The Japanese Population Problem [PDF ebook] 
The Coming Crisis

This volume analyzes what the pressure of population growth in Japan in the early twentieth century consisted of and attempts to indicate what form it would take in the future. It examines not only the relationship between the number of inhabitants and the economic resources of the country but also discusses the structure and movement of the Japanese population, the agricultural potential of Japan, the prospects of importing food in return for exporting manufactures and the possibilities of finding relief through acquiring land further afield. The relation of all this to international affairs is stressed throughout.
