I am probably the only one here who gives a crap but after 3 days work I thought I would share any way 
Kaomoji are the emoticons made with mostly UTF8 and Shift-JIS characters ヽ(`д´)ノ Mac users have a dictionary system that can make typing them automated through the transliteration system but it will require using the Koteri(Japanese) input system so if you don't know any Japanese this may be difficult at first and no you don't need a Japanese keyboard to do this.
I am including the dictionary I created to make using 1,103 kaomoji easier. You can get it here Kaomoji Dictionary the dictionary and a pdf list of kaomoji are inside the zip file.
To use it,
1 - Setup JP input
[System Preferences...]>[international]>[input menu]... check [あ] Koteri and atleast [あ]hiragana you can have the others but MUST have that one
2, Put the dictionary file from the zip folder into the "~/Library/Dictionaries" folder
3 - Double click the かおもじ dictionary and close the resulting window.
4 - Open the book in Koteri preferences
input menu > Koteri Preferences > [Dictionary] tab open かおもじ book.
Now when you type certain japanese words in hiragana and you hit space some faces will show up. With the dictionary I included the list of 1,103 kaomoji with what you type first and the output second. To use it type the characters in the first column (using hiragana) and hit space, the faces will be in the transliteration menu that pops up.
you can test by setting your input to hiragana and typing [ かおもじ ] "kaomoji" and press space then scroll down until you see a face you like and hit enter.ヽ(´―`)ノ
