Abstract: Suicide remains a critical public health challenge in Japan, with the interaction between physical illness and psychiatric comorbidity emerging as a major determinant of risk. Patients with serious medical conditions face markedly elevated rates of suicidal behavior, particularly when depression or alcohol use disorders are present. Conventional preventive strategies, including screening and provider education, have yielded only modest effects. In contrast, collaborative care models that integrate psychiatrists, primary care physicians, and pharmacists demonstrate superior efficacy, significantly reducing suicidal ideation and attempts. Case management further enhances treatment adherence and clinical outcomes. Internationally, pharmacists play a pivotal role in medication management and suicide risk monitoring; however, in Japan their involvement remains limited by insufficient psychiatric training, institutional constraints, and inadequate reimbursement systems. Addressing these barriers through enhanced education, supportive policy reforms, and structured collaborative care frameworks could expand their role in suicide prevention. A comprehensive, multidisciplinary approach that strengthens pharmacist engagement may contribute substantially to reducing suicide risk among physically ill patients in Japan.
