At a time when universities are experiencing a steep decline in enrollment rates, staff retention, integration, and commitment play an important role in the institution's sustainability. Thus, the current study aims to explore the effects of limited-term contracts (LTCs) on foreign language teachers' (FLTs') willingness to integrate on work-related and sociocultural levels. This research adopts a qualitative approach using questionnaires and interviews that focus exclusively on FLTs' LTCs at a university in Tokyo. Key findings are that LTCs do have a direct impact on FLTs willingness to integrate within their institutions at a peer and institutional level as previously highlighted by Chen (2022), Sato and Cotter (2017), Fuisting (2017), and Sato et al. (2015). However, limited effects were found at a classroom level. Additionally, evidence suggests that there is a correlation between sociocultural integration outside of work and willingness to integrate at the work-related level.
