@ossobuco,
Few Japanese even of the relatively educated classes outside the Imperial Household Agency could figure out what it was that Emperor Showa SAID; the current emperor may have been similarly misunderstood. You don't know who Showa was, fine, but look up his speech when he was named just plain Hirohito and he addressed his nation, as was his ultimate duty; all other civilian and military (except for the very extreme nationalists who were prepared to see all of Japan vaporized into radioactive dust rather than surrender) shut up when he said:
"The war situation has developed not necessarily to our advantage". That was final, then, and that's final for now. The sun is rising now
