I've yet to meet anyone that has studied in depth at school or remembers it. Most people if they remember or know about it at all, say they studied the "Nanking controversy" as a brief paragraph on one page.
In general people's responses are more of the downplaying or sweeping under the carpet type. I think this plays into worsening the relationship. No quiet contemplation, acceptance of what happened or pause for thought in general.
I've met the son of the rape of a Korean comfort woman forcibly brought to Japan, he grew up as Zainichi in Japan. He's lived a life as an outsider and has to hear people suggest that these things didn't happen. As if he shouldn't exist. So then instead he hears mention of financial reparations and lists of apologies. Which don't really count for much when it sounds like "I said sorry, why do you still care about this issue?"
I just wish people here were more compassionate.
