Last month the Ministry of Internal Affairs and Communications published its annual population report ahead of Respect for the Aged Day, revealing that people aged 65 and older now constitute a historic 29.6 per cent of the nation. Even more striking, 9.43 million of Japan’s workers are 65 or older, representing roughly 13.8 per cent of the total employed population. These figures illustrate that a sizable portion of the senior cohort remains economically active, underscoring the importance of their role in the country’s productivity.
A record share of seniors and a shrinking total population
The demographic tide is turning on two fronts. First, the The latest census, released by the Ministry of Internal Affairs for 1 October 2025, counted 122.9 million people—including foreign residents—down 3.17 million (2.5 %) from five years earlier. This marks the third consecutive decline in the quinquennial series that began in 1920.
Japanese citizens alone numbered 119.1 million a 3.5 % drop from the previous count, while the foreign resident population rose sharply by 39.8 % to a record 3.84 million. The largest foreign groups are Chinese (24 %), Vietnamese (15.9 %) and Koreans—both South and North—at 10.4 %. Meanwhile, the fertility rate stagnates around 1.2 children per woman far beneath the replacement threshold of 2.1, and the youngest age bracket (0-14) now makes up less than 11 % of the populace.
Projections and the looming “national crisis”
Demographers at the National Institute of Population and Social Security Research forecast a stark contraction: the total population could dip to 91.6 million by 2065 and further to 87 million by 2070. At that point, almost four out of ten Japanese would be senior citizens, placing the nation at the forefront of global aging.
Prime Minister Sanae Takaichi has labeled this trajectory a “silent national crisis” and promised a comprehensive population strategy by the end of the year. In her parliamentary address, she stressed that past measures were too fragmented and called for an integrated approach that tackles wages, childcare, and work-life balance simultaneously.
Government’s multi-pronged blueprint
The emerging plan aims to lift real wages for younger workers, extend direct child-care subsidies and redesign labour norms to encourage genuine paternity leave and reduced overtime. By reshaping lifestyle expectations, Tokyo hopes to make parenthood more attractive and sustain the dwindling birth rate.
Recognising the looming labour shortage, the administration also pledged massive investment in robotics, artificial intelligence and broader industrial automation. These technologies are expected to compensate for the shrinking workforce in critical sectors, from manufacturing to elder care, and preserve Japan’s global competitiveness.
While the data unveil a sobering reality—an aging society that is still largely active—the policy response signals a decisive shift. Whether the combination of wage reforms, family incentives, and high-tech solutions can reverse the demographic slide remains to be seen, but the government’s resolve marks a pivotal moment in Japan’s social contract.
