The present study explores organizational culture and management practices at a Japanese university. The study employed a qualitative approach to gain insights into the organizational culture and leadership strategies employed in diversity management. Semi-structured interviews were held with adjunct international faculty members to reflect on their personal experiences under the current leadership and its implications on diversity management. Findings revealed that top-down management approaches were counter-effective in the university’s efforts to promote diversity. Thus, the author proposed that inclusive leadership practices should be implemented to create a new organizational culture and harness diversity.
