With this post, I just want to direct interested karate practitioners to a great resource on YouTube (linked below). It is a video recording of Soke Shogo Kuniba in his dojo, where he shows bunkai (explanations) to all the movements in our five goshindo kata (Shoden 1-5). To help him, he has two of his students, Mike Doyle and Mark Boyette (both prominent practitioners of the style). The video is probably from sometime in the 80s.

Note that these kata were still in development when the video was made, and some slight differences exist compared to how we do them today.
