Using the statistical data in Mortality Statistics of Tuberculosis 1947, (Published by Department of Statistics and Investigation, Welfare Minister's Secretaria) the authors studied regional differences in mortality of tuberculosis according to economic regions which had been provided by The Japanese Ministry of Agriculture and Forestry. These data are mortality statistics on residential places. In 1947 most of patients with tuberculosis (especially ex-servicemen who are afflicted with tuberculosis) were accomodated in either sanatoria or hospitals which situated in residential places. Consequently, it was inevitable that the tuberculosis mortality was high in those cities, towns and villages where institutions for tuberculosis are located. The results obtained are outlined below?F 1. The mortality due to tuberculosis in 1947 (to a population of 100, 000) stood at 187.2 for the whole country excluding Hokkaido, 229.6 for cities and 165.9 for countries. 2. The tuberculosis mortality by economic regions in the whole country excluding Hokkaido (to a population of 100, 000) represented 212.3 for the suburbs of cities, 170.4 for farm villages in a plain, 167.3 for farm and mountain villages, and 150.0 for mountain villages. Thus, it was proved that the more remote, the less the tuberculosis mortality becomes. 3. As with the whole country (excluding Hokkaido), the tuberculosis mortality by economic regions, and cities and prefectures, proved high in the suburbs of cities, but low in mountain villages. 4. It was found that all cities, towns and villages whose tuberculosis mortality rate (to a population of 1, 000) is over 10, were situated in the seats of national tuberculosis sanatoria.
