The Japanese were attempting to negotiate surrender with the “neutral” USSR prior to the nuclear bombs. https://en.m.wikipedia.org/wiki/Surrender_of_Japan The US wanted an unconditional surrender which included the destruction of the Japanese emperor, who at the time, was the head of the Japanese religion. To put this into perspective, consider the United States request similar to requesting the destruction of the Pope within the Vatican. Because of this, the Japanese were seeking better terms of surrender which did not involved the removal of their religious leader. What the Japanese did not know at the time was the USSR was not a neutral party, and they were secretly mobilizing their forces on mainland Asia due to an agreement Stalin made with FDR prior to the US entering the war in Europe.
The reality is, once Japan learned that the USSR was not neutral and they were going to be fighting the US and the USSR in a two front war, this is when the emperor forced Japan to surrender.
To put things into perspective, Hiroshima and Nagasaki, were sadly, just another two cities leveled by the US. The US were performing night carpet bombing on Japanese cities as soon as 1944. Many of these raids leveled several square km of urban areas. https://ww2db.com/battle_spec.php?battle_id=217. This is why people argue that Hiroshima and Nagasaki were probably not the catalyst to Japan’s surrender because the US have been leveling Japanese cities, killing hundreds of thousands of Japanese citizens, long before the two nuclear bombs were dropped. None of these raids caused Japan to surrender before.
