With or Without Facial Expressions

Shy people show less facial expression.

Even in USA, many young kids are shy and they show less.

We Japanese are very very shy even when we grow up.
Many Japanese feel safe only in their closed small circle.

Maybe that’s why they don’t show emotions or feelings on their face.
Maybe they are like lots of superheroes who don’t show their true feelings. 

On the other hand,  too much facial expressions are made on TV shows and TV dramas.

I think this phenomena originates from their shyness as well.  They want to hide their true feelings so much that they tend to fake their emotions, which leads to those too-much-bad-acting expressions.
