Annual variation of the ratio of various activities in Tokyo and South-Kanto area (Kanagawa-ken, Saitama-ken and Chiba-ken) to the whole of Japan is surveyed. Various activities per capita are also investigated. (1) The concentration ratio of most items is nearly 10% of the whole of Japan, i.e. almost equal to the population ratio of Tokyo to the whole country. This situation does not change year by year. (2) The concentration ratio of some items, such as annual whole-sale sales, value of shipments of publishing, printing and allied industries, etc. is nearly 50%. However, this concentration ratio is reducing year by year. (3) The concentration ratio of some items, such as the clearing of checks and bills, the volume of sales of public and corporate bonds, domestic letters accepted, outstanding amounts of loans from all banks, number of bycycles, etc. is increasing year by year. Especially the concentration of the clearing of checks and bills and the volume of sales of public and corporate bonds in Tokyo is extraordinarily large, say 70%.
