The trinity tests weren’t even close to Japan’s shore… yes, spies would’ve seen it, or heard about it, but regular army people, generals, etc. and the emperor would only know a second or third hand story.
Compare that to walking down the street and seeing a giant mushroom cloud at a safe but not so far distance, potentially with a large part of Japan’s navy gone in a blink (and maybe a bit of a tsunami as well). Let’s say this was timed such that the emperor himself would likely observe it. We can’t know for sure, and I concede that Japanese culture was very much “victory or death” at that time, but seeing it in person might, just might’ve changed some people’s mind, with a much smaller civilian death toll.
Doesn’t matter what the population thinks ultimately, it only matters what the leadership thinks, and the leadership would have gotten a full report on the destructive nature, and the ramifications of, from the Trinity test.
So blowing up another one off on the Tokyo Harbor wouldn’t have added anything to what the leadership already knew about their chances of winning the war.
