Labour segmentation and outmigration in Japan: Evidence using firm–worker matching data

Abstract

AbstractDeterminants of foreigner outmigration from host countries have attracted considerable attention. However, minimal research examines the influence of firms’ working environments. Although the third largest economy, Japan's inability to attract skilled foreign labour remains a concern. This study is the first to investigate the effect of Japanese firms’ labour segmentation practices on foreign workers’ outmigration intentions. Segmentation refers to firms’ concentration on foreigner‐specific skills, regarding foreign labour as complementary to local workers. This is widely practised because of immigration policy's avoidance of substituting Japanese labour or causing unemployment. The findings suggest that although foreigner‐specific skills are highly valued in Japan, segmentation could significantly increase foreign workers’ outmigration intention. The lifetime employment system in Japan, job satisfaction and original migration motivations also affect outmigration. The results indicate that Japanese policies encouraging firms to employ foreign workers as complementary may harm its attractiveness to skilled foreign labour.
