Let's have Japan make survivability a design/doctrinal priority for their carrier forces. The IJN knows they will face the USN carriers in larger and more replaceable numbers, and thus needs IJN carriers that can take punishment and either keep on fighting (i.e. operating aircraft) or survive to be repaired and fight again.
The focus on survivability is based on damage mitigation and control. Everyone onboard is trained in damage control. The ships and air ops are designed to mitigate damage. Design audits and testing of theories (such as Taiho's fixed avgas cells in elevator wells) are undertaken.
