Me and my mum talked about this last time I visited my parents. Aparently the Japanese want to be more like European people, therefore they express it in they're biggest indistry: Animation (Anime) and Comics (Manga). This explains alot of the features used in anime. It's sort of the same as why so many european people want to get a tan. We came up with a much more indepth theory and all but I can't remember all the details......now its going to bug me for the rest of the day
