Fellow bookworms with specific tastes, how do you get yourself to read Japanese novels?

Hey! So I've been stuck at this awkward stage for the past few months: I've read a few books in Japanese, slugged through them mostly, but I can't get myself to read anything else. It just feels like I can't find books that match my tastes, what I would actually read day-to-day — I'm a bookworm, I spend all my time reading books, whether it be in English or in my native language (so the linguistic barrier isn't the issue here).

Here's the question: how do you guys find actually good books? I like reading classics, but Japanese classics seem to focus on themes quite different from English classics (or at least, those with themes that'd interest me are probably written pre-1900s). I also like reading contemporary books, fantasy, SF, all kinds of stuff — but all I see among Japanese novels seems to revolve around depressing, real life themes with absolutely no scope for imagination.
