Research Question : Should Retirement Ages Be Increased in Ultra-Aging Societies?

As populations continue to age, many countries are reconsidering their retirement policies. In ultra-aging societies such as Japan, the number of older adults continues to increase while the working-age population declines. This demographic change has created labor shortages and placed greater pressure on pension systems and government finances. As a result, raising the retirement age has become an important topic of discussion.

One argument in favor of increasing the retirement age is that people today generally live longer and remain healthier than previous generations. Many older adults are still capable of working beyond the traditional retirement age and wish to remain active. According to the OECD, encouraging people to work longer can reduce pressure on public pension systems, increase tax revenue, and help address labor shortages. Older workers also contribute valuable knowledge and experience that can benefit younger employees and improve workplace productivity. In Japan, policies have already been introduced to encourage companies to provide employment opportunities for workers up to the age of 70.  

However, raising the retirement age is not the best solution for everyone. Many older adults work in physically demanding occupations, such as construction, manufacturing, or healthcare, where continuing to work into their late sixties or seventies may be difficult. Others may experience health problems or become family caregivers, making full-time employment unrealistic. If retirement ages are increased without considering these differences, some older adults may face financial or physical hardship.

For this reason, many experts argue that retirement policies should be more flexible rather than simply requiring everyone to work longer. The Japanese Ministry of Health, Labour and Welfare has promoted measures that encourage continued employment while allowing workers and employers to choose arrangements that fit individual needs. Flexible options such as part-time work, gradual retirement, or changing to less physically demanding jobs can help older adults remain in the workforce without reducing their quality of life.  

Overall, increasing the retirement age can help ultra-aging societies maintain economic growth and support sustainable pension systems. However, successful policies should recognize that older adults have different health conditions, occupations, and personal circumstances. A flexible approach that combines longer working opportunities with better working conditions is likely to benefit both older workers and society as a whole.
