Prescription Rules
How prescriptions work in Japan and what to expect.
From Doctor to Pharmacy
Doctor issues a prescription (処方箋)
After your clinic or hospital visit, the doctor writes a 処方箋 (shohōsen). This slip lists your medicines, dosage, and instructions.
Take it to a pharmacy (薬局)
You can use any licensed pharmacy (薬局, yakkyoku) — not just the one attached to the clinic. Many patients use their local 薬局 so the pharmacist knows their full medication history.
Pay for your medicine
With NHI: you pay 30% of the medicine cost. Without insurance: you pay 100%. Most prescriptions cost ¥200–¥1,500 with insurance.
Prescription is valid for 4 days
Japanese prescriptions expire after 4 days from the date of issue. Fill it promptly — you cannot use it after the expiration, and you'll need to revisit the doctor.
Important: Prescriptions in Japan expire 4 days after issue. Be aware of weekends. An expired prescription requires a new doctor visit.
Useful to Know
Generic drugs (後発品)
Ask the pharmacy for generic versions (後発品, kōhatsuhin). They are cheaper and equally effective. The pharmacist can explain options.
Dispensing fee (調剤料)
Pharmacies charge a separate dispensing fee (¥300–¥800). This is normal and is also covered 30% by NHI.
Medication notebook (お薬手帳)
Your pharmacist will offer an お薬手帳 (drug history booklet). Keep all your prescriptions here — it prevents dangerous drug interactions and helps any doctor you visit.
Bringing medicine from abroad
Some foreign medications are controlled or banned in Japan. Check before traveling. You can bring a 1–2 month supply for personal use with a doctor's note.
OTC medicines (市販薬)
Common medicines (cold, pain, stomach) are available over-the-counter at pharmacies (薬局) and drug stores (ドラッグストア) without a prescription.
