Internationally popular novelist Haruki Murakami is working on an extremely lengthy novel. But he appears to cherish every moment.

"Every day, I am sitting at my desk for five to six hours. I have been writing the novel for about one year and two months now," he said in a rare interview.

Last fall, he published "What I Talk About When I Talk About Running," a book about his experience as a marathon runner and a triathlete. It is also about the relationship between running and writing.
