Abstract: This is a subjective state-of-the-art report on the lifeline earthquake engineering in Japan. Beginning from the difference between civil engineering and building engineering in Japan, the paper briefly describes the evolution in the said field since early 70's. Depicted are the importance of and the lessons from the 1978 Miyagi-ken-oki earthquake in the Japanese lifeline earthquake engineering. Conservatism is one of the most notable characteristics in the earthquake-resistant design in Japan. It is stressed that good maintenance of lifelines in the ordinary times is by itself the most effective preparedness effort, and that this notion is beginning to be understood especially by large lifeline utilities.
