"In fact, this chart is misleading, because almost none of the “Koreans” in Japan — the orange line on the graph — are actually Korean. They are what’s commonly known as zainichi — people of Korean descent, who were born in Japan and usually only speak Japanese, but who have Korean passports, because Japan does not have birthright citizenship." I venture to say that many if not most of the people on the chart were Japanese-born and raised. But they are NOT Japanese. That's almost a textbook case of Xenophobia. That's just me speaking as a Gaijin, of course.
