간단 답변

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.

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

MedicationForYour 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.

⚠️ 면책 조항

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.
