Ninja Motivation & Influence
“I can’t believe how well this program works! This method doesn’t just make people do what you want, it gets me to take control of how I communicate so that people actually WANT to do the right thing!”
Orane Harris
Ninja Motivation and Influence Program
“While this 6 step model isn’t very different from what I do anyway, my biggest a-ha moments involve having more of a framework and structure to my approach. The NMI framework is more organized and I like having a script to follow. In fact, I now write out the key points and have them there for reference in front of me on the notepad I’m using when working with a patient. Something I’ll do until this becomes second nature.”
Dr. Joshua Blum
About...
Dai-Shihan Miller
Meet Your Teacher: Dai-Shihan Jeffrey M. Miller SPS, DTI
Dai-Shihan Miller is one of the longest-practicing Western instructors of authentic Bujinkan Ninjutsu. He has trained for over four decades with top teachers across three continents — including senior Japanese shihan and senior Western instructors...climbing the ranks to become a personal student of Grandmaster Masaaki Hatsumi himself.
He is also a long-time student of Rev. Jikai Choffy in the Tendai lineage of Japanese Mikkyo (esoteric Buddhist mind-science), adding a unique depth to his approach to the Ninja's Seishin Tki Kyoyo levels - one that blends physical technique with spiritual and strategic life mastery.
A Personal Note From Dai-Shihan Miller...
Hello and welcome to the Online Ninja Academy...
I began my journey like many — passionate, driven, but without access to a local dojo or qualified teacher. I trained alone. I traveled when I could. I studied books and tapes (yep, that old!)... but I knew something was missing.
That’s why I built my dojo, known locally as Warrior Concepts Black Belt & Life Mastery Academy (aka Bujinkan Mori no Tora Dojo) and the Online Ninja Academy — to give students like you what I didn’t have: direct access to a master teacher where I lived, a clear path forward, and real feedback along the way, and then only when I could visit my teacher's dojo or a seminar he was teaching. We had no internet and no distance learning back then.

Today, thousands of serious students — from across the U.S., Canada, Europe, and beyond — are proving that real training, real results, and real mastery are possible... no matter where you live.
And here’s something I tell my online long-distance students all the time:
If you don’t have a dojo near you… maybe that’s not a problem. Maybe that’s the opportunity.
I didn’t wait for a local teacher to appear. I became the teacher. I built the dojo I needed — for myself, and for others like me.
So if you’ve been waiting… for the right time, the right teacher, or a dojo to magically appear — let this be your sign:
The path is here. The only thing missing is your first step.
If I can do it, so can you.
