Novelist Haruki Murakami announced Sunday he will donate original manuscripts of his works and other materials to Waseda University, from which he graduated in 1975.

The donation "is a very important thing for me, so I thought I should explain clearly" by holding a news conference, said Murakami, 69. "I don't have any children, and it would cause trouble for me if those materials became scattered or lost."

It was his first news conference in Japan in 37 years.
