JYJ's Jaejoong held a secret party event with 25,000 fans in Japan. Jaejoong suggested the idea of holding this event to celebrate his birthday with fans.
Jaejoong signaled the beginning of the event, by moving from the back of the audience to the stage in a gondola. He performed a cover of Hideaki Tokunaga's "Bokuno Sobani" and YUI's "Goodbye Days".
He also had a drama parody corner, where he put a sauna towel wrap on a fan's head, fed a fan, gave a fan a back hug, and took Polaroid picture with the fans. Fans prepared a birthday cake and video message from fans all over the world as well as his fellow JYJ members Yoochun and Junsu.
Jaejoong also performed "9+1#", "Light", and Nakashima Mika's "Glamorous Sky".
Meanwhile, Jaejoong will hold his '2014 KIM JAE JOONG J-PARTY IN SEOUL' at Jamsil Arena on January 26.
