Japanese people often fail to understand why neighbouring countries harbour a grudge over events that happened in the 1930s and 40s. The reason, in many cases, is that they barely learned any 20th Century history. I myself only got a full picture when I left Japan and went to school in Australia.
It causes endless frustration to the foreigners living here that so few Japanese people seem to GET why their Asian neighbours are annoyed and haven't forgotten about the war.
It's amazing how few young people there know much about it, and how much power the small group of nationalists seem to have over politicians and public opinion. (in a country where most people are very generous and not at all extremist).
The nationalist view seems to win by being the only view offered.
It is also intriguing to see the differences in how the WW2 issue has been handled in Japan and Germany. And the totally opposite results when it comes to education, politics and relationships with neighbours.
It is a shame. Young people in Japan of course bear no responsibility for what was done before they were born, but because they don't learn about it they end up either ignorant or defending it.
