John Quinn Sensei (RIP)

An expert in Masaki Ryu classical martial arts and a direct student of Nawa Yumio Sensei

John Quinn Sensei was a member of the SMAA Board of Advisors. Quinn Sensei lived in Japan for over 20 years where he studied karate-do, jodo, and forms of koryu bujutsu ("old-style martial arts"). In particular, Quinn Sensei is expert in the ancient Masaki Ryu. The Masaki Ryu is perhaps best known for its use of the manriki kusari (weighted chain) and kusari-gama (chain and sickle).

Quinn Sensei was a direct student of Nawa Yumio Sensei, the 10th generation Headmaster of Masaki Ryu. He received high-level teaching certification from Nawa Sensei, and he was the founder of the Masaki Ryu Bujutsu Kenkyukai.

Quinn Sensei was one of only a handful of people--anywhere in the world--licensed to teach Masaki Ryu. He lived in Virginia, where he taught this time-honored martial art.
