1Q84 Book 1: April - June by Haruki Murakami

Tengo couldn't sleep. Fuka-Eri was in his bed, wearing his pajamas, sound asleep. Tengo had made simple preparations for sleeping on the couch (no great imposition, since he often napped there), but he had felt not the slightest bit sleepy when he lay down, so he was writing his long novel at the kitchen table. The word processor was in the bedroom; he was using a ballpoint pen on a writing pad. This, too, was no great imposition. The word processor was undeniably more convenient for writing speed and for saving documents, but he loved the classic act of writing characters by hand on paper.

Writing fiction at night was rather rare for Tengo. He enjoyed working when it was light outside and people were walking around. Sometimes, when he was writing at night while everything was hushed and wrapped in darkness, the style he produced would be a little too heavy, and he would have to rewrite the whole passage in the light of day. Rather than go to that trouble, it was better to write in daylight from the outset.
