Hideaki Kase (加瀬 英明 Kase Hideaki?, born December 22, 1936) is a Japanese diplomatic critic known for promoting historical revisionism. His father, Toshikazu Kase, was a diplomat under Shigenori Tōgō who negotiated an end to the Pacific war.
Kase is the Chairman of Society for the Dissemination of Historical Fact. In an interview with BBC journalist Bethan Jinkinson, Kase said: "The majority of our people believe that Japan was forced into war by the United States. America was making unreasonable demands upon us. So we were fighting a war of national self-defence".
Also a member of Nippon Kaigi, Kase said about that openly revisionist lobby: "We are dedicated to our conservative cause. We are monarchists. We are for revising the constitution. We are for the glory of the nation".
Hideaki Kase has a history of promoting controversial movies that contest Japanese war crimes:
