Recently I have added Tenshinsho Jigen Ryu to my practice. Tenshinsho is an active,combat form of sword that appears to be very obscure in the United States.Unlike other Iaido forms that I have been aquainted with, Jigen ryu is dynamically aggressive and maintains a primary marriage to combat sensibility .However, it is also the most compatable form of sword with Aikido movement that I have ever been exposd to. The persitance of attack and the speed with which we draw is amazing to combine with aikido. It is very alive.
I am fortunate to train with Phil Ortiz Sensei of the NYC Budokai.
