Healthcare and Medical System in Japan: A Complete Guide for Foreign Residents

Japan has one of the world's best healthcare systems, and as a foreign resident, you are entitled to access it once you enroll in the national health insurance program. Understanding how the system works will help you get the care you need without confusion or unexpected costs.

National Health Insurance (Kokumin Kenko Hoken)

All residents of Japan — including foreigners — are required by law to enroll in a health insurance program. If your employer does not provide company health insurance (Shakai Hoken), you must enroll in the National Health Insurance (NHI) program through your local city or ward office.

How to enroll in NHI:

Visit your local city hall (shiyakusho) or ward office (kuyakusho)
Bring your residence card (zairyu card), passport, and My Number card
Complete the enrollment form — many offices have English support
Premiums are income-based; the office will calculate your monthly payment

NHI covers 70% of most medical costs, meaning you pay only 30% out of pocket. For low-income households, premium reduction programs are available.

Company Health Insurance (Shakai Hoken)

If you are a full-time employee, your company will likely enroll you in Shakai Hoken, which includes health insurance and pension. Your premium is split equally with your employer, making it more affordable than NHI.

Company insurance typically provides the same 70/30 coverage and may include additional benefits like dental support or health checkup coverage.

Finding a Doctor and Hospital

Japan's healthcare system is structured around clinics (クリニック) for minor issues and large hospitals (病院) for serious conditions. For everyday needs like colds, fevers, or minor injuries, visit a local clinic — they are faster and cheaper than hospitals.

Finding English-speaking doctors:

AMDA International Medical Information Center: 03-5285-8088 (Tokyo)
Japan Helpline: 0570-000-911
Himawari Healthcare Navigation: 03-5285-8181
Online directories like "Japan Doctor Search" and "Expat Med" list English-speaking clinics

Many university hospitals and international clinics in major cities offer multilingual services. Cities like Tokyo, Osaka, Nagoya, and Fukuoka have dedicated international medical centers.

What to Expect During a Hospital Visit

When visiting a clinic or hospital for the first time, you will need to present your health insurance card (hoken-sho). Keep this card with you at all times — it proves your enrollment and activates your 30% co-pay discount.

Typical hospital visit process:

Register at the reception desk (受付) — bring your insurance card and ID
Fill in a medical questionnaire — ask for an English version if needed
Wait to be called for your appointment
See the doctor — consultations are often brief (5-10 minutes) in public hospitals
Receive a prescription if needed — take it to the hospital pharmacy or a nearby pharmacy
Pay at the checkout counter — you pay only your co-pay portion

Mental Health Services

Mental health awareness in Japan has improved significantly. Services available include counseling centers, psychiatric clinics, and hospital psychiatry departments. Many urban areas now have English-speaking therapists and counselors.

Emergency Services

In a medical emergency, call 119 for an ambulance (救急車). Emergency services are free to call. When calling, state your location clearly. Major hospitals have emergency departments (救急) open 24 hours.

If the situation is not life-threatening, you can visit an "after-hours clinic" (夜間診療所) for evening or weekend care.

Prescription Medication

Most prescription medications are available at Japanese pharmacies. Bring your doctor's prescription (処方箋) to any pharmacy displaying the green cross symbol. If you rely on regular medication from your home country, consult a Japanese doctor early — some foreign medications are not approved in Japan and require substitutes.

Annual Health Checkups

Japan has a strong culture of preventive healthcare. Many employers offer free annual health checkups (健康診断) which include blood tests, chest X-rays, and more. If you are enrolled in NHI, your city office may offer subsidized checkup programs too.

Taking advantage of these checkups is strongly recommended — early detection is highly valued in Japanese medical culture.
