Pharmacies & OTC Medicine in Japan: A Foreigner's Guide

Quick answer (30 seconds): In Japan, you buy everyday medicine at a "drugstore" (doraggu sutoa) — big chains like Matsumoto Kiyoshi, Welcia, Tsuruha, and Sundrug — which stock over-the-counter (OTC) cold, allergy, and pain medicines. A "dispensing pharmacy" (chōzai yakkyoku), usually next to a clinic, is for filling a doctor's prescription (shohōsen) and may not sell OTC cold medicine. OTC drugs are sorted into risk classes; the strongest (Class 1) sit behind the counter and need a pharmacist. When in doubt, ask the pharmacist — and always read the label.

Disclaimer: General information, not medical advice. Read labels, check ingredients against any prescriptions or allergies, and ask the pharmacist. For serious or persistent symptoms, see a doctor (or call 119 in an emergency).

Two kinds of "pharmacy"

• Drugstore (ドラッグストア / doraggu sutoa): your everyday shop for OTC medicine, toiletries, and daily goods. The big chains — Matsumoto Kiyoshi ("MatsuKiyo"), Welcia, Tsuruha, Sundrug, Cosmos — are everywhere and often have a pharmacist on site.
• Dispensing pharmacy (調剤薬局 / chōzai yakkyoku): usually next to a clinic/hospital. You bring a prescription (shohōsen), they prepare your medicine. These are not where you'd grab OTC cold medicine.

OTC medicine classes (why some is behind the counter)

Japan sorts OTC drugs by risk:

• Class 1 (第1類): the strongest OTC — kept behind the counter; a pharmacist must sell it and explain it (e.g., certain painkillers, some stomach medicines).
• Class 2 (第2類): common medicines like most cold and fever remedies — on the shelf, with guidance available.
• Class 3 (第3類): low-risk items (e.g., some vitamins, mild remedies).

For Class 1, staff may ask if you've bought similar medicine recently or take any prescription drugs — that's Japan's OTC safety rule, not nosiness.
