History of the Kodenkan Yudanshkai
In 1964 Joe Holck came to Tucson, AZ on request from his brother Roy Holck to take over the Kodenkan of Tucson Dojo he had started. Joe Holck accepted and ran the school as his own. The original school grew into an organization, also founded by Joseph Holck and his family in 1967, and is known as the Kodenkan Yudanshakai, which has well over 100 black belts promoting the concepts of Professor Okazaki throughout the United States.
In 1994, Joseph Holck Dai Shihan retired from active teaching and appointed his son, Vinson, to oversee the running of the organization. In 2012, the Kodenkan Yudanshakai promoted Vinson Holck to the rank of 10th Dan, and invested him with the title of Dai-Shihan.
In March of 2013, the Kodenkan Yudanshakai was incorporated as a 501.3.C non-profit, governed by a Board of Directors.
