Akira Iriye, a distinguished Japanese-American historian renowned for his work on diplomatic history, international relations, and transnational history, passed away on January 27, 2026, at the age of 91. He died at a retirement home near Philadelphia, Pennsylvania. Iriye's academic career spanned several decades, during which he held esteemed positions at the University of Chicago and Harvard University, retiring from Harvard in 2005. His scholarship significantly shaped the understanding of global conflicts and cultural exchanges between nations.

Born in Tokyo, Japan, on October 20, 1934, Iriye moved to the United States to pursue his higher education. He earned his Bachelor of Arts from Haverford College and his Ph.D. in history from Harvard University. His early academic journey and his bicultural perspective deeply influenced his approach to history, allowing him to bridge different cultural viewpoints in his analyses of international affairs.

Throughout his career, Iriye was recognized for his pioneering multinational approaches to "international history," which moved beyond traditional state-centric narratives to emphasize transnational interactions and the roles of non-state actors. This innovative perspective offered a more nuanced understanding of global dynamics and the interconnectedness of nations. His work consistently explored the complex relationships between Japan, the United States, and other global powers.

Iriye's contributions to the field were acknowledged with numerous accolades. He served as president of the American Historical Association in 1988, a significant achievement as the only Japanese citizen to hold that position. He also led the Society for Historians of American Foreign Relations. Among his many honors were the Order of the Sacred Treasure, Gold and Silver Star, one of Japan's highest civilian awards, and Japan's Yoshida Shigeru Prize for best book in public history. His election to the American Academy of Arts and Sciences in 1982 further underscored his impact on historical scholarship.
