Securing process safety involves both technical and non-technical measures. While the latter lie outside the field of expertise of most engineers, neglect of non-technical measures can invalidate technical efforts. In matters of engineering ethics, regulation and compliance, and safety culture issues, considerable differences are observed between international trends and the Japanese nuclear world before the 2011 Fukushima nuclear accident. In the past, Japan has changed itself by accepting Western culture, first in the Meiji era and secondly after World War II. Now, we are facing a third chance to change. An effective way to learn and understand non-technical safety measures should be a consistent one, not a piecemeal one according topic. This paper proposes a new method of research and education in the law related to science and technology, and an improvement of ethical education for students and practicing engineers accompanied by a change of ethical vision.
