The Griffith Park Bujinkan (BujinkanGP) training group was established in 2017 to provide Franklin Canyon Bujinkan members with an additional location to practice in preparation for training in Japan. 

BujinkanGP instructors are licensed by Dr. Masaaki Hatsumi, the head of the international Bujinkan martial arts organization based in Japan and travel regularly to Japan and abroad to train with the Grandmaster Masaaki Hatsumi, the Japanese Dai Shihan’s, and other chief instructors around the globe. 

The original training group, Franklin Canyon Bujinkan (BujinkanFC), was established in 2012 by Sensei David Greenberg, after decades of training and teaching in Japan and abroad.
