Bujinkan Taihenjutsu Muto Dori Kata
In these training exercises from the ten ryaku no maki, we work with our training partner to move out of the way of an incoming sword cut.
The first lesson is to understand distance- what is the distance of the attack and when do you move?
Move soon and you will be tracked, move later and you will be cut.
Building on this, moving in unison with the attack, at the last moment so your training partner *thinks* they have cut you.
Getting hit and getting hit often as you wait to the last moment in practice helps understand that lesson.
