judogi

The judogi is the heavy cotton uniform worn in judo: a jacket (uwagi), trousers (shitabaki), and belt (obi). Jigoro Kano founded judo at the Kodokan in Tokyo in 1882, adapting techniques from several schools of jujutsu. The garment he standardized drew on the keikogi, a training uniform already in use in martial arts and dance, but Kano made the jacket heavier and the lapels wider to withstand the gripping and throwing that define judo practice. The name is a straightforward Japanese compound: judo (柔道, the gentle way) plus gi (着, garment or wear).

The character 着 (gi, also read chaku) means to wear or to arrive, and appears in dozens of Japanese compound words for clothing. In the context of martial arts, it shortens to gi and attaches to the name of the practice: kendogi for kendo, karategi for karate, aikidogi for aikido. The judogi jacket is cut longer than those of other martial arts, its collar reinforced to resist the grips of throws like seoi-nage (shoulder throw) and osoto-gari (major outer reap). By the 1920s, the Kodokan had published formal specifications for judogi fabric weight and sleeve length.

When judo spread to Europe in the early twentieth century, first to Britain and then France through Kano's demonstrations, the judogi came with it. Mikinosuke Kawaishi, who taught judo in Paris from the 1930s, introduced the colored belt system to European students who needed visible markers of rank. The garment itself was imported, copied, and eventually manufactured locally in France, the United Kingdom, and later Brazil and Cuba. International competitions required uniformity, and by the 1964 Tokyo Olympics, when judo debuted as an Olympic sport, precise judogi specifications were enforced at the highest levels.

Modern judogi come in two colors: white (traditional) and blue, introduced in the 1980s for television visibility and initially opposed by Japanese traditionalists. The International Judo Federation sets minimum fabric weight requirements for international competition, ensuring the cloth can withstand the demands of elite-level throwing and grappling. A contest-grade judogi is not merely symbolic; it is equipment, designed to absorb sweat, resist tearing, and give neither competitor an advantage through its texture. The word arrived in English dictionaries in the late twentieth century, though English speakers often shorten it and say simply gi.
