Japan's demographic shift is accelerating
Japan's foreign population increased by more than 300,000 people in one year while the country's working-age population continued to decline, according to new figures released by Japan's Statistics Bureau on September 24.
The final population estimates for April 1, 2026 show that Japan had approximately 3.92 million foreign residents, an increase of 301,000 — or 8.32% — compared with a year earlier.
At the same time, the number of people aged between 15 and 64 fell by 222,000 to about 73.34 million.

Japan's Japanese population continues to fall
The Japanese-national population declined even more sharply, falling by around 860,000 people over the year to approximately 118.92 million.
Japan is also continuing to age. The population aged 75 and older increased by 479,000, while the number of children under 15 fell by 356,000.
The Statistics Bureau's preliminary September estimate puts Japan's total population at about 122.65 million, 540,000 fewer than a year earlier.
What this means for the job market
The figures do not show how many of the additional foreign residents are workers. But they highlight the demographic pressure facing Japanese employers as the domestic working-age population continues to contract.
For international job seekers, the numbers are another sign of how quickly Japan's population structure is changing. Industries facing labour shortages have increasingly relied on a broader workforce, while policymakers continue to debate how migration and productivity can offset demographic decline.
