Jidokwan is one of the original nine schools of the modern Korean martial arts that became Taekwondo and was founded in what is now South Korea at the end of World War II. Its name translates as "School of Wisdom". The Jidokwan in Korea still exists today. It functions as a social fraternal order. Jidokwan supports and endorses the Kukkiwon method of Taekwondo, and supports the WTF.
The foundations of what was to eventually become Jidokwan were laid down by Chun, Sang Sup.
When he was seventeen years old, Chun relocated to Japan to attend College at Dong Yang Chuck Sik (Takushoku) University in Japan, where he mastered Shotokan Karate under Gichin Funakoshi. Upon his return to his native Korea, he began teaching the Karate that he had learned in Japan at the Chosun Yun Moo Kwan school of Judo. This was one of the few martial art schools that the Japanese occupying forces allowed to exist during this period of military occupation. During this time, he had a very close relationship with Byung In Yoon, who studied Chuan-fa in Manchuria and became a Shudokan Karate "Shihan" (Sabum or teacher) under Kanken Tōyama while he studied in Japan.
Chun and Yoon would travel to train with other martial artists, sometimes traveling to Manchuria. They trained with each other so much that they became known as brothers. Yoon taught class at Chun's Choson Yun Moo Kwan Kong Soo Do Bu for about 6 months before opening his own club called the YMCA Kwon Bop Bu. Yoon's YMCA club later became the Chang Moo Kwan, which he founded with his most senior student, Nam Suk Lee.
During the Korean War, all schools of martial arts were closed in Korea. This was also the case with the Chosun Yun Moo Kwan. Sang Sup Chun and Byung In Yoon both vanished during the Korean War. Sang Sup Chun has never been heard from since the Korean War. Byung In Yoon died of lung cancer on April 3, 1983 in Cheong-jin City, Ham-Gyoung North Province.
The Jidokwan still exist in Korea today and functions only as a fraternal order which endorses the Kukkiwon system and supports the World Taekwondo Federation.
