TVXQ will celebrate its 20th anniversary with a full-length album, a concert and an exhibition.

The theme of the 20th-anniversary events will be "20&2," representing (20th Anniversary & Two Members).

"'20&2 (20th Anniversary & Two Members)' will be a moment to look back on the meaningful times and records TVXQ had over the years and a start for a brand new journey that the two members, U-Know Yunho and Max Changmin," SM Entertainment said in a press release Thursday.

The 20th-anniversary celebration starts with the release of TVXQ's ninth full-length album on Dec. 26, the day the boy band debuted in 2003. It will be the band's first Korean album in almost five years.

The album release will be followed by a concert and an exhibition that will look back on the history of TVXQ, alongside the duo's television appearances, according to SM Entertainment. Details of the planned events are yet to be announced.

TVXQ debuted as a five-member boy band in 2003 with its first single "Hug" under SM Entertainment. Three members of the band, Kim Jae-joong, Park Yu-chun and Xia, left SM Entertainment in 2009, saying there were unfair clauses in their exclusive contracts with the agency.
