It& #39;s hard to believe that many people in Japan even knew Hana Kimura was mixed-race, let alone she was part Indonesian. It& #39;d be too quick to say that the hate she received is a direct manifestation of racism/colorism. A factor, indeed. But we should look more carefully.
As of now, a Twitter search of "花 インドネシア" shows nothing but "was she half Indonesian?" It& #39;s imperative that we take into account the possibility of racism playing a role in a wrong done to a racial/ethnic minority or mixed-race individual, but we should not rush.
