Interesting that you mention Thomas Mann, since the protagonist, Toru, is studying Western literature, and during part of the novel he's carrying Mann's Magic Mountain around to read. According to some reviewers, Murakami deliberately imitated one of the themes in that book since Norwegian Wood also features characters withdrawing into their own world within a sanitorium.

I may check out Doktor Faustus, and the Master of Go also sounds interesting, thanks.
