They’ve issued a bunch of specific apologies specifically regarding the “comfort women”, beginning in 1992 and then frequently thereafter. At various times they have apologized several times per year.

The apologies are listed here: https://en.m.wikipedia.org/wiki/List_of_war_apology_statemen..., culminating in a 2015 apology that was agreed to by South Korea to “finally and irrevocably resolve the issue”

And amazingly still the notion that they won’t apologize for it is commonplace.

From the above source I linked:

>Neither the U.S. government nor the state of California has acknowledged that the California Indian catastrophe fits the two-part legal definition of genocide set forth by the United Nations Genocide Convention in 1948

Finally, I don't see why Japan is singled out. The rape of Berlin could have been worse. Millions of Cambodian Viets were pick axed to death in the Killing Fields. Norway kills far more whales, especially on per capita basis. We still throw people in prison for smoking plants and are quiet about our police state. The Japanese were utterly bombed like almost no other time and place in humanity, and the only leadership from that era which survived did so by the US. And I don't see any people broadcasting their views about social justice for women going to Southeast Asia where Western money pours in to sexually exploit women. I think we live in an era with its own virtue politics, not an era of actual virtue.
