Kamae and their use in defense Now in one place on one video the primary postures from each of the 9 Ninjutsu schools are shown. Shihan Van Donk demonstrates each posture, teaches how to get in them, how to move from them, how to flow from posture to posture while learning their proper names and how to apply them in combat. Do you really know these postures and their Japanese names and how to use them? If not, here is your video. Postures (also known as stances) are the fundamental foundations to your martial arts ability and determine your ability to defend yourself. Proper positioning can be everything and knowing how to move in and from them maybe even more important. There are 9 ryu (schools) in the Bujinkan Ninjutsu training and each school may offer different kamae (postures) often confusing even the best instructors. Practice posture to posture until you are very comfortable moving from one of the other with Posture Power.
