Which was why Tojo tried to kill Hirohito before he could make that broadcast.
Was it ever proven that Tojo was behind a plot?
Wouldn’t surprise me, those Bushido loving military personnel were crazy enough for anything.
I know some officers wanted to take Hirohito prisoner and pressure him into urging a guerrilla war.
Some junior officers tried to break into the building where the recording was kept and steal it.
Crazy things happen when a war is winding down.
