In Japan, the service economy has progressed, and the industrial structure has become more sophisticated. On the other hand, in this study, we investigated whether these changes also occurred in areas where individual industries were concentrated. In this study, based on the triangular diagram, the cities, wards, towns and villages of Japan were classified according to the state of the industrial structure. As a result, from the 1980s to the 2010s, about 90% of local governments promoted service economy, and about half of them realized the sophistication of industrial structure. From the social map, it was confirmed that there are regional disparities such that the areas where the sophistication of the industrial structure has been realized are limited to the central part of the metropolitan area.
