Thank you for all wondeful videos. I was looking for the briefing of all Katas Musoshinden Ryu and I finally found them, not only the fluently briefing but also wonderful online lectures. First of all I would like to watch all of Katas through and practise step by step. Thank you again with all my respects to Kawaguchi Sensei.
Unfortunately, I do not have Kawaguchi Sensei’s Seitei Iai video; however, there is an online subscription service at gen-universe.com/ where you can find it, and many other training videos. I have yet to subscribe, but plan to when I have time for viewing.
