Japan’s healthcare system is highly accessible, affordable by international standards, and well-distributed across cities and regions. Understanding how the system is structured — the difference between clinics and hospitals, how to register, and what to expect at appointments — makes navigating healthcare far less daunting.
Japan’s Two-Tier Healthcare Structure
Japan’s medical care is organized into two main tiers:
- Clinics (クリニック / 診療所): Small outpatient facilities run by one or a few doctors. These handle the vast majority of routine care — colds, minor injuries, chronic condition management, regular checkups. Clinics specialize (internal medicine 内科, ear/nose/throat 耳鼻科, dermatology 皮膚科, orthopedics 整形外科, etc.) or offer general practice. No appointment often needed; same-day walk-in is standard.
- Hospitals (病院): Larger facilities with inpatient wards, surgery capabilities, and specialist departments. Japan’s large hospitals are generally not intended for routine care — many hospitals ask for a referral letter (紹介状 shōkaijō) from a clinic before accepting outpatient appointments. Going directly to a large hospital without a referral is possible but incurs an additional surcharge (¥5,500–¥11,000+).
The intended patient flow: clinic first → referral to hospital if specialist or inpatient care is needed. For expats: start with a clinic for most needs.
Health Insurance Coverage
All residents enrolled in Japan’s health insurance (either National Health Insurance — 国民健康保険 — or employer social insurance — 社会保険) pay 30% of medical costs at point of care; insurance covers the remaining 70%. Children under 18 and those over 75 have different co-pay rates.
Present your health insurance card (保険証 hōkenshō) — or My Number card if enrolled in マイナ保険証 — at every clinic or hospital visit. Without it, you’ll pay 100% and apply for reimbursement later.
How to Visit a Clinic
- Find a nearby clinic: Search Google Maps for the specialty you need (e.g., “内科 clinic near me” or “皮膚科 dermatology”). Many clinics list their foreign patient policy online.
- Check if appointment is required: Some clinics operate on a walk-in basis; others use an online or phone reservation system. Many now use apps like LINE for appointment booking.
- Bring your insurance card and residence card
- Fill out an intake form (問診票 monshin-hyō): Clinics provide a form asking about symptoms, medical history, allergies, and current medications. Many clinics now have multilingual intake forms or use translation apps.
- Wait and see the doctor: Waiting times vary from 15 minutes to 2+ hours at busy clinics. Some clinics display estimated wait times on their websites or apps.
- Collect prescription if needed: Doctors give you a prescription (処方箋 shohōsen) to take to a pharmacy (薬局 yakkyoku) — separate from the clinic. You pay for medication separately at the pharmacy.
Costs
With insurance enrolled (30% co-pay):
- Basic clinic consultation: approximately ¥500–¥1,500 out of pocket
- With tests (blood test, X-ray, etc.): ¥2,000–¥5,000 out of pocket
- Prescription medications: ¥500–¥3,000 out of pocket at the pharmacy
Japan’s clinic costs are genuinely low by international standards — regular healthcare is accessible without financial anxiety for enrolled residents.
Emergency Care (救急)
For emergencies: call 119 for ambulance (救急車). Ambulances are free to call and dispatch; you pay at the hospital for treatment.
For urgent but non-emergency situations (after hours, weekends): look for after-hours clinics (夜間救急診療所) or urgent care facilities in your municipality. Tokyo and Osaka have 24-hour urgent care centers. Your ward office’s website lists local after-hours options.
The #7119 shortline (in Tokyo, Osaka, and some other prefectures) connects you to a medical consultation service — tell them your symptoms and they advise whether to call 119, visit urgent care, or wait until morning. English interpretation is available on #7119 in Tokyo via a three-way call.
Annual Health Checkups (健康診断)
Japan has a strong preventive health culture. Employers are legally required to offer annual health checkups (定期健康診断) to full-time employees. Self-employed and NHI-enrolled residents can receive a subsidized municipal checkup (特定健診) arranged through their insurance. These cover basic blood tests, blood pressure, weight, and screening examinations.
Healthcare procedures, costs, and insurance coverage rules are subject to change. Verify current conditions with your clinic, insurer, or municipal health office. This guide provides practical orientation, not medical advice.
