First thought?
How forthcoming male Japanese characters are. They always tend to have this really deep, sometimes even booming voice. Emphasis mattering a lot more in Japanese than it does in English, a lot of the "auditory structures" you hear from a foreigner's perspective sound cartoonish.
Like, a North-American man who's angry might not shout. He might not even raise his voice. His anger's going to carry in his gestures and posture, and in the sentence stress patterns he uses. In Japan, angry men seem like they're obligated by structures in the language to start sounding like they're out of their minds with sheer rage.
I'm assuming it's only a question of perspective, of course.
The same goes for incredulity. We'll just go "What?!" and not really try to drag it out. They'll go "NAAAAAANIIIII?!" as if the longer it's stretched, the more appropriately incredulous they look.
