Let's use Japanese emotictions!!
キタ―――――――（・∀・）―――――――！！
⊂二二二（　＾ω＾）二⊃ﾌﾞｰﾝ

（≧▽≦）, (´・ω・), (つ∀｀)　etc...


We can copy/paste from web sites, searched "顔文字" in google.

Or we can find some examples in Wikipedia
http://ja.wikipedia.org/wiki/%E9%A1%94%E6%96%87%E5%AD%97

Another way to put emotictions, we can install 顔文字辞典(EmotictionDictionary).
It works in your conversion phase of typing Japanese.

But if you don't want to install software,
you can use the examples from these texts.
