or
dogi is a uniform for training, used in martial arts derived from
Japan, or
budo. (
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
Kano Jigoro. Japanese martial arts historian
Dave Lowry speculates Kano derived the uniform's design from the uniforms of Japanese firefighter's heavy hemp jackets called "hanten." By 1920, the keikogi as it exists today was worn by Kano's students for judo practice. The
Kodokan (judo headquarters) has a photo taken in 1920 that shows Kano wearing a modern keikogi.
