Considering everything Japan did during WW2, and how there are people still alive who lived through it, I’d say yeah, they still have some apologizing to do. Instead, Japan has been whitewashing their very active roll in the war and focusing on how they were victims - you must’ve missed the big brouhaha over “Barbenheimer” and Japanese folks insisting on apologies for it.
If they’re still insisting on people apologize to them, I’d say folks can still insist they own up to what they did.
