Agreed on them being poor design choices to begin with. And I get the impression it's not even a cultural thing. It's more that pervs have taken over in that culture. And Miyazaki has even gotten disheartened over it. So I know it's not just "oh all Japanese people are fine with gratuitous boobage for no reason, it's their culture". It may be becoming their culture, sadly. But its not everyone. And it's sad to define them that way
