Murakami is one of the best writers alive today. And he happens to be Japanese. A major book of his just came out, titled IQ84. I'm not far enough into it to know where it stands among his other works, but I wager it'll be up there. Anyone looking for their next book to read should look no further.
On a side note, I'm also reading the just-translated manga Drops of God. It's an educational manga about wine. Also good.
