There's a great deal of variation. At St. Maur's International, a English-based Catholic School in Yokohama, the Japanese occupation of Nanking was (and I assume still is) taught in all of its gory detail (at least, to what is considered an "acceptable" standard for 5th Grade sensibilities).
Of course, that's going to be an exception--it's a school for foreign students. In Japanese public stories, it's an entirely different story. Which is bad, and should be corrected.
American history textbooks have their own degree of revisionism--for example, you'll never here of manifest destiny described with the word "genocide"--which it was (millions of people died over the course of decades). It just doesn't happen. You'll hear about the spread of disease, Indian-Federal warfare, massacre of buffalo. But genocide? Not on the Dept. of Education's watch--the book just wouldn't be approved for public use.
Certain other events, like the Firebombing of Dresden, or Operation Phoenix (campaign of terror tactics, like rape and murder, against Vietnamese civilians to weaken the NVA) aren't necessarily mentioned in text books....period.
It's far from perfect. In the case of Germans, specifically relating to the extermination of Jews, better measures have been taken--the German state has even erected memorials to the Holocaust, something you'll never see America or Japan or Britain do of their own violition.
Though from what I've heard, Germans don't really talk too much about the 11 million Soviet civilian deaths at the hands of the German Army during WWII. It was taught in East German schools (guess why), but it's become more or less a footnote--despite being almost twice the number of Jews murdered.
It might come from the fact that the Germans of the time saw the Soviets the same way the Japanese saw the people they subjugated (though unlike the Chinese and Koreans, the different nationalities of the USSR got their revenge--resulting in more forgotten war crimes).
In short, don't depend on public school textbooks to know history. Or private school ones, for that matter.
