This article examines two tutelage campaigns launched by Japanese social reformers targeting Japanese emigrant women in Manchuria and California in the first two decades of the twentieth century. It reveals how these two middle-class-based social campaigns jointly paved the way for the Japanese state's ‘continental bride’ policy in the late 1930s, which mobilized and exported women from across the nation to Manchuria on an unprecedented scale. Synthesizing the stories of Japan's colonialism in Manchuria and Japanese labour migration to the American Pacific coast, this study traces the convergence and flows between the women's education campaigns in Japanese communities on both sides of the Pacific. It moves the debate of Japanese imperialism beyond Asia and situates it in a transnational space encompassing the local, the national, and the global.
