A toothache in a new country is stressful, but dental care in Japan is one of the easier parts of the health system to use. Clinics are everywhere, much of the routine work is covered by national health insurance, and you do not need a referral — you can simply make an appointment yourself. This guide is an orientation to how the system works, so you know what to expect. It is not medical advice: for anything about your own teeth, see a dentist.
Finding a dentist
Dental clinics are usually called 歯科 (shika) or 歯医者 (haisha). You will see them on most shopping streets and near stations. A few practical ways to find one:
- Search 歯科 plus your station or neighbourhood name on a map app, and look for one within easy walking distance — handy since treatment often takes several visits.
- Use the Ministry of Health, Labour and Welfare's official medical information service (Iryou Joho Net), which lets you search registered clinics including dental clinics (歯科診療所) by area and language.
- Ask a neighbour, colleague, or your building manager — word of mouth is how many residents pick a regular dentist.
- Many clinics let you book by phone or through a web form; first-time patients are usually fine to book a few days ahead.
Insurance and what it covers
Most routine dental treatment — checkups, fillings, treatment for cavities and gum disease, scaling/cleaning, root canal work and simple extractions — is covered by Japan's national health insurance. With insurance you typically pay a 30% copay at the counter and the insurer covers the rest, at nationally fixed prices. Always bring your health insurance card (保険証 / マイナ保険証) to every visit. Some things are not covered and are paid in full privately — for example purely cosmetic work such as whitening, and many implants, orthodontics, and white/ceramic materials chosen for looks. If cost matters to you, ask the clinic in advance whether a treatment is insured (保険) or private (自費).
Bring your insurance card every time. Without it the clinic may charge you the full (non-insured) amount on the day. Whether a specific treatment is covered, and what it costs, is decided by the rules and your situation — confirm with the clinic, and for prices check the official source rather than relying on figures online.
What a visit is like
One thing that surprises many newcomers: dental treatment in Japan is often spread across several short appointments rather than done all at once. A filling, root canal, or crown may mean returning weekly for a few visits. This is normal and tied to how insured treatment is structured — it does not mean anything is wrong. Booking your next appointment before you leave makes the series go smoothly. Routine checkups and professional cleanings (scaling) are also commonly used here, and many residents go for a periodic checkup even without a problem.
Finding an English-speaking dentist
Many dentists handle a basic visit in simple Japanese, but if you would feel more comfortable in your own language, you have options. Tokyo's free Foreign Patient Medical Information Service (run by the Tokyo Metropolitan Government, the service historically known as Himawari) can help you find clinics with language support and answer questions about how the system and costs work — by phone on 03-5285-8181, in English, Chinese, Korean, Thai and Spanish, daily 9:00–20:00. For visitors, the JNTO Japan Visitor Hotline runs 24/7 in several languages and has a medical-institution search.
- Bring your insurance card and any current medication list to every appointment.
- Book your follow-up before you leave — treatment is often split across visits.
- Ask up front whether a treatment is insured (保険) or private (自費) if budget matters.
- Save a translation app or a few key words (痛い = it hurts, 親知らず = wisdom tooth) for the first visit.
- Consider registering with one nearby clinic as your regular dentist for checkups and cleanings.
If you have a serious dental injury, heavy uncontrolled bleeding, or facial swelling with fever or trouble breathing, treat it as a medical emergency — call 119 for an ambulance, do not wait for a dental appointment.
Dental emergencies and out of hours
Most clinics keep weekday hours and close on Sundays and holidays, so sudden tooth pain at an awkward time is a common worry. In Tokyo, the Tokyo Dental Association lists holiday emergency dental clinics (休日歯科応急診療) by ward and area for Sundays, public holidays and the year-end/New Year period. You can also ask the Tokyo Fire Department's emergency medical information centre where to go — 03-3212-2323 for the 23 wards, 042-521-2323 for the Tama area. These point you to care; for what is actually wrong and what to do, see a dentist.
- Do I need a referral to see a dentist?
- No. You can contact a dental clinic and book directly, including as a first-time patient. There is no need for a referral from a doctor.
- Why does my treatment take several appointments?
- Splitting treatment across short visits is normal in Japan and is tied to how insured dental care is structured. It does not mean there is a problem — just book the next visit before you leave.
- Is a checkup or cleaning covered by insurance?
- Treatment-related cleaning (scaling) and care for gum disease are generally covered under insurance. Purely cosmetic work such as whitening is not. Confirm with the clinic whether your visit is insured or private.
- What if I do not speak Japanese?
- Tokyo's free Foreign Patient Medical Information Service (03-5285-8181) can help you find clinics with language support and explain how the system works, in several languages, daily 9:00–20:00.
