Japan is experiencing an unprecedented demographic shift, with record-low birth rates and a growing elderly population. The '2025 problem' refers to the year when Japan's large baby boomer generation, born between 1947 and 1949, will all be in their mid to late 70s, significantly increasing healthcare and social welfare costs. This puts immense pressure on Japan's shrinking working population, raising concerns about the sustainability of its social, health, and welfare systems.
Japan's total fertility rate has been among the world's lowest for about 70 years, currently standing at around 1.2, far below the 2.1 required for a stable population. While other countries like South Korea have even lower rates recently, Japan's long-standing low birth rate means it's a precursor for the long-term societal impacts of an aging population. Despite this, Japan has maintained economic success and social stability, prompting the world to observe its experience.
Japanese people are living longer, healthier lives due to economic success, a generous healthcare system, and healthy lifestyles. However, this longevity, particularly among the baby boomer generation, creates challenges for welfare, pensions, and care. These baby boomers, who fueled Japan's economic miracle, are now entering extreme old age, and the lack of a large younger population to support them constitutes the core of the 2025 problem.
Japan's coming-of-age ceremonies highlight the shrinking cohort of new adults; in 2024, only 720,000 babies were born, a record low since 1899. A critical factor is the declining marriage rate, as nearly all Japanese babies are born to married parents. Stagnant wages over three decades have created a surplus of 'economically unattractive men,' who are perceived as poor marriage material, leading to fewer couples forming and, consequently, fewer children.
Japan's early policies focused on encouraging married couples to have larger families. More recently, efforts include initiatives like a four-day work week to encourage dating and a government-backed marriage app. However, these measures are limited. The most significant, yet culturally sensitive, solution is increased immigration. While outwardly hesitant, Japan has quietly begun accepting more immigrants, including unskilled workers. Projections suggest foreign nationals could comprise 10% of the population within 20 years, a significant psychological and practical shift for the country.
Communities like Kirigaoka are seeing Indian immigrants slowly integrate with Japanese neighbors. However, the broader acceptance of lower-skilled workers across the country remains a question, especially given Japan's traditionally low immigration levels compared to Western countries. Without higher levels of immigration or a recovery in birth rates, Japan faces a long and challenging future. Its infrastructure will be heavily strained, requiring more nursing homes, hospitals, and carers, leading to a massive increase in government spending on the elderly.
The aging population has led to a significant increase in government spending on pensions and elderly support, now equivalent to about 10% of GDP. Innovation is also affected, with a decline in patents granted corresponding to the shrinking working-age population. However, the aging demographic has also created new business opportunities. Companies like Unicharm have shifted their focus from baby products to adult diapers, and food and beverage companies are adapting products for the elderly, like thicker, gelatinous teas.
Beyond caring for the living elderly, Japan must also cope with a rising number of deaths, leading to new services like 'funerals by proxy' for those without family. Japan's experience with economic growth amidst demographic decline offers a critical lesson for other nations. China, for instance, faces similar demographic headwinds due to its past one-child policy. While many countries are on a similar trajectory of demographic crunch, Japan's ability to maintain social stability, good health, and a competitive economy despite its demographic challenges provides a blueprint for what success can look like in an aging world.
