In 1942, all Japanese were evacuated from the West Coast and incarcerated in internment camps. To investigate the long‐run economic consequences of this historic episode, I exploit the fact that Hawaiian Japanese were not subject to mass internment. I find that the labor market withdrawal induced by the internment reduced the annual earnings of males by as much as 9%–13% 25 years afterward. This is consistent with the predictions of an economic model that equates the labor market withdrawal induced by the internment with a loss of civilian labor market experience or a loss of advantageous job matches.
