The latest Johnny's International e-mail has been sent out and came with an announcement for Akanishi Jin to be a guest judge at the Kollaboration 11 in L.A.'s Nokia Theatre on November 5th. Kollaboration is an entertainment concert for Asian Pacific Islander's to participate in so they have a creative outlet.
You can check out the Kollaboration website here.
And while it doesn't mention him performing I'd be surprised if Jin doesn't at least perform his upcoming U.S. single, as I'm sure this is a part of promotion for it. And if not it's another good chance for Jin fans in the L.A. area to at least be able to see him.
