Diana Literally anything from Haruki Murakami, especially Norvegian Wood or Kafka on the Shore, or After Dark. Keigo Higashino is also an excellent author. Miracles of the Namiya General Store is highly recomended, and his detective novels are also great. And I really enjoyed Before the Coffee Gets Cold by Toshikazu Kawaguchi too.
Jessie Sweet Bean Paste by Durian Sukegawa was really nice! You could also try Strange Weather in Tokyo by Hiromi Kawakami.
