In the cotton thread and spinning factories of Japan, there are 81 girls to 19 men. Out of 1,000 girls, 386 are over 20 years of age, 317 are from 17 to 20, 191 are from 15 to 16, 73 are from 12 to 14, while 7 girls out of a thousand are under 12 years of age. The vast majority of factory girls live in the factory dormitories, which are of enormous size. In the region of Osaka there are more than 30,000 girls working in 30 factories; in these same factories there are less than 7,000 men. Three of these factories employ over 3,000 girls each, while three more employ 2,000 and upward. These girls are herded together in enormous dormitories, disastrous both to health and morals. Statistics covering a number of years show that out of every 1,000 girls, 270 work less than six months at the same place; 200 less than one year, 179 less than two years; 121 less than three years; 141 less than five years, and only 89 pass the five-year period. The usual reason for this extraordinary fluctuation of workers is that the girls break down in health. Government statistics declare that out of every 100 girls to enter upon factory work 23 die within one year of their return to their homes, and of these 50 per cent. die of tuberculosis. But it is also asserted that 60 per cent. of the girls who leave home for factory work never return. Of the criminal girls arrested in Osaka for a certain period, 49 per cent. had been factory hands. As to the education of factory girls it is stated that, out of 1,000, the number that had completed the required number of years of schooling (six) was 450, while 385 were entirely without education. Out of 1,000 girls, 453 were orphans. Of 1,000 girls, 611 came from farmers' homes, 166 from those of fishermen, and 55 from merchant homes, the remaining 168 being scattering. Factory girls earn and can save more than almost any other class. The average earnings per month are stated to be $4.67. The girl pays $1.20 per month for food, which is less than the actual cost, the factory providing the balance, namely, $1.30. The average girl sends home fifty cents per month. Three out of ten girls spend the balance entirely on clothes, five out of ten on cakes and theaters, while two out of ten save it. Such are some of the statements made by Mr. Uno in his enlightening book.
