The aim of working condition and ergonomics is to control the task method and condition for the best productive activity with the highest efficiency and sustainability. The Principles of Scientific Management by Frederick Winslow Taylor and its criticism by Gito Teruoka, the 1st director of The Institute for Science of Labour, are introduced for a better understanding of work condition and ergonomics in this article. Occupational physician have a duty to control working method and condition to reduce the health hazards induced by job duty. Not only the technical knowledge of medicine, but also a fundamental knowledge of manufacturing is needed for the occupational physician. The development of tools for early detection of health hazards and workload evaluation, the introduction of work management systems with cooperation between occupational physicians and technical experts of manufacturing are needed for effective control of the workplace. The strengthening of the Industrial Safety and Health Law should help to drive these improvements.
