I left Australia in 89. The price of house in Sydney was boosted by Japanese for the first time in 88. There was retirement plan for Japanese in Queesland, I don't know what happened after I left. I did know 2 Japanese girls when I studied my English for the first 3 months when I was in English school. I have 2 Japanese men now with me in New York.
What you said about Japanese feeling about their victims are pretty the same as reported here in Chinese news media.
