Sorry for the late reply. I think the movie was based on the first book but not sure know how much changes the screenwriter made with it. For the drama, ep. 5, 9 and 10 were from Book 1 while ep. 8 and 11 were from Book 2. The rest were original stories from the director or with his co-writers. I will check out Matsuda's works someday. I even haven't seen Black Rain. He seems really intriguing. :)
