Seidokaikan (正道会館) is a traditional full contact karate derived from Kyokushin by Kazuyoshi Ishii. Seidokaikan organized the first professional full contact karate tournament named the Karate World Cup. The Karate World Cup had special extension rounds; if the judge's decision was deadlocked after an extension round, the rules then allowed face strikes with fighters donning boxing gloves (kickboxing).
