I do agree that body mechanics are important. But, at its heart, Karate is an art or method of self-defense. The "do" aspects of character development is only a relatively new addition to Karate, and was preceded by the kata and bunkai which is the true core of Karate and seperates it from the other "dos". As a method of self-defense, it would seem to me that instruction in the defensive techniques, IE the bunkai, would be an important part of any serious course of study. To not teach the bunkai for several years is to deprive the student of the real tools of the trade and, at the same, misses out on the importance of visualizing the bunkai while doing the Kata. Are you saying that you change the kata, or just the suggested bunkai for a particular section of a kata? I don't see how kihon or ippon kumite practice equates to "practical fighting technique". For one, kihon is simply basics without a partner. Ippon kumite, as is typically practiced, doesn't involve realistic or practical attacks. It inolves a person in zenkutsu dachi stepping forward in an launching either a straight punch, reverse punch, or some type of kick. None of these are realistic attacks, and therefore the defense utilized cannot be considered practical. A more practical approach would deal with grabs, chokes, kicks, and other situations that one would face in a true self-defense scenario. That is where the true value of the bunkai can be seen. Remember, self defense has very little to do with the point kumite that we see at tournaments. It has much more to do with preventing and or dealing with realistic attacks in a decisive manner. I might actually agree with you on this. It might possibly be that we are talking about two different paths to the same destination.
