Kō Bun'yū (Japanese: 黄文雄; born 1938), also known as Huang Wenxiong (Chinese: 黃文雄; pinyin: Huáng Wénxióng; Pe̍h-ōe-jī: N̂g Bûn-hiông), is a controversial Taiwanese author, now resident in Japan, who is well known for his staunch anti-Mainland Chinese stance and for penning a number of highly controversial books about Chinese, Japanese and Korean history and culture. Kō was a visiting professor at Takushoku University. His works often assert that Taiwan and Korea owe their present-day successes, and much of their culture, to Japan.
