As a person of Hong Kong-Chinese descent, I can sympathize. Although the trillions of dollars in trade between Japan and China and South Korea tells me that we should put the past behind us to some extent.
However, the lack of responsibility that Japan, as a government, nation and culture, bears about WW2 really prevents me from fully enjoying many aspects of their culture, especially those that are often discussed on these boards. It makes me acutely aware of the Japanese science fiction and anime that has a WW2-Japan-as-victim theme (Godzilla, Grave of the Fireflies, Akira). I love the Macross saga, but I am aware that it is maybe one step away from being a hate crime.
