Sei ShindoKai (True Way)

Sei ShindoKai (True Way) Defense Systems


Hanshi Shiroma founded Sei ShindoKai. He has been instructing and training in the martial arts for over 60 years and has studied a wide variety of martial arts styles at different martial arts institutions.

Sei ShindoKai is not an organization of style, but a group of individuals in the search of the truth, in self-defense, through the martial arts.

Techniques are for fit for the individual. Some of the techniques are designed for large strong men. Other techniques are for women and smaller people to defend against a larger attacker.  All techniques are tested for usefulness, are relatively easy to learn and highly effective.

The self-defense classes are only taught in a private or semi-private setting to allow each individual to learn suitable techniques to take advantage of their unique strengths.

  • Sei ShindoKai affiliation does not require an individual or studio membership fee and is available to any style of martial arts.
  • Sei ShindoKai defense tactics are equal or superior to Krav Maga, FBI, Canadian Police, Navy Seals, Special Forces, SWAT and Recon tactics.
