JYJ member and actor Yoochun will be revealing a surprise new song at the Tokyo Dome concert.

Their agency stated, "Yoochun is to reveal a self-composed song during this concert. Unlike the other members who released solo albums last year, Yoochun was busy with his acting. Because he did not release his own album, he wanted to surprise his fans with a new song."

JYJ will be holding a concert at the Tokyo Dome on April 2-4 for their, '2013 JYJ Concert in Tokyo Dome: The Return of the JYJ'.

Yoochun commented, "It has been so long since we've met our fans at the dome. I wanted to present them with a new song and decided to reveal this new song to them at the concert."
