The bathhouse runs on a physics of absorption, not psychology.

When Chihiro eats the spirit food, her body doesn't symbolically forget—it *biochemically* transforms, and Yubaba doesn't steal names through magic words or contracts but through what gets metabolized.

The film's production design enforces this: every character who consumes stays. The bathhouse staff aren't brainwashed—they're fed, and Miyazaki gives this mechanism the same visual weight as gravity.

When Chihiro's parents stuff themselves with abandoned food, their bodies bloat and harden into literal pigs within minutes, not a curse but an inevitability—the way fermentation works. The film never cuts away from the grotesque expansion of their flesh, because this is not metaphorical consumption. The contract Yubaba enforces—where Chihiro surrenders her name by speaking it—only *works* because the food has already done the actual work, and the name-theft happens at the cellular level first while language just formalizes what digestion has already decided.

Haku remembers his true name only by *not eating* the river's food, which suggests that forgetting is the default state of the metabolized body, so staying yourself requires active refusal of every transaction. Japan in 1996 was watching its post-war economic miracle dissolve into the Lost Decade—what terrified wasn't losing money but losing the structure that money built, because Miyazaki understood that you don't conquer a culture through ideology but through feeding it, making consumption so normal, so pleasant, so automatic that the body naturalizes the foreign.
