TVXQ is to release a new single in Japan to continue their activities once again.

The 36th Japanese single album Catch Me- If you wanna is set to release on January 16. It will include Japanese version of "Catch Me" and new single titled "I Know."

The Korean version of Catch Me was released last October as TVXQ's sixth studio album in a year and eight months. The single already garnered attention as it has been airing as the theme song for Fuji TV suspense drama "Saki," that began airing on the 8th.

The new song "I Know" is a ballad piece expressing the feeling of a man who vows on eternal love. It's expected to be completely different from their usual powerful and charismatic song.

TVXQ will begin their five dome tour on April 27 at the Saitama Super Arena continuing through Tokyo Dome, Osaka Kyosera Dome, Fukuoka Yahoo! Japan Dome, Sapporo Dome and the Nagoya Dome.
