Studies on Historical Relation between Japanese Population and her Farm Land.

Nowadays the population problems should be seriously discussed in our country. Japan being situated solitarily in the Asia Continent, her population has increased with comparatively slight influences of race movements. The increase of population is directly related with that of farm land which produces foods. Having studied the relation of the two with the lapse of age, I attemped to show them graphically by curves which may be termed "Historical relation between Japanese population and her farm Land." By resorting to this graph the density of the Japanese population in each age can be easily estimated. Taking into consideration the geographical conditions, I want to begin investigations before long not only on the farm land history, but also on some problems in the progressive process of society, especially of the agricultural one in our country
