Jita Kyoei Judo Club



The traditional rules of judo are intended to provide a basis under which to test skill in judo, while avoiding significant risk of injury to the competitors. Additionally, the rules are also intended to enforce proper etiquette.


  • Ippon (one point) is a winning score.
  • Waza-ari (half point) is near ippon. If the contestant is awarded two ippons, they will win by waza-ari-awasete-ippon (two waza-ari make an ippon).
  • Yuko (advantage) are different from waza-ari in that no amount of yuko will be equivelent to the next higer score.

If the match is not decided by an ippon, then it will be decided based on who has better scores. If the score is completely even, then the contestants will fight again, or the judge declares a draw. If the contestants fight again, then the winner is the first person that scores. This is called the golden score.

The main judge declares who gets what points. The corner judges will signal if they disagree with the main judge which the main judge will take in to consideration.

Shido (Penalties)

  • passivity or preventing progress in the match.
  • safety offense for example by using prohibited techniques, or for behavior that is deemed to be against the spirit of judo.

The first shido serves as a warning, the second gives a yuko, the third a waza-ari, and finally the 4th shido is announced as hansoku-make and gives the opponent an ippon.


Judo was introduced into the Olympic Games in 1964 and is practiced by millions of people throughout the world today. People practice Judo to excel in competition, to stay in shape, to develop self-confidence, and for many other reasons. But most of all, people do Judo just for the fun of it.
