I refuse to use the cultural relativism of statements like "it's their culture...they're different...they have to find their own way"
This is chauvinism. The same mentality that led Japan down the road of fascism and militarism and into the well-documented events of the early 20th century.
Germany acknowledged what they did, and not just with platitudes (which Japan seems to excel at) but with financial compensation and what can only be seen as sincere motivation.
Japan? Their leaders visit Yasukuni Shrine and whine about being victimized.
