Ji Han-jae (; Chi Hon-tsoi) is one of the highest ranking hapkido instructors in the world and founder of Sin Moo Hapkido who appeared in the movie Game of Death with Kung-Fu master Bruce Lee. Trainee 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 () 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.

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 (; 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. In addition, Ji's original Sung Moo Kwan () shared space with people who trained in other arts, including Western boxing. Ji and his senior students developed tactics
