Kumi is the grappling discipline of Katsudo, focused on control, fluid movement, and technical precision. With its open-format structure, Kumi invites martial artists from diverse grappling backgrounds to test their skills under a unified and principled rule set. Governed by safety, sportsmanship, and adaptability, Kumi embodies the deeper spirit of disciplined combat.
Kumi places high value on mutual respect, safety, and clean execution. Techniques must demonstrate control rather than brute force. Athletes are expected to maintain composure, honor referee decisions, and embody the principles of the WKA at all times.
Bouts consist of up to three rounds, each 3 minutes long, with 90 seconds of rest between rounds.
If a draw occurs after regulation, a sudden victory round begins with no time limit, ending upon the first point or fall.
All matches are conducted in a WKA-approved ring or enclosure, overseen by certified referees and officials.
Falls (2 of 3 required):
Pin: Opponent's shoulders controlled to the mat outside of Guard positions.
Submission: Tapping or verbal yield from a legal, controlled technique.
Technical Stoppage: Referee ends the match to prevent injury from a dominant hold.
