From what I've read, Japan never had anywhere near the industrial capability to pull any of that off. Even landing troops and maintaining a garrison at all on Midway and the Hawaiian islands would stretch them to the limit - they arguably already didn't have the troops to spare to do that along with their other commitments in their Greater East Asian Co-Prosperity Sphere plan. Taking Hawaii at all is already outlandish, no chance that if they found a way to pull that off, they'd be able to supply it heavily enough to make it an active seaport, patrol the waters to the east aggressively, or carry out attacks against the US West Coast and their land-based defenses at a high enough tempo to impede shipbuilding there. Similarly, maintaining enough spies and subs to track ship sorties and ambushing them at the Panama Canal isn't in the cards for them. WWII is ultimately a logistics war. Individual battles don't really matter that much, whoever makes the most stuff will win eventually somehow, and whoever is on the other side from them will lose. Japan was way too far behind on industrial capacity to have a chance. Maybe if they managed to pull off their Co-Prosperity Sphere plan without any interference and make the most of it, they'd have the capacity in 40 years. But that's doubtful too, since everyone else in their so-called Co-Prosperity Sphere hated their guts due to horrible occupation practices on the part of the IJA.
