Toshio Kuroda (黒田 俊雄, Kuroda Toshio, January 21, 1926 - January 26, 1993) was a Japanese academic, historian and university professor. A specialist in medieval Japanese history and in the history of Japanese thought,[1] he greatly influenced Japanese historiography with several innovative and controversial theories.[2] His ideas were the opposite of what mainstream academics at the time believed, and for this reason his name is often at the center of controversies.[2] His work has been called "seminal",[3] "epochal"[4] and "revolutionary".[2][5]
