I found a very interesting video of a seminar lead by Kiwada Sensei, and I realized it was a series of videos posted several years ago. I have not seen all of the videos yet but I decided to make a play list for me to watch in order and of course to share it.
I want to thank who recorded these videos and David Pan for posting it on his Youtube channel, allowing all this kendo knowledge to be accessible to many.
Hope you find this interesting and if you know of any other useful and interesting videos please share.
Make sure to go over all the videos and see what calls your attention, I found specifically interesting the diagonal note explanation!
