Yep.Good stuff! Very Okinawan looking in his fighting techniques: Quick combos, close-in attacks, upright stance... Many of his techniques are found in kata, much to the dismay of those who maintain kata is not for combat. Modern Shotokan can use more of his influence, IMO. Asai reminds me of a young Funakoshi. He's not so much "revolutionary" as the title says, but rather reactionary, heeding back to the Shotokan's early years.
I think he also added in Chinese Kung Fu he learned from a family member and Okinawan weapons into his total repertoire.
He was definitely an original.
Twenty years after his passing, āmodernā Shotokan still has not caught up with him.
