The road to the senior black belt ranks requires many years of service and dedication to the WTSDA. What does it take to be a WTSDA Ko Dan Ja? Achieving Ko Dan Ja (4th Dan and above) requires an individual who is well rounded in all aspects of Tang Soo Do (physical, mental and spiritual). Characteristics of Ko Dan Ja include technical and non-technical skills and knowledge, good character, commitment, dedication, and loyalty. Ko Dan Ja practice lifelong learning as well as passing this knowledge to students.

Region 1 is fortunate to have some incredibly skilled, talented, and knowledgable Ko Dan Ja as members of our region.
