Kim Junsu
South Korean singer from band JYJ
Kim Jun-su (Korean: 김준수; born December 15, 1986), known mononymously as Junsu or by the stage name XIA ( SHEE-ah; 시아), is a South Korean singer-songwriter and musical actor. He is a former member of JYJ, and was one of the original members of TVXQ, during which time he was known by the stage name Xiah Junsu (시아준수).
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. During his time in TVXQ, the group released four Korean albums, four Japanese albums, thirty Japanese singles and several Korean singles. 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 in 2010. JYJ has since released one English album, two Korean albums, one Japanese EP, and one Korean EP.
Kim began his solo career in 2010 with the release of the Japanese EP Xiah, which peaked at number two on Japan's Oricon Singles Chart. Later that year, he made his musical debut in the role of Wolfgang in Mozart!, receiving critical acclaim and commercial success. In May 2012, he made his solo debut in South Korea with the studio album Tarantallegra and embarked on his first headlining world tour.

Why this record matters
The phrase “south Korean singer from band JYJ” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Chronology provides the most reliable spine for this subject; interpretation should follow only after identities and dates are secure. The source revision retrieved here is dated Aug 31, 2026. The linked authority identifier is Q482783. VIAF identifies the subject as 217148995853859750930. 2 of 3 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank. The first chronological checks are 1986, 2003, 2009 and 2010.
Public reputation and documentary evidence do not always develop together; absence from a summary is not evidence of historical absence. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
