What sort of social character has Japanese city? Recent Urban Sociology doesn't try to ask such a total question. Rather, resent study has been made some progress by analyzing micro urban phenomenon. Among these situations, district group has been center of urban study. Especially the research of “Chonaikai” has been most concentrated. Not only has been pointed out that Chonaikai has the strong power to live itself, but also it has been said that the inclusive and territorial form of Chonaikai organization originate from Japanese Culture.
On the other hand, adjacent sciences, like Economics, Politics, Law and History have made it clear that the centralized authority of Japan has decisive effect on the formation of the social characters of city.
I should like to find out social character of Japanese cities, connecting relatively centralized authorities with Chonaikai of Macro and Micros. I will try here to show the following thing clearly : that is one of the characters of cities of our countrys, at least compared with those of European countries, have been devided to the inside of the cities by national state, as nothing but administrative unit of national state.
