why do Japanese people love to point this out? I'm assuming you are Japanese given your peculiar style of broken English grammar unique to Japanese and your overall negative past comments on HN towards China and Korea in particular. It's like saying "Michael Jackson. It is not american but african." (in your own words). There's always this undertone of contempt and jealousy from some Japanese users whenever anything Korean is mentioned. Just take a look at youtube comments. Some Japanese folks are now posting under terribly inaccurate American names or worse pretending to be Korean and posting really weird shit.

Zainichi Koreans have suffered racism and long period of oppression. They are far removed from Korean culture, it's the fact that Japan doesn't give citizenship to what it considers impure blood yet at the same time, if you are half Japanese, you are eligible. What does this say about Japanese society? There's a deep rooted institutional level of racism. I'm sure those that have lived in Japan will know of this ceiling.

What's remarkable about Masayoshi is that despite the odds being against him, he pulled so far ahead of what an average Japanese could achieve. One of his earliest childhood adversity is some Japanese kid threw a rock at him for being Korean yet with no repercussions for such hate crimes.

Looking at Japan, celebrities and businessman of Korean descent but nowhere are they considered to be Korean in Korea unless they speak the language and appear on Korean variety shows (like Korean-Japanese UFC fighter and Judo master Yoshihiro Akiyama), and they seem to be treated like shit in Japan. It's no surprise that even Yakuza membership have lot of Koreans given the poor level of opportunities available to them in Japan.
