Taught by a senior master-teacher with law enforcement, military, and field-tested experience.

In a martial arts world frozen in form and movement... KUDEN! Radio exists to revive the living transmission of wisdom that once passed quietly from teacher to student.
These are the kinds of lessons shared after class. Over tea. When the dojo emptied and the real teachings began.
Rooted in Kuden (oral) and Shinden (heart) transmission, and fused with the Ninja's path of modern learning (Ninja no Kyomon), this podcast delivers the strategy, mindset, and clarity needed to live — and protect — a life, your life of purpose.

KUDEN! Radio is hosted by Dai-Shihan Jeffrey M. Miller, senior student of Soke Hatsumi and one of the longest-practicing Western masters of Bujinkan Ninjutsu.
In this podcast, he brings together ancient warrior teachings and modern disciplines like psychology, neuroscience, body language, NLP, and leadership to help you:
Sharpen your warrior and shinobi mindset
Apply wisdom from kata into daily life
Break free from fear, confusion, and internal sabotage
Protect what matters most: your mission, your family, and your future
Joining him is Sensei James Alexander, a Nidan and long-time practitioner of authentic Japanese Ninjutsu for nearly two decades. As the show’s co-host and behind-the-scenes producer, he brings a grounded student perspective while managing the technical engine that keeps KUDEN! running.
New episodes air live every Monday at 8 PM Eastern across Youtube, Facebook, Linkedin, and X.com (formerly Twitter) platforms. Distributed to 100's of major and leading podcasting sites and directories shortly thereafter.
