This study examines the centrality and connectivity of major cities in Japanese urban system through relationships of corporate offices. After analysis of data concerning listed companies of five industrial sectors (textile products, chemicals, iron and steel, electric appliances, and transportation equipment) in 1985 and 2009, the following findings were obtained. Japanese inter-city network indicated that Tokyo, Osaka, and Nagoya had a significantly high degree of centrality. The degree of centralities of major core cities such as Sapporo, Sendai, Hiroshima, and Fukuoka were also high, but the disparity in their centralities was seen. Allocation patterns of branch offices ware different by sector, but branch arrangement patterns of company were quite similar within a same sector. Therefore, the inter-city relationships differ by sector.
