Most of Haruki Murakami's works use first-person narrative in the tradition of the Japanese I Novel. He states that because family plays a significant role in traditional Japanese literature, any main character who is independent becomes a man who values freedom and solitude over intimacy. Also notable is Murakami's unique humor, as seen in his 2000 short story collection, "After the Quake". In the story "Superfrog Saves Tokyo", the protagonist is confronted with a 6-foot tall frog that talks about the destruction of Tokyo over a cup of tea. In spite of the story's sober tone, Murakami feels the reader should be entertained once the seriousness of a subject has been broached. Another notable feature of Murakami's stories are the comments that come from the main characters as to how strange the story presents itself. Murakami explains that his characters experience what he experiences as he writes, which could be compared to a movie set where the walls and props are all fake.
