Toru, the protagonist of The Wind-Up Bird Chronicle, exhibits traits of a postmodern hero but does not fully fit the role. He has flaws like paranoia and infidelity, feels isolated, and wants to be a hero but often fails. While he has some gritty qualities, applying a Western literary structure may not fully capture the novel's intentions, as it draws connections between Japan's history and culture in a way that requires an understanding of those Eastern influences.
