Japan will soon reach the point when the population decreases. The cause is the decrease in the birthrate. So, why did the number of babies decrease? One of the purpose of this paper is to clarify the situation during this time. Another purpose is to demonstrate that this reduction in population society is filled with economical possibility. The Japanese economy continued growth with the increase in population. However, the Japanese economy lapsed into depression over a long period of time, and faced reduction in population. In population reduction society, market contracts and employment and income are lost. Such pessimistic expectation spread. It withered consumption. And it aggravated depression. Surely, the reduction in population will reduce consumption, other thing being equal. However, reduction of population also decreases productive population. So, supply capability declines. In this way, both demand and supply decrease. However, when it is estimated from vital statistics and others, the reduction width of supply is larger than that of demand. If this happens, population reduction society will turn into a society which is under inflation pressure. This increases in expected earnings, then invites investment. It is growth-oriented economy. I accept the economical possibility of "population reduction society" in this way.
