MISSION
Mission & Three Pillars
The federation promotes and develops “Combat Karate,” which harmonizes the spirit of budo with the practicality of combat sports, to foster the healthy development of young people and contribute to local communities. We advance safe, fair competition and educational instruction, contributing to regional sports and martial-arts culture.
1. Healthy Development of Youth
Through instruction combining the courtesy-centered spirit of budo with practical combat technique, we nurture young people healthy in both mind and body.
2. Competition Operated with Safety First
We minimize participant risk through head-safety standards (GRTP-protocol compliant) and a weight-class system (a body-index of height + weight for gi-grappling rules; conventional weight classes for kickboxing rules).
3. Community Contribution & International Exchange
As a certified community club across the three cities of Ikeda, Kawanishi and Takarazuka, we deepen local ties while continuing technical exchange with affiliated dojos overseas.
