New policy reviews say Japan’s healthcare system must evolve beyond hospital-based care to better support its growing elderly population and long-term care needs.
Japan’s universal health coverage has helped its people live longer than almost anywhere else in the world.
However, researchers now warn that the country’s healthcare system must undergo major reforms to keep pace with rapid population aging and rising long-term care needs.
According to two policy reviews published in the The Lancet Regional Health – Western Pacific, Japan needs to redesign its healthcare system and global health strategy by 2040 by shifting from hospital-focused care to community-based support and strengthening regional health partnerships.(1✔ ✔Trusted Source

Why Does Japan Need to Redesign Its Healthcare System?
Japan’s healthcare system was originally designed to treat acute illnesses in hospitals. However, the country’s health needs have changed significantly as its population continues to age.
By 2040, more than one in three people in Japan is expected to be aged 65 years or older, increasing the demand for long-term care for chronic diseases, dementia, and frailty instead of short-term hospital treatment.
According to the review, Japan’s healthcare system has entered a phase of “institutional stagnation,” where longstanding problems remain unresolved because the core structure of the system has not adapted to changing health needs.
A multidisciplinary working group comprising 25 experts from Japan and other Western Pacific countries identified several key challenges:
- Outdated healthcare payment models.
- Fragmented medical and long-term care data.
- Limited policy reforms.
- Growing pressure from an aging population.

What Reforms Could Help Japan Meet Future Health Needs?
The researchers recommend replacing the current hospital-centered, volume-driven healthcare model with a community-based system that focuses on people’s daily functioning, well-being, and quality of life rather than the number of medical services provided.
The proposed reforms include:
- Better integration of medical, long-term care, and welfare data.
- Greater use of scientific evidence in health policymaking.
- Payment systems that reward health outcomes instead of service volume.
- Increased investment in home-based care.
- Expanded use of digital health technologies.
- Stronger community-based integrated care services.
- Greater emphasis on preventive healthcare.
According to the authors, these reforms would better support older adults living with multiple chronic conditions while improving the long-term sustainability of Japan’s universal health coverage.

Why Is Global Collaboration Part of Japan’s Healthcare Vision?
The companion review recommends that health should become a central part of Japan’s human security diplomacy rather than being viewed primarily as foreign aid.
Researchers suggest strengthening collaboration with countries across the Western Pacific in areas such as:
- Infectious disease preparedness.
- Antimicrobial resistance.
- Medicine quality and safety.
- Artificial intelligence in healthcare.
- Digital health technologies.
- Combating health misinformation.
Instead of one-way knowledge sharing, the authors advocate mutual learning, where Japan shares its expertise in universal health coverage, long-term care, and disaster preparedness while also adopting successful innovations from neighboring countries, including community healthcare models, digital health solutions, and efficient healthcare financing systems.
What Can Other Aging Countries Learn From Japan?
The researchers emphasize that the findings extend far beyond Japan. As populations continue to age worldwide, many countries will need healthcare systems capable of delivering continuous, community-based care while remaining financially sustainable.
They conclude that redesigning the social contract behind universal health coverage—rather than simply preserving existing healthcare structures—will be essential to build resilient health systems that can respond to aging populations, future pandemics, climate-related health threats, and other emerging public health challenges.
