The core elements of Japanese politics, administration, and economics are concentrated to a high degree in the Tokyo metropolitan area. The population of Tokyo and its surrounding three prefectures of Kanagawa, Saitama, and Chiba, in particular, reaches 35,600,000, which is 28% of Japan’s total population of 128,000,000 (2010) and it is still increasing.
