The Kanto Finance Bureau conducted a detailed analysis of the economic structural characteristics and recent economic conditions of its jurisdiction covering 1 metropolitan area and 9 prefectures (Tokyo, Kanagawa, Saitama, Chiba, Ibaraki, Tochigi, Gunma, Yamanashi, Nagano, and Niigata) as a report to the National Finance Bureau Directors' Meeting. This report comprehensively organizes the structural characteristics and current trends of the Kanto economic zone, which accounts for approximately 45% of Japan's economy.
The greatest characteristic of the Kanto region's economic structure is the extremely high proportion of the service industry. Services account for approximately 75% of regional gross domestic product, significantly exceeding the national average of about 65%. This reflects the concentration of financial institutions, corporate headquarters, government agencies, and research institutions in the Tokyo metropolitan area. The manufacturing sector accounts for about 15%, lower than the national average, but maintains high productivity with concentration in high-tech industries such as precision machinery, chemicals, and information technology equipment.
