Exploring Medical Students’ Motivations to Apply for the Regional Quota Admission System: A Qualitative Study in Okinawa, Japan

Background The Faculty of Medicine at the University of the Ryukyus introduced a regional quota system to address the uneven distribution of physicians and specialties in remote islands and underserved areas of Okinawa Prefecture. Approximately 17 students are admitted annually under this system, which mandates graduates to work in designated regions or hospitals for a fixed period. Career choices are also constrained by limits on the number of students allowed into specific specialties. The motivations behind applying to the regional quota system remain varied and have not been sufficiently explored. This study aimed to clarify the reasons and motivations underlying students' decisions to pursue the regional quota. Methods Semi-structured interviews were conducted with 12 regional quota students enrolled in their first to fourth years of study. Participants were selected through purposive sampling. Each interview lasted approximately 45-60 minutes and was conducted face-to-face using a structured interview guide. The discussions were recorded, transcribed verbatim, and coded. Thematic analysis was performed following established six-step procedures (familiarization, coding, generating themes, reviewing, defining, and interpretation). Among the 12 participants, three were male and nine were female. The Clinical Ethics Committee of Unnan City Hospital approved the study. Results Thematic analysis revealed that both practical and value-based factors influenced students' decisions. Practical considerations included concerns about academic performance, anxiety over prolonged pre-admission periods, and financial benefits. Value-driven motivations included a strong desire to become a physician, commitment to serving their communities, and personal ties to remote islands. Many students also reported being influenced by family encouragement, financial support, and the pursuit of stability in life. Conclusion This study highlights the diverse motivations behind choosing the regional quota system. The findings suggest that clearer pre-enrollment information, structured mentorship, and flexible career support are needed to align students' expectations with program obligations. These practical measures may strengthen students' professional identity, increase satisfaction, and improve long-term retention in underserved areas.
