A Japanese invasion of Hawaii required a substantial investment in seaborne logistics. Carrier night-fighting doctrine or building the Yamato class as carriers would not by themselves provide the means to land and sustain an army. The proposed scenario depends on a sizable landing force arriving with the surprise attack on Pearl Harbor. Even with that support, successfully contesting the island and actually capturing it remain different outcomes.
