What to Do When You Run Out of Medication in Japan

A prescription issued outside Japan cannot be filled at a pharmacy here - pharmacists cannot prescribe, and dispensing pharmacies (chozai yakkyoku, 調剤薬局) only fill a Japanese shohosen (処方箋). If you're running out of medication in Japan, the fastest path is to see a doctor here in person, bring your medication list in generic (INN) names, and, if you have one, a doctor's letter with your diagnosis and dosage. Japan runs a free-access system with no GP gatekeeper, so you can go straight to a relevant clinic and are often seen the same day or within a few days. Once the doctor writes a new shohosen, take it to a dispensing pharmacy - look for a sign reading 調剤 or 薬局 with a green cross, not a general drugstore (ドラッグストア), many of which have no dispensing counter. The pharmacy finder lets you filter for verified English support near you before you go. Only visiting? See bringing medication into Japan as a tourist.

Japan separates prescribing from dispensing, a system called 医薬分業 (iyaku bungyo). Doctors write a paper prescription; only a licensed dispensing pharmacy fills it, and clinics generally don't dispense on-site. Pharmacists work strictly from the shohosen - they can't prescribe, substitute a foreign script, or interpret a bottle label from another country. A standard shohosen is also only valid for four days including the issue day, weekends and holidays counted, so even a Japanese prescription has to be filled promptly or re-issued at another visit.

Brand names don't travel well. A drug that's easy to find at home may not be sold under that name here, or may not be marketed at all - the antidepressant lineup is narrower than in many Western countries, and stimulant ADHD medication is handled very differently, since Adderall and Dexedrine are banned outright rather than just restricted. Writing your list in generic, INN names, plus a doctor's letter with diagnosis and dosage, lets a Japanese doctor match you to an available equivalent fast instead of guessing from a brand name.

The best fix for running out of medication in Japan is not running out in the first place. If you're relocating, get an appointment before your supply runs low, and once you're an established patient with a stable chronic condition, ask about a refill prescription (リフィル処方箋), introduced April 2022 - usable up to three times without a full new consultation, though excluded for narcotics, psychotropics, and newly approved drugs. Keep your お薬手帳 (medication notebook) updated at every visit; it's free, and it's what lets a pharmacist catch interactions when you switch formulations.
