Japan has crossed a demographic threshold that would have sounded remote a generation ago: for the first time in its history, the country has more than 100,000 people over the age of 100.
The official total is 107,677, and nearly 90% of those centenarians are women. The surge has now continued for 56 straight years, while Japan’s record-low fertility rates keep pushing in the opposite direction.
The consequences are not abstract. The source says the growing population of centenarians is straining the country’s resources and creating a host of fiscal problems. It also says Japan’s pension system is buckling under the pressure.
To put the number in perspective, 107,677 is enough 100-year-olds to nearly fill AT&T Stadium in Dallas. That is the scale of the demographic inversion now confronting the world’s third-largest economy.
Japan is also trying to supplement its withering workforce by recruiting care workers from abroad. After reaching 66,000 last year under a skilled-worker visa program, the government will now allow nearly three times that many under a new foreign-aid worker plan, despite its usually strict immigration policies.
The numbers come first. A society cannot keep adding retirees at the top while the base of workers narrows at the bottom without forcing hard choices on taxes, pensions, and public spending. That is the arithmetic of the welfare state, and it does not negotiate.
For markets and policymakers, Japan’s problem is bigger than age. It is a warning about incentives, labor supply, and the long-term cost of a system built on promises that outlast the workforce expected to fund them. Capital rewards clear rules, but demography sets the hardest rules of all.
