Social capital in immigrants has drawn considerable attention from social scientists. Previous studies have paid attention to how immigrants' bonding social capital (defined as social networks with co-ethnic residents) and bridging social capital (defined as social networks with native residents) are associated with their economic achievement. However, little attention has been paid to immigrants' different social capital's effects on psychological well-being. Drawing data from Chinese immigrants in Japan, we examined how these Chinese immigrants assimilated into Japanese society and how their bonding and bridging social capital related to their psychological well-being. The results show that bonding social capital directly affected immigrants' psychological well-being, whereas bridging social capital indirectly improved their psychological well-being by improving economic status. This study contributes to previous literature on how immigrants' different social capital is related to their psychological well-being.
