Japan is grappling with an unprecedented demographic challenge as its population continues to shrink at an alarming rate. In 2024, the country recorded its largest-ever annual population decline, with the non-foreign population falling by 898,000 to 120.3 million. This marks the 14th consecutive year of decline, driven by a critically low birth rate and an aging society.
The total population, including foreign residents, also dropped by 550,000 to 123.8 million, highlighting the severity of the crisis. With only Tokyo and Saitama prefectures reporting slight population increases, the rest of Japan’s 45 prefectures saw declines, underscoring a national issue that threatens economic stability and social structures.
The Numbers Tell the Story
The decline in Japan’s population has accelerated over the past five years, reflecting deeper structural challenges. Below is a table summarizing the population drop for Japanese nationals from 2020 to 2024:
| Year | Population (Japanese Nationals, in millions) | Annual Drop (in thousands) | Total Population (including foreigners, in millions) |
| 2020 | 123.1 | 532 | 125.7 |
| 2021 | 122.4 | 644 | 125.5 |
| 2022 | 122.4 | 800 | 125.4 |
| 2023 | 121.6 | 861 | 124.9 |
| 2024 | 120.3 | 898 | 123.8 |
The data reveals a steady escalation in the annual population drop, with 2024 marking the largest decline since records began in 1950. The total population peaked in 2008 and has since contracted due to a birth rate among the lowest globally—only 730,000 births were recorded in 2023 against 1.58 million deaths.

Economic and Social Impacts
The shrinking population poses significant challenges for Japan’s economy and society. A declining workforce strains businesses, reducing productivity and innovation. Fewer consumers weaken demand, impacting industries from retail to real estate. The aging population, with nearly 29.4% of Japanese nationals over 65 in 2023, places immense pressure on pension and healthcare systems. Rural areas are hit hardest, with depopulation leading to abandoned communities and strained local economies. These trends threaten Japan’s long-term sustainability unless decisive action is taken.
Government Efforts to Stem the Tide
Recognizing the urgency, the Japanese government has implemented several measures to address the crisis. One key focus is boosting the birth rate by alleviating financial burdens on young families. Policies include increased subsidies for childcare, expanded parental leave, and financial incentives for couples to have children. The government has pledged significant funding—approximately 3.5 trillion yen annually—to support these initiatives, aiming to create a society where young people feel economically secure enough to start families.
Beyond encouraging births, Japan is cautiously expanding immigration to bolster the workforce. Recent reforms have widened job categories eligible for foreign workers, with pathways to permanent residency in some cases. The foreign population reached a record 3.3 million in 2023, providing critical labor in sectors like manufacturing and healthcare. However, large-scale immigration remains controversial, with cultural resistance limiting its scope.
Efforts also target regional revitalization to curb rural depopulation. Investments in infrastructure and incentives for young people to relocate to less populated areas aim to balance growth. Additionally, the government is promoting flexible work policies and wage increases for younger workers to address financial pressures that delay marriage and childbirth.
Challenges and Future Outlook
Despite these efforts, reversing the decline remains daunting. Financial incentives alone may not overcome deep-rooted social trends, such as later marriages and a preference for smaller families. Immigration, while growing, faces societal pushback, limiting its potential to offset the birth rate shortfall. Rural revitalization struggles against urban pull, with Tokyo continuing to draw young people away from other regions.
The government’s comprehensive approach signals commitment, but success hinges on sustained investment and cultural shifts. Encouraging work-life balance, reducing economic insecurity, and fostering openness to diversity could reshape Japan’s demographic trajectory. Without bold progress, the population could dip below 100 million by 2060, a threshold that would reshape the nation’s future.
