> The bombs didnt end the war, a tape recorder did.
The senior commanders said they couldn't go against the emperor, so they would have to commit suicide to get out of the younger commanders way. That night they had a large gathering to ‘celebrate’ the death of the senior commanders. Too much was drunk and things didn't end till morning. They rushed to the Emperor's palace and surrounded - no radio address today.
What they didn't know was that it had previously been decided that the Emperor might not be able to get through reading such a document. It was decided to record the message and play it back over the radio (I don't know if the device was actually a ‘tape’ recorder, it may have used wire as many did back then).
When the radical commanders surrounding the palace heard the Emperor's voice over the radio, they knew they were sunk and committed suicide themselves. I always thought it was funny that people marveled at how good the Japaneses became at building consumer electronics. Hell, without them their country would have probably been bombed into the stone age - although it might have taken a little longer as we had already dropped the only two atomic bombs we had on them.

ICTOAN is referring to the recording of the Showa Emperor telling is subjects they must “endure the undendurable” by surrendering to the Allies. I’m not sure what the recording medium was, but it wasn’t a transcript - it was kept from the hands of the pro-war faction and broadcast on radio the following day (or so). It was the first time most of the populace had heard his voice.
ICTOAN is trying to sound knowing and cute all at once. The clear implication is that the Imperial Japanese gave up because their Emperor told them to, not because the Allies were bringing the war home to them; therefore, there was no need to drop the atomic bombs.
Arguments against this interpretation are legion, but are not needed. All we have to do is read the Showa Emperor’s speech. In it, he referred explicitly to the employment by the enemy (US & Allies) of “a new and most cruel bomb.”
The nuclear warheads detonated over Hiroshima and Nagasaki were all of that.
