Japan’s population has declined by over 3 million in five years, highlighting a profound demographic crisis. As per preliminary census results released by the Statistics Bureau of Japan, the population now stands at 123 million, down from 126.1 million in 2020. This represents the largest decrease since the government began tallying census data in 1920.
Accelerating Population Decline
The trend of decreasing population is accelerating. Japan’s population peaked in 2008 at 128 million, and projections indicate it could plummet to 87 million by 2070. The current figures mirror those from 1989. For every new birth, there are now two deaths, revealing a stark imbalance.
Widespread Impact Across Regions
The demographic crisis affects nearly every region of Japan, with 45 out of 47 prefectures reporting population decreases in 2025. Notably, northern regions like Akita and Aomori have witnessed declines of approximately 8 percent since 2020. These areas host some of the oldest populations, and many young residents have migrated to urban centers seeking better opportunities.
Consequences for Rural Areas
Japan’s countryside faces significant challenges as young people leave. Rural schools are now transforming into nursing homes and community centers. Vacant homes abound, while government institutions and healthcare facilities scale back operations, and train services face shutdowns.
The Role of Immigration
Expanding immigration could mitigate some population losses. However, Japan has historically adopted a cautious stance on foreigners settling in the country. Nationalist sentiments are currently on the rise, complicating these discussions.
Regional Population Trends
- Okinawa: A rare growth zone, with a slightly increasing population and the highest fertility rate in Japan at 1.5 children per woman.
- Tokyo: The metropolitan area remains resilient, with its population increasing slightly to 37 million, constituting about 30% of the nation’s population.
Future Outlook
Demographic challenges are expected to worsen in the coming decades. There may be insufficient workers to support critical public sectors such as education and healthcare. As Professor James Raymo from Princeton University noted, Japan’s current measures to enhance fertility have not made significant progress.
Japan is a forerunner of demographic decline, and its situation may serve as a cautionary example for other countries facing similar issues in the future. Other nations in Asia and beyond are likely to confront analogous challenges as time progresses.
