What is the author's style in Norwegian Wood by Haruki Murakami?

Language is a difficulty for Naoko. In Murakami's novel, language symbolizes communication, life, and being part of humanity. Naoko can never find the words to say what she means, and she cannot find the words to write letters. Language escapes her. It is a link between the world of her mind and the physical world around her, and that link goes missing for her. The lack of language is symptomatic and symbolic of her isolation. Without it, she is lost.
