Choosing Between a Clinic and a Hospital

Japan’s two-tier care structure

Japan’s healthcare system is built on a deliberate two-tier model: small local clinics as the point of first contact, and larger hospitals and university medical centers as referral destinations for complex or specialist care. Understanding this structure makes navigating the system significantly easier and less expensive.

A clinic (クリニック or 診療所, shinryōjo) in Japan is typically a single-specialist or general medicine practice with fewer than 20 inpatient beds. Many have no inpatient capacity at all. Clinics see patients without appointments in many cases, have shorter wait times than large hospitals, and bill at the standard fee schedule without surcharges. For the vast majority of routine medical needs — a cold, a skin issue, blood pressure monitoring, a new symptom that needs assessment — a clinic is the right starting point.

Hospitals and the referral surcharge

A hospital (病院, byōin) is legally defined as having 20 or more inpatient beds. Hospitals range from small community hospitals to massive university medical centers designated as advanced care institutions (特定機能病院, tokutei kinō byōin). The larger and more specialized the hospital, the more strictly the referral requirement is enforced.

If you arrive at a large hospital (typically those with 200 or more beds) or at a specially designated hospital (大病院, daibōin) without a referral letter, the front desk will ask you to pay a surcharge (特別料金, tokubetsu ryōkin) in addition to your standard copayment. This surcharge is set by each hospital but is subject to minimum thresholds set by MHLW. It is not covered by insurance — it is an out-of-pocket fee on top of your 30%. At university hospitals, the surcharge for arriving without a referral can exceed ¥11,000 for an initial outpatient visit.

When a clinic is the right choice

Clinics are appropriate for most non-emergency situations: general check-ups, routine ongoing management of chronic conditions like hypertension or diabetes, minor infections, skin concerns, digestive complaints, respiratory symptoms, mental health consultations (where psychiatry clinics exist), and dental care at dedicated dental clinics.

Internal medicine clinics (内科, naika) are the general practitioners of Japan. They cover a wide range of adult conditions and can order blood tests and basic imaging. Many naika clinics are well-equipped to manage common chronic conditions indefinitely. If a naika physician determines that specialist input is needed — a cardiologist, a gastroenterologist, a surgeon — they will write a referral letter and direct you to an appropriate specialist clinic or hospital outpatient department.

When to go directly to a hospital

For emergencies, go directly to a hospital emergency department (救急外来, kyūkyū gairai) or call 119 for an ambulance. Emergency patients are triaged without regard to referral status, and no surcharge is applied in genuine emergencies.

Planned hospitalizations, surgical procedures, and specialist care for diagnosed conditions with documented history are also appropriately handled at hospitals — typically via the referral pathway. If you have been diagnosed with a serious condition by a clinic physician and need ongoing specialist management, your clinic will coordinate the referral.

Language considerations

Both clinics and hospitals vary significantly in their capacity to communicate with non-Japanese-speaking patients. Some large hospitals, particularly in major cities, have international patient centers with English-speaking staff or access to interpreters. Most community clinics do not.
