Am I going too far from the topic "Hot Asian guys"? This is absolutely not. The sexy hot guy I would like to introduce here is 100% Japanese, and he is type of Japanese men sometime we meet (in some pictures he looks quite Caucasian, but I think you will change your mind if you look at them again).
Ken Hirai is more than just a handsome and manly face, he is top R&B and pop singer in Japan. He has wonderful voice that could shows "full spectrum of soul". If you need a proof, there is one of his video clips on this post.
And here is his video clip - Elegy. Very simple, just him, singing, topless but beautiful with very impressive emotions showing. Kinda sexy!
