I believe the mincho font (pretty much the de facto standard of modern kanji) does have italics. They're not used all that often or to the same effect as in English though. Others have also pointed out the dots which are quite common in formally printed materials. In emails and such, I see people use the 「」 quotation bracings as emphasis from time to time.
