History of competitive Judo

Contest ( shiai) is a vitally important aspect of Judo. Early examples include the Kodokan Monthly Tournament (Tsukinami shiai) and the biannual Red and White Tournament (Kohaku jiai), both of which started in 1884 and continue to the present day.

In 1899 a committee of the Dai Nippon Butoku Kai chaired by Jigoro Kano drew up the first formal set of rules for Judo contests. Wins were by two ippons, awarded for throwing the opponent onto his back or by pinning them on their back for a "sufficient" amount of time or by submission. Submissions could be achieved via shime-waza or kansetsu-waza. Finger, toe and ankle locks were prohibited. Contests were set at 15 minutes long. In 1900, these rules were adopted by the Kodokan with amendments made to prohibit all joint locks for kyu grades and added wrist locks to the prohibited kansetsu-waza for dan grades. It was also stated that the ratio of tachi-waza to ne-waza should be between 70% to 80% for kyu grades and 60% to 70% for dan grades.

In 1916, additional rulings were brought in to further limit kansetsu waza with the prohibition of ashi garami and neck locks, as well as does jime. These were further added to in 1925, in response to Kosen Judo ( Kōsen jūdō), which concentrated on ne waza at the expense of tachi waza. The new rules banned all remaining joint locks except those applied to the elbow and prohibited the dragging down of an opponent to enter ne waza.
