Population.—The population was as follows on the 31st of December 1907:—
| Population. | Males. | Females. | Totals. | Population per sq. m. |

The following table shows the rate of increase in the four quadrennial periods between 1891 and 1907 in Japan proper:—
| Year. | Males. | Females. | Totals. | Average increase per cent. | Population per sq. m. |
| 1891 | 20,563,416 | 20,155,261 | 40,718,677 | 1.09 | 272 |
| 1895 | 21,345,750 | 20,904,870 | 42,270,620 | 1.09 | 286 |
| 1899 | 22,330,112 | 21,930,540 | 44,260,652 | 1.14 | 299 |
| 1903 | 23,601,640 | 23,131,236 | 46,732,876 | 1.54 | 316 |
| 1907 | 24,601,658 | 24,172,627 | 48,774,285 | 1.13 | 330 |
The population of Formosa (Taiwan) during the ten-year period 1898-1907 grew as follows:—
| Year. | Males. | Females. | Totals. | Average increase per cent. | Population per sq. m. |
| 1898 | 1,307,428 | 1,157,539 | 2,464,967 | — | 182 |
| 1902 | 1,513,280 | 1,312,067 | 2,825,347 | 2.70 | 209 |
| 1907 | 1,640,778 | 1,476,137 | 3,116,915 | 2.37 | 224 |
According to quasi-historical records, the population of the empire in the year A.D. 610 was 4,988,842, and in 736 it had grown to 8,631,770. It is impossible to say how much reliance may be placed on these figures, but from the 18th century, when the name of every subject had to be inscribed on the roll of a temple as a measure against his adoption of Christianity, a tolerably trustworthy census could always be taken. The returns thus obtained show that from the year 1723 until 1846 the population remained almost stationary, the figure in the former year being 26,065,422, and that in the latter year 26,907,625. There had, indeed, been five periods of declining population in that interval of 124 years, namely, the periods 1738-1744, 1759-1762, 1773-1774, 1791-1792, and 1844-1846. But after 1872, when the census showed a total of 33,110,825, the population grew steadily, its increment between 1872 and 1898 inclusive, a period of 27 years, being 10,649,990. Such a rate of increase invests the question of subsistence with great importance. In former times the area of land under cultivation increased in a marked degree. Returns prepared at the beginning of the 10th century showed 2½ million acres under crops, whereas the figure in 1834 was over 8 million acres. But the development of means of subsistence has been outstripped by the growth of population in recent years. Thus, during the period between 1899 and 1907 the population received an increment of 11.6% whereas the food-producing area increased by only 4.4%. This discrepancy caused anxiety at one time, but large fields suitable for colonization have been opened in Sakhalin, Korea, Manchuria and Formosa, so that the problem of subsistence has ceased to be troublesome. The birth-rate, taking the average of the decennial period ended 1907, is 3.05% of the population, and the death-rate is 2.05. Males exceed females in the ratio of 2% approximately. But this rule does not hold after the age of 65, where for every 100 females only 83 males are found. The Japanese are of low stature as compared with the inhabitants of Western Europe: about 16% of the adult males are below 5 ft. But there are evidences of steady improvement in this respect. Thus, during the period of ten years between 1893 and 1902, it was found that the percentage of recruits of 5 ft. 5 in. and upward grew from 10.09 to 12.67, the rate of increase having been remarkably steady; and the percentage of those under 5 ft. declined from 20.21 to 16.20.
Towns.—There are in Japan 23 towns having a population of over 50,000, and there are 76 having a population of over 20,000. The larger towns, their populations and the growth of the latter during the five-year period commencing with 1898 were as follow:—
