Fortunately the "Japanification" of Taiwan got a late start, or else many people in Taiwan today might not know their ancestral surnames. Surnames and genetics Perhaps there are those who wonder what difference it can make what your ancestral hsing-shih was.
幸而皇民化改姓的運動實行得晚，否則今天的台灣人，恐怕也有很多人不知道自己的祖先姓什麼了。
