Japan has one of the world’s most comprehensive preventive healthcare systems, and regular health checkups (健康診断, kenko shindan) are a central part of it. As a foreign resident, you have access to the same checkup systems as Japanese nationals — and in many cases, you’re legally required to participate. This guide explains how health checkups work in Japan and what to expect.
Why Health Checkups Matter in Japan
Japan’s approach to healthcare is strongly preventive. Regular screening catches conditions early — before they become expensive or life-threatening. The system is built around the assumption that annual checkups are standard, not exceptional. Many conditions — metabolic syndrome, hypertension, certain cancers — are caught and managed effectively because of this culture.
As a foreigner living in Japan, participating in the checkup system is not only practically useful but often socially expected in a workplace context.
Types of Health Checkups in Japan
1. Employer Health Checkup (Jigyonushi Kenko Shindan)
All employers are legally required by the Industrial Safety and Health Act to provide annual health checkups to full-time employees. This applies to foreign workers equally.
What’s typically included:
- Height, weight, BMI, waist measurement
- Blood pressure
- Vision and hearing tests
- Chest X-ray
- Blood tests: complete blood count, liver function, kidney function, cholesterol, blood sugar
- Urine test
- ECG (electrocardiogram) for older workers
The checkup is arranged by your employer (usually at a contracted clinic or medical center) and is free for employees. You simply show up at the appointed time.
Results are typically returned within 1–2 weeks, often with a letter grading each category (A through D or equivalent). Items flagged for follow-up should be taken seriously — follow-up care is your own responsibility.
2. Municipal Health Checkup (Tokutei Kenko Shindan — “Toku-Ken”)
For residents enrolled in national health insurance (Kokumin Kenko Hoken) who are aged 40–74, your municipality provides a free annual health screening called Tokutei Kenko Shindan (specific health checkup).
A notification is sent to your registered address in spring. Contact your ward office or health insurance provider if you haven’t received one by May.
For residents under 40 on national health insurance, some municipalities offer optional basic checkups at low or no cost — check your ward office website.
3. Cancer Screenings (Gan Kenshin)
Municipal cancer screenings are available for foreign residents as well:
| Cancer | Eligible Age | Frequency |
|---|---|---|
| Stomach cancer | 40+ | Every 2 years |
| Lung cancer | 40+ | Annual |
| Colorectal cancer | 40+ | Annual |
| Cervical cancer | 20+ | Every 2 years |
| Breast cancer | 40+ | Every 2 years |
These are offered at low cost (¥500–¥2,000 per screening) through your ward office. Check your municipality’s health and welfare department for scheduling.
4. Comprehensive Medical Examinations (Ningen Dock)
Ningen Dock (人間ドック) is a comprehensive medical checkup that goes far beyond the standard employer checkup. It typically includes:
- All standard tests
- Endoscopy (stomach and/or colonoscopy)
- CT scan or MRI
- Cardiac stress test
- Detailed cancer markers
- Ophthalmology exam
- Dental assessment (some packages)
Cost: ¥30,000–¥100,000+ depending on package. Some health insurance plans offer subsidies. Worth considering at 40+ or if you have family history of serious illness.
Understanding Your Results
Japanese health checkup results often use letter grades or number codes. A common system:
- A: Normal
- B: Minor abnormality, monitor
- C: Requires attention, follow-up recommended
- D: Abnormality found, further examination required
- E: Under treatment
Items in categories C and D should prompt you to visit a clinic. Your checkup report usually indicates which department to consult.
Supplementing Public Healthcare with Private Insurance
Japan’s public health insurance covers most medical costs effectively, but there are gaps — particularly for serious illness requiring extended hospital stays, surgery with significant income loss during recovery, or specialized treatments. Many residents combine public insurance with private supplemental policies.

Language Considerations
Most checkup forms and result letters are in Japanese. At larger urban medical centers, English translation support may be available — call ahead to confirm. For employer checkups, your HR department can often provide translation assistance.
