Japan's population is aging and shrinking. If other demographic factors, such as retirement age or fertility rate remain unchanged, Japan will need large-scale labor migration in order to keep its workforce at a level that ensures the functionality of the state. The nation's political elites, however, are hesitant about opening Japan's doors to such migrants.
There is a vast amount of data available on Japan's demographic change, of which the most relevant is the decline of Japan's workforce. Data provided by Japan's National Institute of Population and Social Security Research (IPSS) shows the projected development of the Japanese population divided into age brackets. It forecasts a decline of those 14 years old and under; there is an even sharper decline predicted for those aged 15 to 64. Only those 65 years and older will increase in number. A nation's workforce is usually defined by the 15 to 64 age bracket; those who are 14 and younger, as well as those 65 and older, count as the non-working population. IPSS (2006: 12) predicts for Japan that the working and nonworking populations will almost equal each other at some 40 to 50 million each by 2050. This development would lead to the breakdown of the nation's social services, its economic power, and global competitiveness in general.
