Japan foreign residents reach 4 million as regional housing demand evolves
Japan's foreign resident population reached a record 4.28 million in June 2026, even as the country's overall population continues to decline.
According to Immigration Services Agency figures released on October 16, the number increased by 155,631, or 3.8%, during the first half of 2026.

For Japan's housing market, the more interesting development is where these residents are settling and how their accommodation needs differ.
Foreign Population Growth Extends Beyond Tokyo
Tokyo remained home to Japan's largest foreign resident population, reaching 824,486 in June, an increase of 23,048 since December 2025.
However, neighboring prefectures and other major employment centers also recorded substantial growth.
Saitama: 305,867 residents, up 14,930
Kanagawa: 331,515 residents, up 14,162
Osaka: 389,846 residents, up 14,527
Aichi: 369,849 residents, up 12,049
Saitama's foreign population grew approximately 5.1% in six months, compared with Tokyo's 2.9%.
This suggests that housing demand associated with foreign residents could increasingly extend beyond Tokyo's central neighborhoods, particularly into areas offering more affordable accommodation and commuting access.
Employment Patterns Shape Housing Demand
Foreign residents do not represent a single housing market.
Japan had 444,256 residents under the Specified Skilled Worker program in June, an increase of 53,960 since December.
Another 516,184 held Engineer/Specialist in Humanities/International Services status, up 40,394.
Housing requirements vary depending on employment, household composition and length of stay.
Manufacturing workers may rely on company accommodation or shared housing, while longer-term residents may seek private apartments, larger homes or eventually homeownership.
Regional employment centers and resort economies in Hokkaido, Nagano and Niigata could also experience localized housing demand as their foreign workforces expand.
Population Growth Does Not Guarantee Higher Rents
An increase in foreign residents does not necessarily translate into an equivalent increase in rental households.
Some workers live in dormitories, share accommodation or join existing households.
Supply is another important consideration.
Japan had approximately nine million vacant dwellings in 2023, but many are located far from employment centers or are unsuitable for immediate occupation.
Consequently, even regions experiencing overall population decline can face localized housing shortages.
For property investors, foreign resident growth is a useful demographic indicator, but employment trends, transport access, available rental stock and local vacancy rates remain essential.
Japan's overall population may be declining, but residential housing demand can still grow in communities attracting new residents.
