He is a member of the Korean pop group JYJ, and was one of the original members of boy band TVXQ.

XIA made his debut in 2003 as a member of TVXQ, a boy band produced and formed by South Korean record label and talent agency S.M. Entertainment, having previously been a trainee for six years. He had released four Korean albums, four Japanese albums, thirty Japanese singles and several Korean singles during his first six years in the music industry as TVXQ. In 2009, Kim and fellow TVXQ members Kim Jaejoong and Park Yoochun filed a lawsuit against SM Entertainment, arguing that their exclusive contracts were unilaterally disadvantageous towards the artists and should be invalidated. The Seoul Central District Court ruled in favor of the three and granted an injunction suspending their contracts. The trio reunited and subsequently formed JYJ (formerly known as JUNSU/JEJUNG/YUCHUN in Japan). As JYJ, Kim has released one English album, one Korean album, one Japanese EP, and one Korean EP.

Kim began his solo career in 2010 with the release of Japanese single "Xiah", which peaked at number-two on Japan's Oricon singles chart. The same year, he took the role of Wolfgang in his debut musical Mozart!, receiving critical acclaim and commercial success. After the release of Xiah, Kim's solo music career was sent into hiatus because of a discord between him and his Japanese label Avex Trax that led to the sudden suspension of all his activities in Japan. In May 2012, he released his first full-length Korean solo studio album "Tarantallegra", while being represented by new management agency C-JeS Entertainment. Following the release, he embarked on his first headlining world tour. He returned with his second Korean solo studio album "Incredible", in July 2013.
