What is Kanji ???

*sigh* Kanji is the chinese/japanese writing system. In Japanese they combine kanji and katakana or hiragana in their writing. No, konnichiwa cannot be translated to kanji, it can only be as hiragana or katakana. In chinese it may be different, but I have yet to study chinese. ^_~
