They could have dropped the bombs on the coast or a non populated area as a warning, and act if they didn’t surrender though. That’s a demonstration, dropping it in a city/town was not, that was a masacre.
They dropped the first one on a city and that didn’t get the point across, what would bombing a beach do?
that would be very expensive (in terms of materiel) demonstration that, considering 1. japanese mindset at the time and 2. the fact that nobody has been nuked to date, would be probably not effective at all. Today, this works because everyone and their grandma knows that nukes exist and they do work
Dude they dropped a bomb on a city, and they completely ignored it. In fact, there was an attempted coup by several the generals to kill the other generals who wanted to sue for peace. These were really militant military men.
The Kyūjō incident (宮城事件, Kyūjō Jiken) was an attempted military coup d’état in the Empire of Japan at the end of the Second World War. It happened on the night of 14–15 August 1945, just before the announcement of Japan’s surrender to the Allies. The coup was attempted by the Staff Office of the Ministry of War of Japan and many from the Imperial Guard to stop the move to surrender.
They attempted to place Emperor Hirohito under house arrest, using the 2nd Brigade Imperial Guard Infantry.

So when people argue that the Japanese were willing to surrender without a bomb or a major military conflict, they are completely ignorant about the trajectory of what was actually happening. We’re lucky that we didn’t have to drop five nukes AND invade. And don’t forget, the Russians were going to invade as well.
