Japan's Population Drops Sharply as Record Foreign Workers Alter Labor Market

The final results of Japan's 15th National Census released this year show that the total national population, including foreign residents, stands at 122,972,528. This represents a decrease of more than 3.17 million people, or 2.5 percent, compared to the previous census in 2020. This marks the largest population decline in Japan since the end of World War II, signaling that the trend of negative population growth has shifted from a gradual pace to a rapid one. The population decline is not merely a reduction in numbers; it directly impacts multiple dimensions, including the labor market, social security, and local governance.

The root causes of the population shrinkage have been clear for a long time: persistently low birth rates, changing views on marriage and childrearing, and increased female labor force participation have kept the total fertility rate hovering around 1.3 for years, well below the 2.1 required to maintain a stable population replacement level. At the same time, advancements in healthcare and welfare have steadily extended average life expectancy, with the proportion of the population aged 65 and older approaching 30 percent, placing Japan among the most aged societies in the world. This structural problem of a declining birth rate and an aging population means that the annual natural population decrease far exceeds any possible compensation from births, creating a vicious cycle of negative population growth.

The rapid changes in demographic structure have dealt multiple shocks to the Japanese economy. The continuous contraction of the labor supply has left traditional industries such as manufacturing, construction, and services facing severe labor shortages. Meanwhile, social insurance expenditures have risen rapidly due to the increasing proportion of elderly citizens, placing an increasingly heavy burden on public finances. To prevent declining productivity and reduced tax revenues, the government must find ways to supplement from external sources, which is the direct driving force behind the record-high number of foreign workers.

Over the past decade, Japan has gradually eased restrictions on foreign labor, from "specified skilled worker" visas to systems for "highly skilled professionals," all aimed at attracting foreign nationals with skills and experience. The latest statistics show that the foreign workforce has surpassed historical highs, with the proportion of foreign employees continuing to rise, particularly in labor-deficient sectors such as nursing care, agriculture, and construction. This trend has not only alleviated the employment crisis in some industries but has also brought the shock of multiculturalism and the challenges of integration to Japanese society.

Faced with the dual pressures of rapid population decline and labor shortages, the government and the private sector have begun deploying diversified countermeasures. In addition to continuously adjusting immigration policy, greater policy investments have been made in childcare subsidies, daycare services, and work-life balance initiatives in hopes of improving the environment for raising children. At the same time, promoting re-employment for the elderly and automation through robotics is being pursued to boost labor participation rates. Public acceptance of foreign workers still varies: some regions enthusiastically welcome foreign labor due to population drain, while others worry about cultural conflicts and employment competition. How to protect the rights of domestic workers while rationally utilizing foreign talent has become a core issue for future policies.

Overall, a population reduction of over three million in just five years is no longer an abstract statistic for Japan, but a practical challenge concerning the nation's future development. Although the record high number of foreign workers provides a short-term buffer, long-term solutions still require structural reforms, social support, and international cooperation to find a sustainable way out of the predicament of a declining birth rate and an aging society. Only by establishing a balance among population, the economy, and society can Japan maintain its competitiveness and vitality amid global changes. (Source: Central News Agency)
