To-Shin Do Happo Biken Happo Giri is one of the Kuki Shinden Ryu nine secrets of the sword as taught to Toshitsugu Takamatsu in late 1800s. An-shu says, “The principle of ‘cutting the cut’ looks like a simple way to win when your adversary underestimates you, but you need bravery, precision, and well-practiced skill to make it work. We show you the secrets for Happo Giri as part of our dojo’s program for earning 4th Degree Black Belt, as I learned it in Japan from my teacher in the mid-1970s.”
