I haven´t seen a single account of the likes. Japanese society is no russian or westerner society, vulnerable to the "stab in the back" sindrome of leftist vermin. The loyalty to the Emperor was not only political but spiritual and there were infinite accounts of this while the landings and invasions as places such as Iwo Jima and Okinawa, were even female civilians hurled themselves from cliffs with their newborn childs before being taken prisioners from the US Marines.Riots and strikes had broken out and Hirohito was looking about as secure as the czar and the kaiser in 1917 and 1918 respectively.
With popular revolt brewing, it may have been felt that a tame population would be easier to handle than one which had just hauled Hirohito out of his throne.
Don´t make the common mistake to equate the Kaiser stance with that of Hirohito, which is why McArthur´s behaivor during his rule in Japan was so brilliantly done.
Japan would have fight an invasion. Millions would have perished. And, on second thought, the only ones that would have benefit from this would have been Joe the Butcher and the soviets: whilst US spill blood in Japan they could have easily launch their must desired Red Storm over Europe.
