The Emperor still had a lot of power with the public
And how much power exactly did the public in Japan have? Even the Diet at that time was controlled by the military.
Even before the war, every single Prime Minister was either an Admiral, or General. And the Prime Minister ran the country. They controlled the Diet and Emperor both. Nothing came to a vote in the Riet without the approval of the Prime Minister, and the Emperor had no power.
And trust me, I lived in Japan. I am not talking about what you are calling "Time/Life", I have been studying the Showa era and before for well over 40 years now. Good luck even finding many books that even talk about the Taisei Yokusankai, let alone most of the other things I commonly discuss in regards to that era.
And "cult tradition", I assume you are trying to talk about Shinto? Yes, the Emperor was a "Living God". He was arahitogami, the living descendent of the Sun Goddess Amaterasu. And as such, he lived on a higher plane than "mere mortals", and it was his job not to run the country, but to be the intermediary between the people and their deity.
Until 1 January 1946, when he gave the Ningen-sengen, or "Humanity Declaration". Where Emperor Showa formally renounced his divinity.
And notice throughout this debate over 170 pages long, and every other the things I say. For example, how I never call the former Emperor "Hirohito". I always address him in the Japanese tradition, after his reign name of Showa, or "Enlightened Peace". This is the Japanese custom, former Emperors are never addressed by their name after death, but their reign name. And how I almost constantly drop very specific references of Japanese culture and organizations.
Ningen-sengen, Taisei Yokusankai, the Japanese response of Mokusatsu to the Potsdam Declaration. Tell me, exactly what "Time'/Life" books actually discuss things like that? You are simply trying to be dismissive because you do not like the message. But trying to insult me does not make what I am saying any less accurate.
Hell, how was the Emperor even going to get the people on his side? All communication out from the Palace was only by messages to the media through the Prime Minister. Hell, until the 15 August 1945 broadcast of the Gyokuon-hōsō or "Jewel Voice Broadcast", the Emperor never even spoke on the radio! Nobody in Japan actually knew what he sounded like. And he was so far removed from the population of his own country that the language he spoke in was archaic, and they actually had to have a translator come on immediately to repeat it into "Common Japanese".
Yet, you think he had "a lot of power with the public"? That is a complete joke, he could barely speak with the "public", he spoke a form of "Court Japanese" that was hundreds of years old, because of the isolation of the Emperors for hundreds of years.
