Master Sosai Masutatsu Oyama, Founder of Kyokushin
TETSUJIN KAI
Tetsujin Kai exists not to teach a standalone style, but as the blueprint and physical means to temper any martial artist into a Tetsujin, an Iron Warrior.
With classes rooted in Kyokushin, Taekwondo, Kickboxing and Sumo, we utilize a cross-system methodology in our training practices. In addition, we further sharpen our skills through sparring frequently within our network of local gyms who are also dedicated to testing the absolute limits of human endurance and fortitude.
Recognizing that true martial prowess transcends style boundaries, the Tetsujin Kai approach provides a unified, non-partisan framework where practitioners of all disciplines can forge an Immovable Iron Spirit (Fudo Shin).
Through relentless physical challenge, continuous self-cultivation, and the transformative suffering of combat endurance, this methodology tempers the Iron Men and Women of the modern era, proving that while styles may differ, the truth that iron sharpens iron is universal.
