"Nice performance" is not indicative of "good kata": Many people have been kind and said things like "I like your kata on youtube". Even though I appreciate these `warm fuzzy' compliments, this type of 'nice comment' is unclear to me. If someone likes my kata I hope that means they can see what I am doing as being 'effective martial arts', even if they are unsure of the application/principles of Asai Sensei's IJKA Shotokan-ryu. Asai Sensei once said "most of the kata champions now can't do good karate, only winning karate".
The difference between BUNKAI & OYO: I've said this before and will say it again... "Bunkai is analysis, think of Nakayama Sensei's 'Best Karate' applications. These are not the actual practical applications but rather analyzing the movements for correct fundamental performance so the movements/positions are correct" (i.e. - like the Junro-shodan 'bunkai' featured in the photo). "This type of practice is useful when learning a respective kata for the very first time. It is NOT FOR ONGOING PRACTICE. Oyo on the other hand is practical 'application' for actual self-defence. Oyo makes is what makes every kata a lifelong challenge to master".
