What country, specifically?

If you're in the United States, the University of Wisconsin-Madison has a very strong Japanese program (Graduate, as well as Doctoral). I've also heard that San Francisco State University and the University of Colorado-Boulder have good graduate programs in Japanese, as well. I'm not a graduate student, but I've worked with several of the Japanese program faculty from UW-Madison, and they have been great to work with.
