Recently developments in the existing urban & local industry area destroy the local community network and the spatial characteristics, and the local industries are getting weaker according to the change of industrial structure, so that there is a need to make the sustainable urban & local industry space. Aims to get suggestions for that, this study focuses on the leather industrial area, which has mixed use spaces from modern times in the existing urban area of Tokyo.
The target area, Northern Taito Ward, is an area where the leather industry is located from early modern times which has been dominated the wholesale and secondary processing industry on a Family scale (integration & specialization of small scale industry). So that individual buildings in which residence and workshop functions are combined have been popular style in this area.
The methodology of this study (“A study on the fact and inheritance of urban Residential-Industrial mixed-use area from the view of Regional-Industrial structure”) is to incorporate the perspective of industrial structure with the discussion on the living environments of mixed-use spaces. So that the final goal is to disclose about the spatial characteristics of the target area and the importance of having view point of not only living but also industry networks in the argument on the mixed-used buildings.
As the First step, this paper discusses about the transition of regional-industrial structure in the target area, northern Taito-Ward from high economic growth period to the present in 4 steps.
In the first method, the statistical survey revealed the position of the target area; the northern part of Taito Ward, seen from the leather industry structure. Located in Tokyo, one of Japanese 2 major leather production areas, it is a region where the production of processed products of pigskin (especially shoes industry) is thriving and features a division of labor system.
Secondly, to catch the movement of transactions inside the area, we quantified the business relationships in the lists in 1970 and dropped them on the maps. Within the area, establishments located separately depending on the type of industry as well, and it was found that there was a high-density business relationship at short distance inside the area at that time.
Thirdly, we extracted the leather industrial establishments from the town page and made the current list. And finally, by comparing the location and business relationship of the establishments in 1970 with the current location, we caught the transition of the regional-industrial structure. There was no major change in the total number of leather establishments, but the number of manufacturers declined and the number of affiliated material stores increased. Distribution of the area by the industrial position tends to be distributed, and it turned out that commercialization occurred in the whole area.
In order to disclose that how the spatial elements of this area accepted the change of transactions, and how the influence form the town by appearing in the landscapes, we will investigate the fact situation of urban space of this area and compare the result with the transition of regional-industrial construction.
