In this first video on Iga Ryu Ninjutsu, Sensei Juan Hombre transmits the teachings he received from the Grand Master and Heir Jinichi Kawakami, regarding unarmed combat, known as Atemi Taikenjutsu, a prelude to Atemi Goroshi, "The Secret Art of Ninja Combat". This system is characterized by instinctive and intensive series of blows, focusing the final shot on vital points, and whose purpose is the surprise defeat of the aggressor, preventing him from overcoming our attack. An art which is the main principle of combat for survival and which made the warriors of the shadows famous for their invincibility.
