Study of Kaomoji 2

Why does japan have been able to evolve the Kaomoji (emoticon/smiley) ?

I think Japan have a lot of way to express the emotion don't use words.
That's the why the many Manga or cartoons have been developing expression only pictures don't use the words.
Most Japanese grown up to be seeing the manga, they can acquire the ability to express the expression with pictures.
What do you think?
