Occupational physicians (OPs) in Japan share the same undergraduate and postgraduate medical training as other clinicians, forming a common medical foundation. However, their career entry points vary: some enter occupational health practice immediately after residency, whereas others transition following years of clinical experience. As a result, OPs bring heterogeneous clinical backgrounds into occupational settings, where their work is primarily non-curative, advisory, and preventive. In these roles, physicians are required to make judgments and recommendations at the interface of clinical medicine, legal obligations, and organizational management, often without direct responsibility for diagnosis or treatment . This differentiation raises a fundamental question: what constitutes “clinical competence” when physicians operate outside conventional curative practice? International frameworks, such as the Canadian Medical Educational Directives for Specialists and the Accreditation Council for Graduate Medical Education competencies, conceptualize physician competence as an integration of multiple roles, including medical expertise, communication, collaboration, and professionalism . In contrast, occupational health education in Japan has traditionally emphasized regulatory compliance and biomedical knowledge, while the practical integration of broader professional competencies into everyday occupational practice remains insufficiently articulated . As OPs increasingly address psychosocial issues, return-to-work coordination, and complex stakeholder interactions, there is a growing recognition of the need to better understand how clinical reasoning supports advisory and preventive decision-making in workplace settings . Previous qualitative studies have examined discrete aspects of OP practice, including communication with employers , fitness-for-work assessments , and ethical conflicts arising in occupational contexts . However, relatively little attention has been paid to how these activities are underpinned by integrated clinical reasoning processes in everyday occupational practice, particularly in contexts where physicians are not primarily responsible for diagnosis or treatment. Much of the existing literature describes competence in terms of identifiable knowledge or skills, but offers limited insight into how such competence is enacted and adjusted in practice under conditions of uncertainty, multiple stakeholder expectations, and organizational constraints.
