Ikuhiko Hata

Ikuhiko Hata (秦 郁彦, Hata Ikuhiko, born 12 December 1932) is a Japanese historian. He earned his PhD at the University of Tokyo and has taught history at several universities. He is the author of a number of influential and well-received scholarly works, particularly on topics related to Japan's role in the Second Sino-Japanese War and World War II.

Hata is variously regarded as being a "conservative" historian or a "centrist". He has written extensively on such controversial subjects as the Nanjing Massacre and the comfort women. Fellow historian Edward Drea has called him "the doyen of Japanese military historians".
