I don't think I answered the question. Seems that a lot of the younger Japanese guys aren't "cute" to me because their looks are just too feminine looking, even though, I found Tatsuya Fujiwara cute in Deathnote, but mainly because of how he played the role. Anywho, seems I'm more attracted to older, in some cases, distinguished looking, guys, so my pick is Owatari Ryo of Do As Infinity. I know some, by your standards, he's old (late 30s), but I always found him to be incredibly cute...'cept for when he debuted and had that blonde hair.
