If they went on to do it to several other cities, demonstrating total control of the airspace and the ability to wipe any city of their choosing off the map overnight, and it was after years of losing battles... probably.
I’m not sure. Even then, knowing Japanese atrocities in all of Asia, it’s probably better to just keep fighting to the death as opposed to being subject to slavery, rape, or human experiments.
I’m sure a part of the reason the Japanese refused surrender was because their reflection in the mirror was not pretty.
