The Pharmacy Next Door — Prescriptions, Generics, and the Medicine Notebook
In Japan, the doctor diagnoses and the pharmacy dispenses — almost always in two different buildings. Understanding this split, and the small rituals attached to it (the paper prescription, the medicine notebook, the generic question), turns a confusing extra errand into one of the system's better safety features.
Two kinds of "pharmacy"
The word covers two different shops. A dispensing pharmacy (調剤薬局) — often directly next to a clinic, marked 処方せん受付 — fills doctors' prescriptions, billed through your health insurance. A drugstore (ドラッグストア) sells over-the-counter medicine, cosmetics, and groceries; some larger ones contain a dispensing counter too, but the core business is OTC. For what's available over the counter and what isn't, see our medicine cabinet guide.
The prescription is paper, and it expires
After a clinic visit you'll usually be handed a prescription (処方箋, shohōsen) — take it to any dispensing pharmacy you like; the one next to the clinic is convenient but not mandatory. Two rules surprise newcomers:
- It expires in 4 days (including the issue date, including weekends). Miss the window and you're back to the doctor for a reissue, at your own cost.
- There are no automatic refills. The default assumption is that a prescription = one dispensing, and continuing medication means returning to the doctor — though usually just briefly.
Japan is slowly loosening the no-refill rule: since 2022, doctors can issue a refill prescription (リフィル処方箋) usable up to three times for stable long-term medication (not for narcotics, psychotropics, or newly started drugs). Uptake is still low and many doctors don't offer it spontaneously — but for a stable condition it is entirely reasonable to ask: 「リフィル処方は可能ですか？」. Electronic prescriptions (電子処方箋) are also spreading, tied to the My Number card, but the paper slip remains the everyday norm in 2026.
At the counter you'll pay your usual 30% share plus small dispensing fees. The pharmacist may ask about your symptoms — this is not nosiness but a legally required final check (they verify dose, interactions, and duplications independently of the doctor).
Say yes to generics — or don't, but know the default
The pharmacist will often ask: 「ジェネリックでもいいですか？」 — is a generic OK? Unless the doctor has specifically blocked substitution (a signature box on the prescription), you can choose. Generics in Japan pass the same bioequivalence standards as elsewhere; saying yes is medically sound and cheaper, and national policy actively pushes them — the substitution rate now exceeds 80%. If you have had a genuine problem with a specific generic formulation, saying no is also fine and no one will argue.
One recent wrinkle worth knowing: since late 2024, choosing a brand-name drug when a generic exists, purely by preference, incurs an extra charge (a portion of the price difference is excluded from insurance). Choosing brand for documented medical reasons remains fully covered.
The medicine notebook is quietly excellent
The お薬手帳 (okusuri techō) — a small booklet, free at any pharmacy — collects a sticker record of every medication you're dispensed, anywhere in the country. Its value shows up at exactly the moments you can't reconstruct your own history: a new doctor, an emergency visit, a drug interaction question, a pharmacy in another city, a disaster evacuation (it earned its reputation after the 2011 earthquake). Presenting it even slightly reduces your pharmacy fee at repeat visits; app versions (電子お薬手帳) are official and widely accepted, and link with the My Number infrastructure.
If you take any regular medication, keep one — and bring it to every medical encounter, including dentists. It is the closest thing Japan has to a portable medication record, and it costs nothing.
Practical extras
- Payment and hours: pharmacies attached to clinics keep clinic hours; drugstore dispensing counters often run later and on weekends — useful for a night-time prescription.
- Asking questions: pharmacists are an underused resource here, and major chains in cities increasingly staff some English speakers. The printed drug information sheet (薬情) that comes with your medicines includes the drug name in romaji — search it for the international name.
- OTC substitution: for minor complaints, pharmacists at drugstores can legally recommend and sell quite effective medication — Japan's OTC classes include drugs that are prescription-only elsewhere. Describe symptoms; let them work.
- Supplements and drugs from home: bring the actual bottles or a photo of the labels when asked what you take. Interaction checking only works if the pharmacist can identify the ingredient, and brand names rarely cross borders — see our medicine cabinet guide for the import rules.
General information. Dispensing rules and fees follow the national schedule and change with revisions; your pharmacist is the right person to ask about any specific medication — that is precisely what the system pays them to do.
