The Three Girls Revitalizing Asia, known simply as the Three Girls, was a transnational girl group briefly active in the 1940s. This trio of Bai Guang, Yoshiko Yamaguchi and Saiko Okuyama were part of Japan's cultural propaganda efforts during the Second World War, aimed at promoting the Greater East Asia Co-Prosperity Sphere—a concept that sought to create a bloc of Asian nations ruled by Japan, ostensibly free from Western imperialism due to being controlled by the Japanese colonial empire.
