Kyokushin World Tournament Open

World Open Karate Championship is the largest competition in Kyokushin Karate. This tournament is arranged every fourth year in Tokyo.

Rules

All world open tournaments operate under knockdown karate rules which involve standup bareknuckle fighting with basically no protection. The more characteristical rules in knockdown karate compared to other styles are that you are not allowed to punch in the face and a point system that only counts hits that actually "hurt" the opponent. This makes knockdown fighting very physical but at the same time quite safe considering that there are very few hits to the head. There can be slight variances in the rules between the different organizations responsible for a tournaments although the basics are the same. The rules have also been modified over the years.

Normally knockdown rules include:

  • No protectors or guards are used, with the exception of groin guards and protection of the teeth.
  • 3 minutes match time
  • The fighter that achieves an Ippon (one point) will win the match and the fight is stopped. An Ippon is achieved when an attack either knocks down the opponent for more than 3 seconds or renders the opponent reluctant to continue the fight. An ippon can also be granted if an illegal technique is used or the other fighter is disqualified.
  • A fighter can also win the fight by Waza-ari (half point) which is awarded if the opponent is knocked down for less than 3 seconds and is able to continue the fight. If two Waza-aris are achieved during the fight by the same fighter it is counted as an Ippon and the fight is stopped.
  • If no knockdowns occur, the judges can declare one fighter as the winner by overall efficiency of techniques, force and spirit.
  • In case of a draw there can be a maximum of 3 extensions (each 2 minutes long). Some tournaments will also settle draws by weight difference and the result of Tamaeshiwari (breaking of tiles)

<br /> Illegal techniques are

  • Punches to the face
