The concept of interprofessional work (IPW) is becoming increasingly important recently and the role of nurses in IPW seems critical. In Japan, the problem of burnout and turnover of nurses has been recognized, and the solution seems embedded in the scheme of IPW, because it appears to improve their job satisfaction and recognition as health professionals. However, many obstacles lie ahead, such as "tribal conflict" between health professionals including between pharmacists and nurses. Although failure to understand the roles of other professionals or competencies may seem to hamper with the promotion of collaboration, we must realize that even a lack of understanding among nurses exists. The authors believe that the solution is to understand and respect not only other professionals but also colleagues of the same profession.
