35+ Years Of Technical
Mastery in Newmarket
Martial arts is not a commodity — it is a lineage.
A Technical Lab in Newmarket
Jitsu-Do was founded by Shihan Michael Ginn, a practitioner with over 35 years of dedicated experience in the evolution of combat science. After decades of training and instruction, Shihan Ginn recognized that the traditional martial arts landscape was often cluttered with fluff and outdated methods.
He founded Jitsu-Do as a Technical Lab in Newmarket — a space where the structural power of Chito-Ryu Karate and the ground-truth efficiency of Gracie Humaita Brazilian Jiu-Jitsu are integrated into a single, high-standard curriculum.
We don't believe in factory martial arts. At Jitsu-Do, every movement is scrutinized through the lens of biomechanics and safety. Our mission is to provide the Newmarket community with a training environment that prioritizes the 'how' and 'why' over the 'what.'
"This isn't a hobby — it's a scaffold for a more disciplined life."
Shihan Michael Ginn
4th Dan · BJJ Brown · 35+ Years
Shihan Ginn spent over three decades pursuing a single question: what actually works? Beginning in the late 1980s, he trained across disciplines with a practitioner's eye — keeping what was structurally sound, discarding what wasn't, and building a curriculum grounded in biomechanics, safety, and real-world effectiveness.
In 2009, he founded Jitsu-Do Karate in Newmarket with a clear mandate: no fluff.

What Shaped Our System
Jitsu-Do is rooted in two core systems, shaped by decades of cross-training across multiple disciplines. We kept what worked. We discarded what didn't.
Structural precision, biomechanics-based technique developed by Dr. Tsuyoshi Chitose.
Leverage-based ground fighting from one of the most rigorous BJJ lineages in the world.
Joint manipulation and redirection principles that inform our self-defense applications.
Clinch work and elbow/knee mechanics that sharpen our striking at close range.
Close-quarters centerline theory and simultaneous block-and-strike methodology.
Takedown and throwing mechanics that bridge the standup-to-ground transition.
