長谷川 毅
United States Japan 1941– ○ Active scholar

A historian who recast the international history of Japan's surrender

Japan's surrender in August 1945 cannot be explained by the atomic bomb alone.

Tsuyoshi Hasegawa is a Japanese-American historian of modern Russian and Soviet history, the Cold War, and Russo-Japanese relations. His work ranges across the Russian Revolution, Soviet-Japanese relations, and the international history of the Pacific War's end, linking diplomacy to social and political change. His major book, Racing the Enemy, reopened debate over Japan's surrender by arguing that the Soviet declaration of war and invasion in August 1945, not the atomic bombings alone, decisively altered Japan's strategic options.
