Complete Guide for Employees, Expats, and Long-Term Residents (2026)
Moving to Japan for work can be exciting—but understanding Japan’s healthcare system can feel overwhelming for many foreigners.
One of the most common questions foreign workers ask is:
“Is my company insurance enough, or should I also get private insurance?”
This guide explains everything working foreigners in Japan need to know about health insurance, including:
- How company insurance works
- The difference between public and private insurance
- Best insurance options for long-term residents
- Common mistakes foreign workers make
- How to choose the right coverage for your lifestyle
Whether you are an engineer, English teacher, office worker, freelancer, or corporate expat, this article will help you make smarter healthcare decisions in Japan.
Do Foreign Workers Need Health Insurance in Japan?
Yes.
If you work in Japan and stay for more than 3 months, you are generally required to join a public health insurance system.
For most full-time employees, this means:
Employees’ Health Insurance (Shakai Hoken)
This is Japan’s employer-sponsored healthcare system.
Your employer usually handles enrollment automatically.
What Is Shakai Hoken?
Shakai Hoken is a combination of:
- Health insurance
- Pension contributions
- Employment insurance
- Long-term care insurance
It is considered one of the strongest public healthcare systems in the world.
What Does Shakai Hoken Cover?
Shakai Hoken usually covers:
- 70% of medical expenses
- Doctor visits
- Hospital treatment
- Surgery
- Prescription medication
- Some dental care
You generally pay the remaining 30%.
Why Many Foreign Workers Still Buy Private Insurance
This surprises many newcomers.
Although Japan’s public insurance system is excellent, it does not fully eliminate financial risk.
Many foreign workers purchase additional private insurance for:
- Long hospital stays
- Cancer treatment
- Surgery benefits
- Income protection
- Private hospital rooms
- English-language support
- International medical coverage

Is Company Insurance Enough?
For some young and healthy workers, possibly.
However, many foreigners realize the limitations after:
- Emergency hospitalization
- Serious illness
- Family medical situations
- Long-term treatment
Even with public insurance, certain expenses can still become stressful.
Why Long-Term Residents Need Better Coverage
If you plan to stay in Japan for years—not just months—your insurance needs change.
Long-term residents should think about:
- Financial stability
- Family protection
- Future medical risks
- Aging-related healthcare
- Income interruption during illness
This is especially important for:
- Married couples
- Workers with children
- Permanent residents
- Mid-career professionals
- Freelancers

2. Cancer Insurance
Cancer insurance is extremely popular in Japan.
Why?
Because cancer treatment often involves:

3. Income Protection Insurance
Best for:
- Freelancers
- Self-employed workers
