Like maybe, idk, slapping the wartime flag of an Axis Power on its clan logo.
Actually, the Clan Icon is the Japanese naval jack, still in use today by the Japanese Maritime Self-Defense Force (and also very similar to the insignias of the Japanese Self-Defense Forces and the Japanese Ground Self-Defense Force). It's not the Japanese war flag. Its only association, historically, has been with the naval operations of Japan. If you want to talk about atrocities, virtually every flag of a geopolitically significant country is tainted- the American by Operation Condor and the War in Iraq, the Indian by Operation Polo and Operation Blue Star, the Russian by the illegal invasion of Ukraine and the harassment of Georgia and historically many other countries, the German by WWI/WWII/East Germany's horribly oppressive governance, the Korean by USAMGIK and various dictatorships, the Salvadorian by the Football War, the Mexican by Santa Anna and imperialism, the French by Napoleon and massive settler-colonialism, the Belgian by brutal conditions in Leopold's Congo, the Turkish by the Armenian Genocide, the Cambodian by the Khmer Rouge, the Somalian by piracy, civil war, and ethnic cleansing, the Rwandan by ethnic cleansing, etc.
