|Real Name||Kim Jun-su|
Kim Junsu (born December 15, 1986; registered on January 1, 1987 in Gyeonggi-do, South Korea) better known by his stage names Xiah, Xiah Junsu (in South Korea) or simply Junsu (in Japan). He is a Korean singer-songwriter, composer and occasional actor. He is a former member of South Korean boy band TVXQ, and a member of JYJ.
Xiah was born and raised in Gyeonggi-do, South Korea. He has an older fraternal twin brother named Junho. He was the first member to join TVXQ. Xiah auditioned for SM Entertainment with best friend Eunhyuk from Super Junior. Eunhyuk didn't make the audition that year but Xiah made it. Xiah joined SM Entertainment at the age of twelve after winning a televised audition judged by two members from H.O.T., Moon Hee Jun and Kangta. He debuted with the group, during a BoA and Britney Spears showcase.
He chose Xiah to be his stage name, explaining that the name was short for "Asia", as Asia is pronounced "ah-shee-ah" in Korean. "Xiah" would be an implication of his desire to become not only a star in Korea, but also a star recognized all throughout the continent.
In 2002, Xiah participated in the 6th Annual Starlight Casting System, which led him to be casted by SM Entertainment to take part in TVXQ. He also participated in Samsung's Anycall project, Anyband. The group consisted of label-mate BoA, Tablo of Epik High, and jazz pianist Jin Bora. The group has only released one single, "AnyBand". In 2006, he collaborated with label-mate Zhang Liyin, for her debut single "Timeless. Xiah wrote and composed "Nae Gyeote Sumsiur Su Ittdamyeon (White Lie)" (네 곁에 숨쉴 수 있다면), which was included on TVXQ's third studio album, "O"-Jung.Ban.Hap.. For the Trick project, he composed his solo "Rainy Night". Xiah also wrote "Noeur.. Baraboda (Picture of You)" (노을..바라보다), which was featured in the group's fourth Korean album, Mirotic. For the Tohoshinki 4th Live Tour 2009: The Secret Code in Tokyo Dome, Xiah performed his self-composed song Xiahtic in Japanese.
Xiah has appeared on two televised shows with TVXQ, Banjun Theater and Vacation.
