From Grassroots to the World Stage

Our mission is to develop and promote the sport nationwide through youth engagement, grassroots programs, and community partnerships grounded in discipline, respect, and tradition. We are committed to preserving and sharing the cultural foundations of sumo, including an understanding of Japanese values and etiquette, while supporting educational and cultural events that strengthen communities and ensure long-term growth of sumo. Our programs, events, and educational resources are open to the public. Membership is only required for participation in sanctioned competition.
