No Emperor address means the U.S. has either invaded, which would have killed at least 1,000,000 Japanese civilians, devastated half of Kyushu and a good third of Honshu (maybe more, depending on how long the IJA can hang on) or the U.S. decided on the blockade and burn campaign that was gaining traction in the summer of 1945, that would literally have called for starving and firebombing Japan until whatever was left of the government collapsed and surrendered unconditionally.What if there was no address by the Emperor, triggering the duty to obey him? With no impetus fromtheir leader to surrender, more resistance to the occupation would be feasible.
Mentions of food bring me to think: couldn't the resistance steal the delivered food when it is in Japan? I don't think any guerilla force in history was all that well fed, anyway.
Stealing the food would mean stealing it from heavily armed combat veterans with orders to shoot first and never bother to ask questions at any point in the future. Men who have had it drilled into them, possibly on Okinawa or in the Philippines, that "the &^%$% Japanese can't be trusted".
There is no scenario where the U.S. allows the Japanese to do anything but submit (same as the Allies did to Germany). If you submit and change your ways you get helped along with rebuilding the country. Resist and ever increasing portions of the country get wiped out. It is worth keeping in mind that this is the same U.S. Army that hounded the Native Americans across 2/3 of the continent within living memory and suppressed a pretty solid independence movement in the Philippines (and a Marine Corps that kept itself occupied during the interwar years defeating popular uprisings across Central America).
The U.S. was relatively gentle as a victor in 1945 because Germany and Japan submitted and accepted that they had been defeated. That allowed the U.S. to be the "shining light on the Hill" and install democracy while feeling really good about itself. Doesn't mean the U.S. couldn't have been very, very different, especially when the resisters were the same folks who attacked Pearl Harbor and committed the Bataan Death March.
