Japanese Literature discussion

I've been recently reading Mieko Kawakami and I love her works. I've been trying to find books like Heaven or Breast and Eggs. I've also been trying to expand my authors as I really only read from a few authors. Any recomendations? I'm open to different types of genres.

Well recently we have read Banana Yoshimoto’s The Premonition, and Aoyama’s What you are looking for is in the Library.
I also liked Before The Coffee Gets Cold, which the first of a series of 5 books. There were a range of thought on that on and you might scan the forum first.
