What is the Koga Ryu Ninjutsu Society (KRNS)?
The Koga Ryu Ninjutsu Society deals extensively with the teaching and practice of Koga Ryu Ninjutsu in its most historical and authentic form. Our goal is to keep this ancient art form from extinction by consulting related historical texts, performing ethno-archaeology, and reconstructing ancient practices through experimentation. Our aim is to establish a governing body for providing authentic Koga Ryu Ninjutsu and thereby setting the standard for ranking students and instructors.
