The Way of the Ninja

Ancient Secrets for the Modern World

Developed by Martial Arts Black Belt Hall of Fame Member, An-Shu Stephen K. Hayes. To-Shin-Do training covers a wide variety of methods: 

  • Striking, kicking, and punching

  • Grappling, throwing, and joint locking

  • Self-defense when pulled to the ground

  • Stick, blade, cord, and projectile defense

  • Successfully handling surprise attacks

  • Surviving against multiple attackers

  • Overcoming psychological intimidation or bullying

Unlike most other martial arts that emphasize willing competition to defeat an adversary. We aim to get out and away with the least amount of effort. The principles of To-Shin Do are based upon strategic angling, distancing, and timing.


These principles are supported by the gradual development of intuitive awareness or knowing what is needed at any given time.

To-Shin Do will teach you to be calmer, subtler, and more in control when a conflict arises.


The goal of Nagayama Dojo is to provide a path for willing explorers, that promotes confidence, clarity, community, and collaboration. We do not promote violence, however, we are very aware that we must be prepared to protect ourselves and our loved ones, rather than be victims.
