Keikogi
Keikogi (稽古着), or dōgi (道着), is a uniform for training in Japanese martial arts and their derivatives. (Keiko means practice, gi means dress or clothes.) The prototype for the modern keikogi emerged in the late 19th century. The keikogi was developed by judo founder Kanō Jigorō. Japanese martial arts historian Dave Lowry speculates Kanō derived the uniform's design from the uniforms of Japanese firefighters' heavy hemp jackets, hanten (半纏). By 1920, the keikogi as it exists today was worn by Kanō's students for judo practice. The Kodokan (judo headquarters) has a photo taken in 1920 that shows Kanō wearing a modern keikogi.
