When, however, feudalism was at last destroyed and in its place were established new forms of political and social systems which were much more liberal and advanced, the population suddenly began to swell at a tremendous rate. The advent of Occidental enlightenment which went far to improve the economic conditions of the country, and hence the conditions of living among the people, greatly encouraged the rapid multiplication of the number of people. Within the last fifty years the population of Japan has nearly doubled, increasing from thirty millions to fifty-five millions. At the present time the population is increasing at the rate of 650,000 to 700,000 per annum within Japan proper alone. The census taken on October 1, 1920, shows the total population of the Mikado's Empire as totalling 77,005,510, of which that of Japan proper is 55,961,140. The significance of Japan's population cannot be appreciated unless it is considered in connection with her land. The total area of Japan proper we have seen to be 147,655 square miles and the population close to 56,000,000. That is to say, the number of inhabitants per square mile is 380. This is rather a high figure when compared with that of other countries. Germany with her dense population counted, in 1915, 319 per square mile; France had 191, America 31 (1910), India and China, famous for density, had populations enumerated respectively at 158 and 100. Great Britain has rather a dense population (370 per square mile), but she has vast colonies, the population of which is extremely thin. This comparison of the number of people per square mile does not tell the true story until the quality and resources of each square mile are also compared. It has already been made clear that only 16 per cent., or fifteen million acres, of the land of Japan proper is tillable. This gives only one quarter of an acre of agricultural land per capita of population. In Great Britain agricultural land occupies 77 per cent. of the total area; in Italy, 76 per cent.; in France, 70 per cent. and in Germany 65 per cent. Industry.
