Bunkai

, literally meaning "analysis" or "disassembly", "is a term used in Japanese martial arts referring to process of analysing kata and extracting fighting techniques from the movements of a 'form' (kata). The extracted fighting techniques are called Oyo."

==Process== Bunkai is usually performed with a partner or a group of partners which execute predefined attacks, and the student performing the kata responds with defenses, counterattacks, or other actions, based on a part of the kata. This allows the student in the middle to understand what the movements in kata are meant to accomplish. It also illustrates how to improve the technique by adjusting distances (Maai), timing, rhythm (Ritsudo) and fluidity (Nagare) in combat properly, in order to adapt and adjust any technique depending on the size of an opponent.
