Tatsuhiro Oshiro (1925–2020) was a Japanese novelist and one of the leading figures of postwar Okinawan literature. Born in Nakagusuku, Okinawa, he worked for the Government of the Ryukyu Islands and later the Okinawa Prefectural Government while pursuing a literary career centered on Okinawa's history, culture, and identity. In 1967, he became the first writer from Okinawa to win the Akutagawa Prize with "Cocktail Party," establishing himself as a pioneering voice in modern Okinawan literature. His best-known work, "Cocktail Party," portrays life under U.S. administration in Okinawa and explores the tensions between occupation, justice, and human dignity.
