The World Katsudo Association (WKA) empowers martial artists through the disciplined study of Dageki (striking) and Kumi (grappling), the two foundational elements of the Katsudo system. Rooted in tradition yet adaptable to modern practice, Katsudo offers a comprehensive martial path that emphasizes both physical excellence and personal development.
WKA competitions and training emphasize safe, skillful, and principled engagement, guided by the enduring values of respect, discipline, and lifelong learning. These values inform every aspect of our approach—from technical instruction and event organization to the way competitors, instructors, and officials conduct themselves inside and outside the ring.
Through standardized rules, sanctioned events, and a dedicated community of practitioners, the WKA provides a clear and supportive structure for martial artists at all stages of their journey. Whether testing their skills in competition or exploring the deeper philosophical elements of Katsudo, our members are encouraged to refine their technique, uphold the spirit of martial arts, and grow as both athletes and individuals.
Dageki
Dageki
Dageki is the striking discipline of Katsudo, emphasizing control, skill, and respect. Governed by detailed rules to ensure safety and fairness, Dageki contests use a point-based scoring system and allow a wide range of legal strikes including punches, kicks, spinning backhands, and knee strikes to defined target areas.
WKA-sanctioned matches follow structured time limits, mandatory protective equipment guidelines, and clear win conditions such as knockouts, technical knockouts, and points decisions. Striking techniques are balanced with philosophical values like discipline and sportsmanship, reflecting the spirit of Katsudo.
Kumi
Kumi
Kumi is the grappling discipline of Katsudo, built on the principles of control, adaptability, and mutual respect. Structured as an open-style format, Kumi allows practitioners from diverse grappling traditions to compete under unified WKA guidelines that prioritize safety and fair play.
Contests are evaluated based on falls, positional control, and submissions. Points are awarded for takedowns, escapes, and reversals, while penalties address infractions and unsportsmanlike behavior. Victory may come through a pin, submission, or technical stoppage, or by accumulating a greater point total.
Kumi prohibits dangerous or uncontrolled techniques—such as heel hooks, suplexes, neck cranks, or strikes—to ensure the safety and longevity of every participant. WKA-sanctioned grappling reflects the core values of Katsudo: discipline, control, and the honorable testing of skill.
