General AJDM Overview

The AJDM represents an opportunity to:
  • Promote the maxims of Judo: strive for perfection as a human being, maximize efficiency of motion and energy, and focus on mutual welfare and benefit.

  • Introduce Judo as a foundational development sport and/or as a cross training activity.

  • Grow judo by making it more accessible, appealing and participant friendly, regardless of age.

  • Contribute to increasing Americans’ physical fitness, mental/emotional resilience and building life skills such as respect, courage, leadership and working with others.

  • Align better with research-based, age-appropriate development recommendations.

  • Support and reinforce a longer-term view of participation, a “Judo for life” philosophy, which in turn can drive recruitment and retention.

  • Collaborate with the American Judo Alliance organizations and local dojos to provide a consistent, positive experience from youth to adult, from beginner to advanced.

  • Clarify expectations and satisfy the question “why Judo?” with a well-articulated, data-supported, and holistic pathway to learn, grow and achieve one’s personal best.

  • Elevate the proficiency and effectiveness of the American Judo Alliance infrastructure and core stakeholders: participants, dojo owners, coaches, tournament directors, referees, parents, volunteers, and paid staff.

  • Exemplify a deep commitment to excellence in mind, body and spirit.

  • In addition to long-term athlete development the AJDM’s reach extends to coaching development, referee development and club/dojo owner development, all for the benefit to grow and improve American Judo.
