In the East, China and Korea (not sure about other places that suffered under the Imperial Japan regime) will focus on that and overlook the West front. That's why you see some funky things like use of WW2 German fashion (which is cool looking if we ignore the meaning behind it and it was on purpose to look cool as the Nazi appropriated lot of cool symbols to legitimize their power). Japan will overlook WW2 completely as well unlike Germany and Italy. Even in their pop culture, you rarely see the whole colonial period being touched upon. It's either the final moments of WW2 (like the bombing of Tokyo or the nuclear bombing of Hiroshima and Nagasaki) or parody.
Lot of weebos also repeat propaganda from Japanese far right as fact. The image of 80s to today's Japan is very contrasting to the militaristic Japan.
People bring up some of the bad stuff, but they still ignore more specific stuff like mass displacement of people, eugenic experiments, looting, and use of chemical warfare Japanese committed during their colonial era. Maybe the bulk of the atrocities were during WW2, but Japanese atrocities started way before WW2 and joining Axis Power. They looted the shit of Korea during the 30s and it was largely ignored at the time because after all colonialism was OK for the Allies as they did loot their possessions as well. It is still ignored as bringing up the subject of returning looted artifacts will be touching to lot of countries.
Another example of overlooking things is Turkey in case of Armenian genocide. People forget that Assyrians and other peoples also suffered genocide as well and they overlook the role of Kurds in that.
Even today we focus way too much on some stuff like Uyghurs and Palestine and we should, but we overlook Yemen and Tigray (where lot of people died, I mean WW level of numbers). Before Palestine conflict rose up, Myanmar was the focus, but it rapidly phased away.
If you study WW2 in great details we overlook way too much stuff like the roles of other nations in the war. Whatever you studied about WW2, it was just a scratch.
In general, we overlook lot of stuff in history out of self-interest and convenience or lack of it. People bring up USA role in killing and colonizing Native Americans, but it seems to me Canadians, Australians, and so on get a pass on that regard more often than it should. With the recent news about Canadian residential schools, more people outside that region will be more aware of that.
I don't think it is quite forgotten. I think people interested in history are more aware nowadays than before. The problem is the general population view on history is rather just very footnote-ish save a handful of subjects. The world is highly connected (even since ancient times), but the way we learn history is very disjointed and disconnected.
i guess at least he’s not shy to make connections behind the scene
