In Brief

The ageing of Japan’s population is globally unprecedented both in its level and its speed.

The proportion of people aged 65 years old and over is now more than one-quarter of the total population of Japan — proportionally, the largest in the world.

This will grow to one-third of the total population in 2035. It took only 24 years — from 1970 to 1994 — for the proportion of Japanese people aged over 65 to increase from 7 per cent to 14 per cent. In European countries it took at least 50–100 years. Japan’s population has aged twice as fast as Germany’s and more than four times faster than France’s.

Even this understates the scale of the challenge. Not only are there proportionally more people over the age of 65, but the population over 65 is getting older. The proportion of people aged 75 years and over is increasing particularly rapidly, and is expected to reach 20 per cent of Japan’s population in 2035.

This ageing population has an enormous impact on Japan’s economy and society. Its most significant impact is on social security. As a result of this ageing population, total spending on social security was almost 110 trillion yen (approximately US$924 billion) in the 2012 fiscal year — 22.8 per cent of GDP.

Japan will have to make do with a smaller workforce. Productivity will have to increase if Japanese people are to enjoy the same living standards.

Japan should take every possible measure to cope with an ageing population. One step is of course to reverse the decreasing fertility rate. But even if the fertility rate recovered drastically, it would not make much difference to the dependency ratio, because newborns would not enter the workforce for some decades. Japan must therefore promote the employment of older people.

If older people with the will and ability continue working beyond the current retirement age, it will reduce the average per capita burden of the ageing society. The increase in the number of active workers and consumers in their old age would be a driving force of economic growth on the supply side as well as the demand side of the economy.

But Japan faces several obstacles that prevent it from promoting higher labour force participation among older people.

One obstacle is the public pension system. Any pension system will naturally make retirement more financially attractive to older workers. Japan’s current system includes strong incentives for pension-age Japanese workers to retire or to reduce their working hours, including an earnings test that lowers the pension rate the more you work. Japan should consider reforming pension eligibility to improve work incentives.

Mandatory retirement practices are still dominant in Japan. While having mandatory retirement from one’s primary job need not entail full retirement, in practice it often does. In Japan mandatory retirement reduces the probability of men aged 60–69 participating in the labour force, all other things being equal. Mandatory retirement also tends to push workers who stay in the workforce into jobs where their acquired skills and knowledge are underutilised, leading to a loss in productivity.

But if Japan revises mandatory retirement practices by lifting the legal minimum age of retirement or by introducing anti-age discrimination legislation, it will also need to change the seniority-based wage and promotion system. If a firm lifted the mandatory retirement age while leaving seniority-based wages unchanged, it would have to raise its wage bill considerably. Tackling this will require cooperation between unions and employer groups.

Encouraging older Japanese people to stay in the workforce will only mitigate part of the problem. The social security system also needs urgent reform.

Benefits for young people should be more generous, particularly with respect to childcare. In the late-1970s, when the fertility rate started declining, the Japanese government should have been concerned about population decline. But it took until the 1990s for the government to introduce the so-called ‘Angel Plan’ — a package of policies, which on the whole was not very daring, to promote comprehensive childcare support.

Unlike pensions, medical care, and long-term care — which are guaranteed revenue under Japan’s social insurance system — childcare has historically not had any permanent revenue source. So in 2013 the National Council on Social Security System Reform, which I chaired, recommended that the government should reserve revenue from the consumption tax for childcare.

Costs in both the pension and in the medical and long-term care systems must also be contained. Changing the pension eligibility age will help with the former, but medical and long-term care spending will be somewhat more difficult to restrain. They will increase at more than the rate of increase of the older population. This is not only because people over 75 years old are more likely to need medical and long-term care, but also because of the increase in the quality and the cost of medicine and care. Addressing this problem will require cooperation with service providers.

Japan’s high debt-to-GDP ratio means that social security system reform is vital. These reforms will no doubt face political opposition from both beneficiaries and service providers. But without them Japan will not be able to sustain the social security system that has enabled it to attain the highest longevity in the world for future generations.

4 responses to “Japan’s race against the ageing clock”

  1. What about the automation of jobs to make up for the lack of not having enough young people to fill them? But then again what will happen to the young people when they can’t get the jobs due to automation?

    Robert Reich, former American Secretary of Labor, gave an article on the website called Alternet, where he talked about how increasing automation is replacing American workers and the negative consequences it will create on the American economy where without jobs, people can’t buy services and goods of the future.

  2. This article has raised and answered many questions regarding demographic dividend v/s population control.
    The first point is clear: no country can afford to increase population without affecting living standard. Second, a person should not be allowed to retire till he is not able to work. He should be given some work with smaller salary thus keeping him in labour force. Retirement benefits should be smaller when he leave job completely thus encouraging him to be productive as far as possible.
    Population stabilization is the best way to sustain a society with good living standard.

  3. “Japan should take every possible measure to cope with an ageing population. One step is of course to reverse the decreasing fertility rate.”

    The Japanese fertility rate has been on a generally upward trend since 2005 albeit it with second decimal place declines in the last two years.

    Every standard statistical source shows this. It has been widely reported in both English and Japanese. For example, the fertility rate for 2015, the year of this article, was 1.46 up from 1.26 in 2005. (World Bank data)

    • Articles on EAF are fact-checked and peer-reviewed. Mr Kinmouth is correct in claiming that the Japanese fertility rate rose after 2005 but it has steadied and fallen to 1.4 (World Bank) in 2016, a rate which is lower that all major European countries except Greece, Spain, Portugal and Poland. The articles did not contest these qualified facts but simply argued that low fertility is a particular issue for advanced East Asian economies, which have average fertility rates lower than the European Union (1.6).
