In Japan, “clinic” and “hospital” are not interchangeable terms — they refer to fundamentally different types of medical facilities with different roles, capabilities, and costs. Choosing the right one can save you time, money, and frustration. This guide explains the differences and helps you decide which is right for your situation.
The Official Definitions
Under Japanese medical law, the distinction is clear and legally defined:
- Clinic (診療所 / shinryōjo or クリニック): A medical facility with fewer than 20 inpatient beds, or no beds at all. Most clinics in Japan have zero beds — they are outpatient-only facilities. Japan has over 100,000 clinics.
- Hospital (病院 / byōin): A medical facility with 20 or more inpatient beds. Hospitals have multiple departments, advanced diagnostic equipment, operating rooms, and the ability to provide long-term inpatient care. Japan has approximately 8,000 hospitals.
This distinction matters because it determines how the facility operates, what services are available, how much you pay, and how the appointment system works.
When to Go to a Clinic
Clinics are your first point of contact for most medical needs. Visit a clinic when you have:
- Common illnesses: Cold, flu, fever, sore throat, stomach pain, diarrhea
- Chronic condition management: Hypertension, diabetes, high cholesterol, thyroid disorders
- Mental health concerns: Depression, anxiety, insomnia, stress, burnout, adjustment disorder
- Skin problems: Rashes, eczema, acne
- Allergies: Hay fever, food allergies, medication reactions
- Minor injuries: Sprains, cuts, bruises
- Preventive care: Health checkups, vaccinations
- Documentation: Medical certificates, referral letters, prescription refills
Advantages of Clinics
- Shorter wait times: Clinics generally see you faster than hospitals, especially with an appointment.
- Personal attention: Many clinics are run by a single doctor who gets to know you over time. This continuity of care is valuable for chronic conditions and mental health.
- Lower cost: No additional fees for visiting without a referral.
- Convenient locations: Clinics are everywhere — in train station buildings, shopping streets, office complexes, and residential neighborhoods.
- Easier booking: You can usually get an appointment within days, sometimes the same day.
When to Go to a Hospital
Hospitals are for situations that require advanced resources:
- Emergencies: Severe injuries, heart attacks, strokes, serious accidents
- Surgery: Operations that require an operating room and anesthesia
- Hospitalization: Conditions that require overnight or extended inpatient care
- Advanced diagnostics: MRI, CT scans, complex blood work panels, biopsies
- Specialist consultations: When your clinic doctor refers you to a specialist at a hospital
- Cancer treatment: Chemotherapy, radiation therapy, surgical oncology
- Childbirth: While some clinics handle deliveries, most births in Tokyo take place in hospitals
The Referral System and the Extra Fee
Japan actively encourages patients to visit clinics first and hospitals only when needed. To enforce this, hospitals with 200 or more beds charge a special fee called the “tokutei ryōyōhi” (特定療養費) to patients who come without a referral letter (紹介状 / shōkaijō) from a clinic. This fee is:
- For initial visits without referral: ¥5,000 to ¥7,000 (varies by hospital)
- For follow-up visits after the hospital recommends returning to a clinic: ¥2,500 to ¥3,000
This fee is not covered by insurance — you pay it entirely out of pocket, on top of your regular copayment. The system is designed to prevent hospital overcrowding and ensure that hospitals can focus on patients who truly need their specialized resources.

Size Categories of Hospitals
Not all hospitals are the same. Japan categorizes them by function:
| Type | Description | Referral Fee? |
|---|---|---|
| Small hospital (20–199 beds) | Provides basic inpatient and outpatient care. Often accepts walk-ins. | No |
| General hospital (200+ beds) | Multiple specialties, advanced equipment. Encourages referrals. | Yes |
| University hospital (特定機能病院) | Teaching and research hospitals with the most advanced capabilities. | Yes (higher fee) |
A Common Misconception
Many foreigners assume that a hospital is always “better” than a clinic because it is bigger. This is not the case in Japan. For routine medical care, a clinic doctor often provides more personalized, attentive care than a hospital outpatient department. Hospital outpatient visits tend to involve long waits (sometimes 2 to 4 hours), shorter consultation times, and less personal attention.
The best approach is to find a good clinic as your primary care provider and use hospital services only when referred or in an emergency.
For Mental Health: Clinics Are Usually Better
Mental health care in Japan is predominantly provided at clinics rather than hospitals. Psychosomatic medicine clinics (心療内科) and psychiatry clinics (精神科) offer the private, comfortable environment that mental health patients need. Hospital psychiatry departments tend to focus on severe psychiatric conditions requiring hospitalization. For conditions like depression, anxiety, insomnia, burnout, or ADHD, a clinic is almost always the better choice. For more, see our article on mental health support in Tokyo.
