Abstract
South Kanto industrial Zone, which developes around Tokyo, is divided into “East suburban industrial ligion” and “Kei-hin (Tokyo-Yokohama) industrial region”. Both are comblex industrial regions, but the former is old in origin and narrow in area, so the authors have treated the southern half of the region (Bokuto region) as an example of a complex industrial region. In the East suburban industrial region the factories of small or middle scale are crowded very densely, and the mobern factories of great scale are sittuaged on its marginal area. This is also the characteristics recognized in almost all industrial zones of Japan. Bokuto industrial region is divided into what is shown in Fig. 8, and its character is of the combination read in Fig. 7 : that is, the complex industrial area combined by the self-nurbisheousness of metallic ware industries as its center. By this analysis of complex industrial region it is distinctly recongnized that- (1) the location factors of factories, which is small or middle scale and densely crowed, are the industrial region itself (than is self-nurbishous) or the combination of industries in its region, on the contrary the factories of great scale stand by consideration of economic conditions : (2) the location factors of factories, of industries, and industrial regions are different.
