What hospitals are near Karuizawa?

The main options are Karuizawa Hospital (the town's community hospital), Asama Nanroku Komoro Medical Center in nearby Komoro, and the larger Saku General Hospital / Saku Medical Center in Saku, which handles advanced and emergency care for the region. For minor issues you usually start at a local clinic, not a hospital.

Should I go to a clinic or a hospital in Japan?

For everyday illnesses and first visits, go to a local clinic (診療所/クリニック). Large hospitals are mainly for serious cases, specialist care, and referrals — and many charge an extra 'selection fee' (選定療養費) if you arrive without a referral letter (紹介状) from a clinic. Start small and get referred up if needed.

What is a referral letter (紹介状) and do I need one?

A referral letter (紹介状) is a document your clinic doctor writes to send you to a hospital or specialist. Many large hospitals require one for a first visit, or charge a sizeable extra fee without it. For non-emergencies, see a clinic first and ask for a referral if you need hospital-level care.

Where do I get my prescription filled?

In Japan, clinics and hospitals usually issue a prescription that you take to a separate pharmacy (薬局), often right nearby. Bring your insurance card and the prescription; some pharmacies have foreign-language support or can use interpretation services.

What do I do for medical care after hours or in an emergency near Karuizawa?

For a life-threatening emergency, call 119 for an ambulance. For urgent-but-not-critical issues outside clinic hours, look for the holiday/night duty doctor (休日・夜間当番医) or call a phone medical-advice line. Serious emergencies in this area are typically handled by Saku Medical Center. Carry your insurance card at all times.

Clinic or hospital? How the system works

Japan's system is built around starting at a clinic:

Clinics (診療所 / クリニック) handle everyday care — general/internal medicine (内科), pediatrics (小児科), dentistry (歯科), and so on. This is your first stop for most issues.
Hospitals (病院) are for serious conditions, specialist care, surgery, and emergencies.

To keep large hospitals focused on serious cases, many require a referral letter (紹介状) from a clinic for a first visit — or charge a selection fee (選定療養費), often several thousand yen, if you come without one. So unless it's an emergency, see a clinic first and ask for a referral if you need hospital-level care.

Finding a local clinic

Karuizawa town has clinics for common needs — internal medicine, pediatrics, dentistry, and more. To find one (and check any foreign-language support), use the searchable databases in our English-speaking doctors guide, or ask at the town hall. For anything language-sensitive, consider Nagano's medical interpretation service or bringing an interpreter.

Pharmacies (薬局)

Japan usually separates prescribing from dispensing: your clinic or hospital gives you a prescription, which you fill at a nearby pharmacy (薬局) — often just outside the clinic. Bring your insurance card and the prescription. Keep a list of your regular medications (ideally in Japanese) to show the pharmacist.

After-hours and emergencies

Life-threatening emergency: call 119 for an ambulance (same number as fire). Give your location and say "kyūkyū" (救急).
Urgent but not critical, after hours: look for the holiday/night duty doctor (休日・夜間当番医) rota, or call a phone medical-advice line to decide where to go.
Serious emergencies in this area are typically handled by Saku Medical Center.
The Karuizawa Guide lists healthcare contacts and emergency numbers in one place.

Before you go: a quick checklist

Bring your health insurance card (or linked My Number Card) — every visit.
Bring any referral letter (紹介状) if you have one.
Note your symptoms, allergies, and medications, ideally translated into Japanese.
Arrange language support if needed (interpreter or phone interpretation).
