An Olympic sport since 1964, judo is derived in part from jujitsu,
the hand-to-hand combat technique of ancient samurai warriors.
Developed by Dr Jigoro Kano in the 1880s, judo came into the Olympic
family when Japan chose to add it, being the host country, to the Tokyo 1964 Games. Out of the original four weight classes,
the hosts promptly won three.
Women's judo came into the Olympic Games at Barcelona 1992.

An ippon (10 points) wins the contest. This is acheieved by throwing
an opponent flat on their backs with control and force, by holding them down
for 25 seconds, or by a stranglehold or arm lock until submission.
Below the Ippon, various scores are awarded.
Waza-ari (7 points):
Awarded for almost getting an Ippon -- throwing an opponent on their back but without
control and force or holding them down for 20-24 seconds. Two waza-ari scores by a
competitor are the equivalent of an ippon and end the contest.
Yuko (5 points):
Awarded if a player made a throw but their opponent landed on their side instead of flat
on their backs or a hold for between 15-19 seconds.
Koka (3 points):
Awarded for a throw onto the thigh or buttocks or a hold for between 10 and 14
Yuko and Koka scores are not cumulative, so the competitor needs to
secure a better throw.
