How long is a prescription valid in Japan?

Standard prescriptions in Japan are valid for four days from the date of issue (the day of issue counts as day one). If you cannot fill it within this window, contact the prescribing clinic — they can reissue it. Long-term prescriptions for chronic conditions may be issued for longer periods.

Can I request generic medications in Japan?

Yes. Generic versions of most medications in Japan's formulary are available and are dispensed unless the prescriber has explicitly indicated brand-only. When filling a prescription, the pharmacist may ask whether you prefer the generic or brand-name version. Generics are bioequivalent and typically less expensive — your 30% copayment on a generic is lower in absolute terms.

What if a medication I take is not available in Japan?

Some medications prescribed abroad are not approved for sale in Japan, or are sold under different names. Bring your original packaging and any documentation from your previous prescriber. The Japanese pharmacist or clinic physician can look up equivalents. For controlled substances, additional import documentation is required — contact your country's embassy and Japan's MHLW for the relevant permit process.

Do pharmacies in Japan speak English?

Pharmacies in tourist areas and near international hospitals often have some English capability. Chain pharmacies (Welcia, Matsumoto Kiyoshi, Sundrug, etc.) may have staff with limited English. In most community pharmacies, communication is in Japanese. Consider using your okusuri techō as a communication tool — the medication stickers are in Japanese but a pharmacist can read your history from it directly.

Pharmacies and Prescriptions in Japan

How Japan’s prescription-pharmacy system works

In Japan, the dispensing of prescription medications is separated from the prescribing clinic. When a physician prescribes medication, they issue a paper prescription slip (処方箋, shohōsen) that you take to a freestanding pharmacy (薬局, yakkyoku). The pharmacy dispenses the medication and bills your insurance for its covered share; you pay the 30% copayment at the pharmacy counter.

This separation is deliberate policy — Japan moved toward a dispensing-prescribing split (医薬分業, iyaku bungyō) to reduce opportunities for physicians to profit from prescribing their own pharmacy stock and to have an independent pharmacist review prescriptions for errors and interactions. The practical effect is a two-stop process: clinic first, then pharmacy.

Finding a pharmacy

Look for 薬局 (yakkyoku) or 調剤薬局 (chōzai yakkyoku — dispensing pharmacy) signs. There are typically several pharmacies clustered near clinics and hospitals to capture prescription traffic. You are not required to use a pharmacy affiliated with or near your clinic; you can take your prescription slip to any licensed pharmacy. Many prescriptions for common medications are filled quickly — under 15 minutes for straightforward prescriptions.

Chain pharmacies (Welcia, Matsumoto Kiyoshi, Sundrug, Ainz & Tulpe, and others) are widely distributed and generally maintain consistent stock. Smaller independent pharmacies may have more limited stock but can often order medications by the next business day.

Filling a prescription

Hand your prescription slip to the pharmacist at the counter. They will verify the slip, ask if you have your okusuri techō (medication record book), and may ask a few questions about any allergies or other medications. The dispensing process typically involves:

Verification of the prescription and your insurance card
Preparation and packaging of the medication
A brief pharmacist consultation (薬剤師の説明, yakuzaishi no setsumei) — mandatory by regulation — explaining the medication’s purpose, dosage, timing, and important interactions or side effects
Payment of your copayment

The pharmacist will paste a sticker record of the dispensed medication in your okusuri techō (if you have one) before handing everything to you.

The okusuri techō — your medication record book

The okusuri techō (お薬手帳) is a small booklet issued by pharmacies to track all prescriptions you receive over time. Every pharmacy in Japan recognizes and can paste stickers into it. It is yours to keep and carry between different prescribers and pharmacies.

Present it at every medical appointment and every pharmacy visit. The pharmacist uses it to check for interactions between your current prescriptions before dispensing anything new. If you do not have one, ask your pharmacy on your first prescription visit — they will issue one for free.

Generic medications

Japan has an active generic medication market. When you present a prescription, the pharmacist may ask whether you would prefer the generic equivalent (ジェネリック医薬品, jenerikkku iyakuhin) of a brand-name medication. Unless the physician has explicitly prohibited substitution, generics are always an option. They are bioequivalent, regulated to the same standard by MHLW, and typically cost less — your 30% copayment is lower in absolute yen.

Bringing medications from abroad

If you are moving to Japan with ongoing prescriptions from another country, research early whether your medications are available in Japan under the same name or an equivalent. Japan prohibits bringing in more than a one-month supply of most prescription medications without prior import authorization. For controlled substances (opioids, benzodiazepines, stimulants), you must obtain a narcotics import certificate (麻薬輸入許可書) from MHLW before arriving. Contact your country’s embassy in Japan and the nearest MHLW regional bureau well in advance of travel.
