Somehow watching Tamaki Koji and Jaejoong sang "Melody" in NHK show (makes me think of him as Shuuichi Natori!
Perhaps due to him wearing Natori san's trade mark brown coat, with similar hair style that is brownish blond with kinda long bangs?
Also, due to His smiles! It really reminded me of the gentle smiles Natori San has!
Lastly, in this show Jaejoong's voice is really so sweet, soothing, and beautiful.
Natori San has released an Album of his own right? I think, with his voice actor, Akira Ishida, whose type of voice is very gentle and sweet, I imagine his voice would be like Jaejoong's here...
