In the practice of Just-in-Time by Toyota Co., it is self-evident for economists and geographersthat many automotive parts suppliers are concentrated near car assemblers around Toyota City,because it enables mutual exchange of information, high quality control, and frequent deliverywithout surplus stocks.However, because of Toyota Company's capital power and high market share and the social historicalbackground in Toyota City, the agglomeration of automotive parts suppliers around car assemblersis not generally accepted in Japan. Toyota purchases many automotive parts fromdistant suppliers.On the other hand, some economists and geographers have thought Just-in-Time can be practicedby suppliers in dispersed locations, because high technology necessitates incentive capitalinvestments in a few factories or assembly lines. The many kinds of standardized or modularizedparts for a lot of car assemblers are intensively produced in one factory or assembly line to pursueboth economies of scale and economies of scope. Each worker on the shop floor is engaged inTotal Quality Control, improvement of working conditions (kaizen) to control and operate successiveseveral machines on the assembly line. Owing to such intensive working conditions, suppliers'locations are directed to obedient rural laborers.Therefore, the practice of Just-in-Time has been considered as consisting of a complicated interactionof agglomeration and dispersion, and its spatial implication shows various development.
