Rapid wartime carrier construction makes sense once losses and urgent demand dominate planning. Japan's prewar policy, however, should not imitate a navy with much greater industrial depth. More survivable peacetime carriers would preserve scarce hulls, trained crews, and air groups after damage. Because Japan could never replace carriers at the American rate, protection and damage resilience had greater strategic value than a design philosophy built around cheap, rapid replacement.

Japan needed survivable carriers, not an American production race
Because Japan could not replace carriers at American speed, its peacetime designs needed greater survivability.
