I would go with an Eastern European, Japanese, or Scandinavian author, depending on what you're looking for. The Japanese (or the ones who I've had the pleasure of reading) tend to go for quirkier, more stylistic pieces while the Scandinavians go for very methodic, mythical, and, yes, difficult pieces. The Russians have writing like a thick, hearty soup: it's so full of plot, character, and detail. Not a light read. I would say that the Japanese have the most modern read, in a manner of speaking.
Here are some Scandinavian authors:
Other Eastern European:
Zbigniew Herbert (Polish)
These are kind of my opinion- Mitsugu Saotome is more a name that I know of as opposed to works that I've read, but you can give him a shot if you'd like. I hope that you find a good author and that you do well on your term paper. :)
