This article assesses the planning, management and repatriation of Japanese civilians in Shanghai between 1945 and 1948. It examines four interwoven dimensions of this history. The first is the removal of Japanese expatriates as the centerpiece of the Kuomintang and Allied Powers' project to end Japanese colonialism once and for all. The second is how the Japanese community continued to exert a degree of autonomy and agency under the extremely unfavorable postwar circumstances. The third is the nature of postwar attempts to match each person with a definitive ethnic-national category. The fourth is how postwar history was experienced at the individual level among Japanese of different social strata and experiences.
