These two emoticons demonstrate an interesting cultural difference.
The West reads from left to right, and looks at the mouth for the best indication of emotion.
Japan judges a person’s emotional state more from the eyes. This is possibly due to their culture of hiding visible emotions, as the mouth can be more easily controlled than the eyes.
According to a street survey conducted by a Japanese TV station, the Japanese emoticon (or kaomoji) for happiness (^ o ^) is more likely to be perceived by non-Japanese as an expression of surprise or dismay, due to the rounded mouth.
Apparently Brazil is quite enjoying adding eyebrows too.

What a wonderful world the Internet is! :3
