Grandmaster In Sun Seo (10th Dan Hapkido)
Grandmaster In Sun Seo (pronounced Suh) is also a direct student of Hapkido's founder, Grandmaster Choi Yong Sul. In 1957, he earned his 1st Dan black belt from Grandmaster Choi and advanced to 3rd Dan.
After serving in the South Korean Army during the Vietnam War, he returned to Korea, where he co-founded a Hapkido sub-style called "Kuk Sool Won" before eventually developing Hanminjok Hapkido. Since then, Grandmaster Seo has dedicated his life to the training and evolution of Hapkido.
Grandmaster Seo is widely regarded as one of the most respected martial artists in South Korea. In June 2024, he officially retired from his executive roles within the World Kido Federation and the Hanminjok Hapkido Association, passing on the organisation's leadership to his two sons, Grandmaster Scott Seo and Grandmaster Steve Seo.

World Kido Federation/Hanminjok Hapkido Association
Our membership in the World Kido Federation/Hanminjok Hapkido Association allows us to maintain our independence while allowing our members to travel internationally for additional Hapkido training and participate in global events.
These experiences expose us to various Hapkido sub-styles, providing valuable insights that help us benchmark our practice. This ensures that our training remains up-to-date, relevant, and of the highest quality. Additionally, our Black Belt members can be formally registered in Korea with the Korean Ministry of Culture and Sports, provided they meet the necessary standards of skill and commitment.
Since 2013, members of the Upper Hutt Martial Arts Academy and our affiliated New Zealand Hapkido schools have attended all major international events hosted by the World Kido Federation/Hanminjok Hapkido Association.
These include the biennial Korea Trip and Hapkido World Championships in South Korea and the alternated biennial Member Summits in San Francisco.
We also host the biennial Hapkido Oceania Cup in New Zealand—an official World Kido Federation/Hanminjok Hapkido Association event—where we frequently welcome Grandmaster Seo's eldest son, Grandmaster Scott Seo.
