Chihiro: Listen, Haku. I don’t remember it, but my mom told me… Once, when I was little, I fell into a river. She said they’d drained it and built things on top. But I’ve just remembered. The river was called… It’s name was the Kohaku River. Your real name is Kohaku!
Haku: Chihiro, thank you! My real name is Nigihayami Kohaku Nushi.

Chihiro: For some reason, I can remember Haku… from a long time ago… but I thought I never met him before!
Zeniba: Oh, that’s a wonderful place to start! Once you meet someone, you never really forget them.

No-Face greatly resembles a silkworm, an important animal in Japanese culture. Silkworms have markings that look like facial features, with their mouths are below these markings, like No-Face. Both eat constantly and grow rapidly and No-Face ends up spinning silk later in the film.

Zeniba: The protective seal on my gold charm is gone!
Chihiro: You mean that little black slug? I think I killed in when I stepped on it…
Zeniba: HA HA HA! My sister put that there so she could control Haku… and you killed it! HA HA HA! But it’s strange… only love can remove a seal.
