Abstract
The document on public health presented by Dr.Sensai Nagayo contained great fruits of his new experiences in the 19th century America. So such a new knowledge from the fields of microbiology and other medical sciences was applied in the public health policy of early Meiji Japan. Especially many scientists and public administorators were interested in the relation between public health and civil engineering because main cities of east coast adopted the same technology. In the early Meiji period, the number of Colera sufferers exploded and the disease grew beyond the confines of the cities of Yokohama and other open ports. Many members of Dainihonshiritueiseikai, Kanehiro Takaki, Kyuichiro Nagai, and Toan Matsuyama discuss the effectiveness of civil engineering for public health, so called Eisei Kouji. In this report, I focus on Yokohama waterworks and Kanda sewer. In case of Yokohama, the construction expenses defrayed out of National Treasury. Owing to freigners' strong request, it went well smoothly. Because the government gave waterworks priority, the planning of sewers was deadlocked.
