This bit is probably the hardest part. I have spoken to many people here in Japan who downplay, or justify, or say it is so long ago, or say that Japan has forgiven America, so naturally Korea and China must forgive Japan. "We've apologised, what more do they want? They are all crazy." ad infinitum. Or simply people that deny anything happened or think that I must hate Japan to even mention things like this.
Then you have politicians stirring things up and denying it etc.
What I think anyone really wants is simple plain humble acceptance of what happened. It seems the apology carries so much weight in Japan that that should just be the end of it, and everything should be forgotten.
Except that seems to be a purely uniquely Japanese way of looking at the world, and doesn't really translate to other cultures. Germany and the US don't sweep under the carpet the Atom bomb or the concentration camps, and likewise Japanese people should be taught about Nanking, the POWs, Unit 731 etc.
Just so that the average Japanese citizen doesn't come across on the world stage as wilfully ignorant or incredibly crass and insensitive. Ideally it could lead to more than this and improved relations in the area, but at the very least it would be wonderful for Japanese people to not unintentionally be saying really hurtful things to still living victims of these events.
I really wish they would teach that stuff in incredible detail. _Then_ maybe not talk about it, or sweep it under the carpet or whatever.
This national pride combined with ignorance is such a toxic combination.
Edit:
Just to add to this. What I think is particularly tragic, is how specifically considerate and compassionate the average Japanese person is. It is terrible that on average, such compassionate, considerate people can end up seeming so wilfully ignorant or even hateful. When I don't believe this to be the case.
