Various studies of demographic change in Japan have linked declining fertility to other changing social factors such as increased education, delayed marriage age, more economic opportunities for women, and the expense of raising children in modern, urban societies. All of these have played a role in reducing fertility over the past few decades. In addition, beyond delayed marriage many Japanese have chosen not to marry and, as a result, not have children. According to the 2010 census, 30% of all households in Japan were single, representing the largest category of household composition in the country. A significant portion of these households were widows over the age of 65. At the same time, a not insignificant portion were women and men in both early adulthood and middle-age who have simply chosen to not get married. In a society like Japan where child-birth out of wedlock is stigmatized, the decision not to marry also normally means that one has chosen not to have children.
Indeed, there are many women in Japan today in their forties and fifties who have opted for a career over marriage and child-rearing. In Japan, social pressures make it difficult for women to manage a career while also raising a family. Furthermore, recent trends suggest that both men and women are increasingly uncertain about the value of marriage and having a family. A government survey of people between the ages of 18 and 34 in 2011 showed that over 61% of unmarried men among those surveyed lacked a girlfriend and 49.5% unmarried women had no boyfriend, the latter being a new record. Forty percent of respondents indicated that there was no need to marry and 45% of men showed no interest in "dating the opposite sex." These results, which represented significant increases over the same type of survey conducted in previous years, have raised concerns that the population problem Japan is facing will not change in the foreseeable future.
The consequences of changing attitudes about marriage and gender roles and associated low fertility are considerable. One problem that has arisen is that many single women are living on very low incomes and have joined the ranks of the poor. Recent research has shown that 1 in 3 single women of working age in Japan qualify as poor and that the number of poor women in Japan is likely to increase; by 2030 it is projected that 1 in 5 women in Japan will be single. Many of these women may well be living in some level of poverty.Enjoying this article? Click here to subscribe for full access. Just $5 a month.
Another problem Japan faces is that the general low fertility rate means there are not enough younger people paying into the national pension program, and this will cause increasing strain on government coffers as the proportion of elderly (currently about 23% of the population is over 65) continues to grow.
Finally, the decline of the population over the next few decades, and the shortage of young people in particular, will have a significant impact on the Japanese labor force. Questions related to how to maintain economic growth—an issue that has been at the forefront of thinking about the country for the past twenty years, due to a generally sluggish economy—with a decreasing population are both complex and on the minds of policymakers. One obvious solution to this would be for Japan to relax immigration policies and allow for more workers, particularly healthcare workers, to enter the country. As noted above, to date this has not been a particularly palatable solution, but this may well change as younger Japanese, with regular experience and interactions with foreigners, move into positions of power and guide policy.
An alternative to this social-centered solution of increased immigration has been raised in recent years. Rather than relaxing immigration laws, some have proposed increasing investment in robotics as a means of addressing the conflict of a shortfall of labor with the need for workers. This idea has been raised particularly in relation to elder care, where demand for workers has increased rapidly with the promulgation of the longer term care insurance program in 2001 and the continued growth of the elderly population. It may well be that a technological solution to Japan’s population problem will be seen as preferable to other possible solutions.
Obviously, only time will tell. But Japan is faced with an unprecedented population challenge that will have social, economic, and political consequences over the next century—consequences that will not only affect Japan, but also influence Japan’s trading partners as well as its political and military allies.
There is, perhaps, no single variable in the complex web of East Asian politics more uncertain in terms of how it may influence future relations throughout the region than the fate of Japan’s population, because the manner in which that population changes over the next several decades is both difficult to predict and likely to have a profound influence in shaping the regional role Japan is able to play as a political, cultural, and economic power.
