In Japanese, the term for karate belt is "obi". The kyū ranking system is used in modern Japanese martial arts, including karate, to indicate the rank of practitioners below dan or black belt. The kyū ranking system varies from art to art and school to school, but in karate, the following colors are commonly used for different kyū grades:
- White Belt (Mukyu): Beginner belt that indicates no progress.
- Orange Belt (X Kyu): First belt that a student receives following an examination, indicating initial progress in studying karate.
- Green Belt (Yonkyu): Fourth kyu, indicating intermediate progress.
- Blue Belt (Gokyu): Fifth kyu, indicating intermediate progress.
- Purple Belt (Sankyu): Third kyu, indicating advanced progress.
Its important to note that the belt colors and their meanings may vary depending on the style of karate and the specific dojo.
