This paper studies the process and meaning of the enactment of exhaust emission control in Japan. In the 1960s, the health hazards caused by exhaust emission became a serious social problem. The existing controls implemented by the Transport Ministry had been based on insufficient research, and emissions were not regulated by numeric values. The Ministry therefore underwent another study and surveyed the effect of exhaust emission on air pollution. It also weighed the opinions of automobile companies in drafting new regulations. But the resulting regulations proved to be only transitional. Because the study of exhaust emission was not thorough enough, controls were made only on CO, in effect reflecting the technical capabilities of the automobile companies and having only a limited effect on decreasing air pollution. But it did have some significance as it served as the foundation for exhaust emission control thereafter and reduced CO of individual cars. The regulation led automobile companies to question air pollution in Japan and improve their products. This was a typical case in which national opinion on regulation influenced the Ministry into taking the initiative to control exhaust emission.
