Taranto as a proof of concept, not a Pearl Harbor blueprint

Japan had already been developing its own Pearl Harbor concepts; Taranto confirmed that a harbour carrier strike could work.

Question

What did the Imperial Japanese Navy take away from Taranto?

Short answer

It reinforced an existing Japanese concept by proving that a carrier strike against a fleet in harbour could work; it did not originate the Pearl Harbor plan.

Notes

Taranto did not directly create Japan's Pearl Harbor plan. Japanese planners were already exploring the problem and possessed doctrinal and technical work of their own. Taranto supplied real combat evidence that a carrier-launched harbour strike could succeed. That confirmation could strengthen an existing proposal without being its origin. The distinction keeps influence, proof, and independent development from collapsing into a single imitation story.
