It's not just a lack of education, it's outright propaganda.
Japan had no intent to surrender regardless of what the US did, They're long history of nationalist ideology and the concept known as bushido, which teaches *honor unto death ensured that.
In the months leading up to the bombing Tojo and the military establishment that controlled the Japanese government refused the US' demands for an unconditional surrender multiple times.
This was largely because the terms included a restructuring of the government and the removal of the emperor who was essentially considered divine and still is to some extent. The military establishment also opposed it because the US planned to, and ultimately did completely dissolve Japan's military power.
Instead, they were preoccupied with rather or not the Soviet union would continue its neutrality pact with Japan. They knew they were in a war that they couldn't win but against the US and the Red Army, they would face a threat on a whole different level.
On the same day the second bomb was dropped on Nagasaki, Japan surrendered. Ironically, while they did agree to an unconditional surrender, the Americans never removed the emperor.
Following the American's post-surrender invasion of Japan, the allied forces convened the International Military Tribunal for the Far East was held, also known as the Tokyo War Crimes Trial, were held. A number of ranking military officials and political leaders were convicted and hung. Several others were sentenced to life imprisonment or lesser sentences.
These "trials" have since been the target of strong criticism by the International Criminal Court(ITC) as being "one-sided, victor's justice" rather than actual due process.
Emperor Hirohito and other members of the royal family were exonerated of any alleged crimes and Hirohito's overall role in the war is actually widely debated among scholars to this day.
Getting back to the concept of Bushido, even after Japan surrendered officially, the Japanese continued to fight until Hirohito himself declared that the Japanese had officially surrendered several days later. This is a testament to the divine status of the emperor at the time.
In Germany, to the best of my knowledge it is a crime to publicly deny the holocaust.
In Japan, you actually have a fair number of people that deny most of Japan's "war crimes" ever happened, Including the well documented Nanking massacre or rape of Nanking.
In that sense, Japan is a lot like the US. We blatantly deny, and most of the population believes that we have never done anything wrong.
Since the birth of US capitalistic imperialism in the 1890s, the shit we've done and the number of people we've brutally massacred makes Hitler look like a saint and the holocaust look like nothing.
We knowingly harbored and employed several ranking Nazi scientists and engineers as part of the CIA's Operation Paperclip.
This is the shit they don't tell you in school. American history is a very, very, dark thing and until we accept the fact that were no better than any
