Hakko Ryu Jujutsu Shodan - Yondan 4 Book Lot by Ryuho Okuyama (Preowned)

Hakko Ryu is a Japanese jujutsu style founded in 1941 by Ryuho Okuyama, derived from Daito Ryu Aikijujutsu. It focuses on self-defense by targeting meridian pressure points to create intense but non-damaging pain for control, emphasizing subtle movements over strength. Often paired with Koho Shiatsu therapy. "Hakko" means "eighth light" (infrared-like subtle power).
