Ji Han-jae

After Ji moved to the U.S., he attracted a large number of students interested in learning hapkido, especially his Sin Moo style. He teaches several seminars a year in North America, Latin America and Europe. He currently lives in Tucson, Arizona. In 2017, he went to Queens, New York and had a reunion with his Hapkido co-star Angela Mao at her restaurant.

In 1984, Ji Han-jae moved to the United States and founded Sin Moo Hapkido (Korean: 신무 합기도). Before Ji left Korea, his close friend Myung Jae-nam, the head of the International H.K.D Federation, awarded Ji the rank of 10th dan.

Many people consider Ji the founder of hapkido, while others credit his teacher Choi Yong-sool, who referred to his art as yawara (Korean: 야와라; 柔) or yukwonsul (Korean: 유권술; 柔拳術)". It is commonly claimed by his students that Ji was the first to use the name hapkido for the techniques he was teaching at that time. Choi's first student Seo Bok-seop, however, said in a 1980 interview that Jung Moo Kwan was the first to use the term to refer to the art as well as the symbol of the eagle to represent hapkido./ Regardless, part of the kicking techniques used in the many styles of hapkido is marked by changes implemented by Ji and Kim Moo-hong (Korean: 김무홍; also rendered Kim Moo-woong or Kim Moo-hyun) who was also a student of Choi. After studying with Choi, Kim went to a Buddhist temple and learned a kicking art there. Traveling to Seoul in 1961, he lived and trained with Ji for eight months and together, implementing the kicking methods they had both learned, they finalized the kicking curriculum for hapkido, significantly expanding it to include kicks to higher targets and spinning and jumping kicks, none of which were originally part of Choi's system.

Ji Han-jae's political career began to rise quickly when he started teaching hapkido to the president's bodyguards at the Blue House. In 1979, however, President Park Chung-hee was assassinated. Most of those close to Park resigned including his presidential bodyguards and their martial arts instructors, including Ji.

On his first trip to America, Ji appeared in the film Game of Death with Bruce Lee. Ji opted not to appear in the additional footage shot for the 1978 version of the film. He also appeared in the film Hapkido (aka Lady Kungfu) with Angela Mao.

Later in 1973, seeking to consolidate three of the larger hapkido organizations that had grown over the years, Ji merged his organization with the Korean Hapkido Association, led by his contemporary Kim Moo-hong, and the Korea Hapki Association, headed by one of his former senior students, Myung Jae-nam, to form the large and influential Republic of Korea Hapkido Association (Daehan Min Kuk Hapkido Hyub Hwe; Korean: 대한민국 합기도 협회).

By 1965, Ji was hapkido instructor for the presidential guard at the Blue House and thereby became acquainted with Park Jong-kyoo (Korean: 박종규), chief of the country's security forces. Unhappy with his lack of input in the Daehan Kidohoe, with political connections and an ever-growing support from his Sung Moo Kwan students, he decided to form his own organization the Korea Hapkido Association (Korean: 대한 합기도 협회) with Kim Woo-joong (Korean: 김우중), president of Daewoo Corporation, as the new association's first head.

In 1963, Ji was a founding member of the first attempt to create a large organization to include hapkido. Called the Korean Kido Association (Daehan Kidohoe; Korean: 대한 기도회) Choi Yong-sool was elected the first titular chairman with the organization's charter constitution authored by Ji, Choi and Kwon Jang. The association's purpose was to promote martial arts in the public school system and to police officers and government officials. Ji was highly instrumental in organizing this group but Choi appointed another of his top students, Kim Jeong-yoon (Korean: 김정윤), to a position above Ji, greatly diminishing his influence.

In 1961, Kim Moo-hong came to visit Ji and they developed many of the kicking techniques the art is known for.

In 1959 Ji Han-jae combined all of his martial arts knowledge and began to teach hapkido.

After less than a year, Ji relocated to Seoul, the nation's capital, in 1957. There he founded Sung Moo Kwan (Korean: 성무관), which would become an influential kwan, or school of hapkido, producing many of the important teachers of the art. His first student was Hwang Deok-kyoo (Korean: 황덕규; founder of the Korean Hapkido Association) followed shortly after by Myung Kwang-sik (Korean: 명광식; founder of the World Hapkido Federation), Lee Tae-jun, Kang Jeong-soo. In 1958, students Kim Yong-jin (Korean: 김용진), Jeong Won-seon (Korean: 정원선; Retired 2007-taught in Rockford, Illinois) Han Bong-soo (of Billy Jack movie fame and founder of the International Hapkido Federation), Choi Sea-oh (First man to teach hapkido in the U.S.) and Myung Jae-nam (Korean: 명재남; Founder of the Korea-based International Hapkido Federation and Hankido). Around this time, Ji began to use the name hapkido to promote the art, shortened from the original hapki yukwonsul (Korean: 합기 유권술; 合氣柔拳術) name employed at the first school run by Choi Yong-sool and Seo Bok-seob in Daegu in 1951.

Leaving Daegu for his hometown of Andong, Ji opened his first school, Anmoogwan (Korean: 안무관), in 1956, still calling his art yukwonsul at this time. His earliest students from this period were Kwon Tae-man (Korean: 권태만; who teaches in California today), Yoo Young-woo (Korean: 유영우) and Oh Se-lim (Korean: 오세림, former president of the Korea Hapkido Federation).

Born in Andong, Gyeongsangbuk-do, South Korea On October 27th 1936, he began his martial arts training in 1949 under the direction of Choi Yong-sool (Korean: 최용술) and reached the rank of 8th dan under Choi. Ji trained with Choi until 1956, when he moved to Seoul to open a school of self-defense in the nation's capital. Ji trained in the ancient methods of the Korean martial arts, known as Sam Rang Do Tek Gi by a man named Taoist Lee. Though this man's identity can not be confirmed, he is believed to have he trained Ji in meditation, the Korean long staff jangbong (장봉; 長棒)", short staff danbong (단봉; 短棒)" and the unique kicks of Sam Rang Do Tek Gi.
