On a related note, you my friend, as well as anyone else who enjoys history, might enjoy an author by the name of Harry Turtledove who specializes in writing alternative historical fiction; i.e. what if the South won the Civil War? He wrote a couple of pretty good books about what a successful Japanese invasion/occupation of the Hawaiian Islands after Pearl Harbor might have looked like.
I'm familiar with that particular author and the genre as a whole. I try not to wade too deeply into it. Counterfactuals are fun but shouldn't be the main foundation of historical scholarship.
I'm skeptical of Japan invading even on December 7. Put simply --
-- A carrier raid is different than bring a slow-moving invasion force. A carrier force and its escorts can make military speeds; an invasion force has to crawl along at the speed of civilian cargo ships. This greatly increases the risk of the U.S. tripping over the Japanese fleet and preparing accordingly.
No massive surprise on the morning of December 7th and that battle goes
very differently. The U.S. had ample AAA assets (on land and on the ships in port) at Pearl Harbor as well as land-based aircraft (either USAAC or carrier airwings that could fly off runways in a pinch). The second Pearl Harbor raid had some terrifying loss rates for Japanese aircraft, and that was after only a few hours of chaotic response.
Imagine coming into an opponent who knows you're coming as is pissed about it instead.
-- Dedicating infantry and shipping assets towards Oahu means compromising Japan's offensives in the South Pacific towards needed natural resources and/or securing the supply lanes protecting the route from what is now Indonesia back to the Home Islands. Would you really invade Hawaii at the expense of either the Philippines or Malaysia -- the upshot of this being you now have a British or American redoubt on the flank of the shipping lanes that you need to secure to keep your petroleum supply safe?
It just doesn't work. Too risky, gains you little, and costs you everything the war was about for Japan.
