XIA

Kim Jun-su, also known by the stage name XIA is a South Korean singer, model, dancer and stage actor. He is a member of  JYJ, and was one of the original members of TVXQ.

Kim made his debut in 2003 as a member of TVXQ, a boy band produced and formed by South Korean record label and talent agency SM 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/JAEJOONG/YOOCHUN in Japan). As JYJ, Kim has released one English album, two Korean albums, one Japanese EP, and one Korean EP.
