Kumite refers to the fighting and self defence practices of the Goju-ryu system. There a numerous types which are all taught in classes at AOGKF. Below are some of the basic versions.
Bunkai is the application of Kata techniques and sequences on an opponent. There are many types of Bunkai included Kihon, Grading and Oyo (Variation) applications. A direct link to the Kata should always be relevant and it is best to learn from your Dojo or country chief instructor or International senior instructors. This video shows Higaonna Sensei demonstrating Bunkai for various Kata. These are not the same set of Bunkai set for AOGKF gradings.
Renzoku means to continue. In Renzoku Bunaki all whole Kata is organised in to one applied sequence where technique, timing and distance can be tested against an opponent. The most common form is Gekisai Dai Ichi Renzoku Bunkai as shown in this video.
Demonstration by Senseï Morio Higaonna and Senseï Molyneux. Yakusoku translates as ‘I promise’, meaning that the attacker promises to attack only with the agreed attack so the defender can hone and develop all numbers of skills. Anything from long distance to close quarters attacking techniques, along with chokes, joint locks and throws can all be utilised from Yakusoku Kumite practice. IOGKF has 10 Yakusoku Kumite sets created by Higaonna Sensei.
Iri Kumi is the free sparring of Goju-ryu Karate. Free, controlled exchange of techniques is encouraged between opponents to test their overall skill level, abilities and reactions in a controlled environment. Iri Kumi is divided into three levels. Iri Kumi 1 is slow motion free sparring, Iri Kumi 2 seeks speed with light to minimal contact and Iri Kumi 3 is full contact for experienced Black belts and practitioners. Levels 2 & 3 can also be referred to as Iri Kumi Ju and Iri Kumi Go.
