Quick Answer
In Japan, doctors prescribe but do not dispense medications. You take your prescription (処方箋) to a pharmacy (調剤薬局) where you pay 30% of the drug cost. Always ask for generic drugs (ジェネリック) to save 30-50%. A typical pharmacy visit costs ¥500-¥3,000 depending on the medication.
How the Separated Dispensing System Works
Generic Drugs (ジェネリック医薬品)
Japan's government actively promotes generic drug use to reduce healthcare costs. The generic substitution rate has reached approximately 80%. When filling a prescription, pharmacists are required to inform you about generic alternatives. Generics cost 30-50% less than brand-name drugs with the same active ingredients.
Common Medications: Approximate Costs With Insurance
| Medication | For | Your Cost (30%, 1 month) |
|---|---|---|
| Loxoprofen (ロキソニン) | Pain/inflammation | ¥200-¥500 |
| Amlodipine (アムロジピン) | Blood pressure | ¥300-¥800 |
| Metformin (メトホルミン) | Diabetes | ¥400-¥900 |
| SSRI (Sertraline etc.) | Depression/anxiety | ¥500-¥1,500 |
| Antihistamine (Fexofenadine) | Allergies | ¥300-¥700 |
| PPI (Omeprazole) | Acid reflux | ¥300-¥600 |
Costs include dispensing fee. Actual amounts vary by pharmacy and whether generic is used. + dispensing fee ~¥500-¥800.
The Medication Notebook (お薬手帳)
Your medication notebook (お薬手帳/okusuri techo) records all prescriptions. Bring it to every pharmacy and doctor visit. It prevents dangerous drug interactions and can reduce your dispensing fee slightly. Many pharmacies now offer app-based versions.
⚠️ Disclaimer
Drug availability and pricing change. Some medications available overseas may be restricted or unavailable in Japan. If you take regular medication, consult a doctor in Japan about equivalent options before your supply runs out.
