@Northern You must be American, huh? You are that naive strictly in support of a nationalist narrative--you wouldn't believe such froth about any other country. It is of course incredibly rare for anyone ever to get sanctioned because they did atrocities. It is very common for atrocities or human rights violations to be
referred to when sanctions are put in place, but almost always the sanctioning entities are guilty of exactly the same sort of thing or are best friends with others who are, so you can tell pretty easily that the question is not what atrocities are being done, but who is allied with whom.
Hence for instance today, the United States has sanctions on Iran for doing far less to promote terrorism and war and being far less undemocratic than their best buddies Saudi Arabia or the United Arab Emirates, and sanctions on Venezuela for being far less undemocratic than and violating human rights far less than their best buddies in the neighbourhood such as Honduras, Colombia, Brazil etc. This is not to say that Iran isn't guilty of anything, but that it doesn't matter whether they are or not for sanctions purposes because that's not in any way why they are being sanctioned. Nor was it why Japan was sanctioned. Japan did horrible things, but if it weren't interfering with various colonial powers' interests they would not have cared. And it certainly was not at all different from the many massacres those colonial powers had committed and continued to commit both in that area, in Africa, and basically anywhere they could get away with it. The victims were only relevant if someone outside the club was doing it, or in the case of Germany if they were bringing the techniques home to Europe instead of keeping them in places like the Belgian Congo where the mass death was easier to ignore.
And no, I have nothing to do with ultra-right propaganda whether Japanese or of any other sort. To the contrary, my position is far to the left of any Japanese or American government of any time period to date.
As to Indonesia and the Philippines, not to mention Korea and Vietnam, it's true that the US was gradually giving up on direct colonial rule; it was already over 30 years since their massive massacres in the Philippines. But they were consistently dominant in regional politics, making sure that local rulers backed them economically or geopolitically--generally, the more key they were geopolitically, the longer leash they were given economically. They installed a dictatorship in South Korea; it eventually went democratic, but that sure wasn't the US' intention. When local politics threatened to behave independently, as in the case of Sukarno in the Indonesia, the US would back dictators like Suharto in Indonesia, Ferdinand Marcos in the Philippines, or whatever stooge they could scrape up on any given day in Vietnam until they were kicked out.
And of course the Americans never apologize for any heinous act they perform. They're very explicit about this. George Herbert Walker Bush, on the subject of an American warship shooting down an Iranian airliner (and the guy responsible getting decorated): “I will never apologize for the United States of America, ever. I don’t care what the facts are.” And this has proved the general attitude, whether it's about retail atrocities on the ground, or torture, or nuclear bombings--the US never apologizes. So it's kind of amusing to see an American complaining about the Japanese behaving exactly the same.
