I don’t know Paul, I think if you do a direct translation of all the Japanese phrases into English in the JSA, you could train well enough to be as good as any “traditionally” trained student.

We don’t become better students because of the arts history or that it is exotic, we become better students because we practice swinging swords. You can only judge a person’s ability by what they bring to the floor, if they have been diligent and honest in their training, that will show on the floor regardless of what you call the kata.
