nd Jun-Nikyū 準2級 / 準二級
3rd Sankyū 3級 / 三級
4th Yonkyū 4級 / 四級
5th Gokyū 5級 / 五級
6th Rokkyū 6級 / 六級
7th Nanakyū 7級 / 七級
8th Hakkyū / Hachikyu 8級 / 八級
9th Kyūkyū 9級 / 九級
10th Jikkyū / Jukkyū 10級 / 十級
Non-Grade Mukyū 無級

The lowest kyū is sometimes called "Mukyū" (無級) which means "Non-Grade" in English. The lowest kyū depends on organizations. For instance, the United States Judo Federation has 12th kyū as the lowest grade for junior class, and 7th kyū as the lowest for adult class.

In Japan, the difficulty is classified into three categories as in the following list.

Grade Pronunciation Japanese
Highest Jōkyū 上級
Middle Chūkyū 中級
Beginning Shokyū 初級

Kyū ranks in China

The grading system of Kyū is imported to China too. Kyū (級) in China is called "ji" (same character different pronunciation), and 1st kyu is the lowest as same as descending order. For example, the Chinese language test certified HSK uses 6th ji as the highest grade.

Coloured belts

Karateka wearing different coloured belts

In some styles, students wear white belts until they receive their first dan rank or black belt, while in others a range of colors are used for different kyū grades. The wearing of coloured belts is often associated with kyū ranks, particularly in modern martial arts such as karate and judo (where the practice originated). However, there is no standard association of belt colours with particular ranks and different schools and organizations assign colours independently; see Rank in Judo for examples of variation within an art. However, white is often the lowest ranked belt and brown is the highest kyū rank, and it is common to see the darker colors associated with the higher ranks, i.e. the closest to black belt.

The system of using different colored belts to mark rank is not universally accepted in the martial arts. Supporters of the belt colors point out their use as a simple visual key for experience, such as in matching opponents for sparring, allowing opponents to somewhat accurately judge each other's skill, and to split them for competitions. Those who oppose the use of coloured belts are also often concerned that students will worry too much about relative rank, and become arrogant with trivial promotions and differences, while supporters feel that by providing small signs of success and recognition, students are more confident, and their training is more structured, and that the ranking system encourages higher ranked students to assist lower ranked ones, and lower ranked students to respect their seniors.
