This notice (tentative) about his Japan 2011 Tour was posted up on U:zoosin's Kim Hyun Joong Japan Official Site yesterday.
So far, the details did not specify whether the tour is a concert tour or just a series of meet-&-greet. But from what we understand, it is going to be a showcase (i.e. with live performances) kind of fan-meet. Do correct us if you know differently.
