Koppojutsu is a method of fighting that specializes in the control and destruction of bone and cartilage.

Its learning needs to have the talent, the breath subtle feel adequate, rhythm, and finally far from assimilating a basic form. Contrary to popular belief, Koppojutsu is the art of breaking and/or crush the bones in a frontal way. It would be rather a specific paradigm and a mindset to adopt, in which there is a presence to be felt in the deep bone structure of the human body. Koppo can be expressed as a technique that attack the same core.
