In the period from 1886 to 1890, there were eighteen cases of planning and enacting of such codes throughout the whole country. In this treatise, in addition to the circumstances and the examples refered to in the enactment, local planning machines are mainly investigated and the following five points are clarified. 1) In Japan, first for the eight main cities and then for other cities, local building codes were planned or enacted. 2) Some laws or standards of Japan and foreign countries were refered to in planning. 3) In 1884, Yamaguchi Prefecture already enacted the like of a local building code. 4) It is clear that in five prefectures such as Ohsaka Prefecture, the prefectural sanitary sections planned these codes. 5) From the above-stated two examples and from the one of Tokyo Prefecture (mentioned in my last treatise), it can be educed that there was a trend to the enactment in some local governments already in 1884 and that sanitary sections took care of the planning work.
