Haruki Murakami is one of the most popular and controversial of today's Japanese authors. His genre-defying, humorous and surreal works have sparked fierce debates in Japan over whether they are true "literature" or simple pop-fiction: Kenzaburō Ōe has been one of his harshest critics. Some of Murakami's best-known works include Norwegian Wood (1987) and The Wind-Up Bird Chronicle (1994–1995).
