Yun Jung Do International 

Yun Jung Do the art of Human Development

It is a lifelong system of personal development that uses martial training to develop discipline, confidence, leadership, and ethical character

It is not a competitive sport and not focused on trophies or titles. Instead, Yun Jung Do exists to help people:
  • Develop discipline and self-control
  • Build confidence and resilience
  • Cultivate clarity, humility, and respect
  • Grow into capable, grounded leaders in their families and communities
This makes Yun Jung Do suitable for people seeking personal growth, not just physical training.

Our Origins & Lineage

Yun Jung Do was founded by Grandmaster Young Ku Yun, an internationally respected martial artist and educator with decades of experience in traditional and modern martial systems.

Grandmaster Yun established Yun Jung Do to preserve the values of traditional martial arts while adapting training for contemporary life — removing unnecessary ritual and focusing on what genuinely improves the human being.

The system continues under the guidance of senior instructors who trained directly under Grandmaster Yun, ensuring continuity, integrity, and high instructional standards.
