"Bunburyodo" comprises the original non-sports training concepts and directions from Uechi Kanbun Sensei, as preserved and passed on by Toyama Seiko Sensei, Kanbun Sensei's last actively-teaching student. I am Toyama Sensei's student, and the only foreign practitioner of UechiRyu to be promoted to Kyudan (9th Dan) by a direct student of the founder, Uechi Kanbun Sensei.
Of greatest importance are the concept of softness above all, and that the Budo Arts were never intended to be used as sports.
It's my belief that these concepts and training directions are not exclusively restricted to UechiRyu system, but can apply equally well to any system or style of karate or martial art.
