History matters: the long-term impact of historical immigrant size on current xenophobia in Japan

Many studies have addressed how current immigrant size affects the strength of xenophobia from the perspectives of intergroup contact and ethnic competition theories. Can native residents’ current xenophobia be explained by historical immigrant size? To explore this question, we use historical immigrant size and a survey dataset to investigate the long-term effects of historical immigrant size on current xenophobia in Japan. The results show that historical immigrant size increases current xenophobia in Japan, which may be due to previous negative contact experiences between immigrants and native residents, and the negative effects persist. The implications of these findings for our understanding of the relationship between immigrant size and xenophobia are discussed.
