Migraine Medication in Japan: Triptans and OTC Options

Triptan-class migraine medication is available in Japan, but only by prescription - it isn't sold over the counter anywhere. For milder attacks, ibuprofen and acetaminophen are sold OTC at every drugstore in Tokyo, no prescription needed. If you're on a triptan at home, the practical path is getting established with a doctor here rather than stretching out what you brought.

Japan splits medicine into OTC classes and prescription-only drugs, and migraine treatment sits on both sides. Ibuprofen and acetaminophen are general-purpose OTC painkillers, sold at drugstores (ドラッグストア) without a doctor visit, and can be enough for a mild-to-moderate attack. Triptans work differently - they act on the specific mechanism behind a migraine, not just pain in general - and Japan classifies them as prescription drugs. No drugstore or OTC class covers them; you need a shohosen (処方箋) from a doctor, filled at a dispensing pharmacy.

Sumatriptan and other triptans fall under the same rule as any other prescription drug: Japan allows up to a 1-month supply in personal luggage without needing an import certificate. Carry a copy of your prescription and a doctor's letter regardless - customs can ask for them even within the allowance. If a month isn't enough, that's when an import certificate (Yunyu Kakunin-sho, still often called Yakkan Shoumei) comes into play; the mechanics of applying for one are covered in bringing prescription medication to Japan.

Japan's free-access system means there's no gatekeeper GP - you can go to a neurologist or general clinic directly, often same-day or within a few days. The first visit involves a medical questionnaire (問診票), so bring your migraine and medication history in writing, including what triptan and dose you've used. The doctor writes the shohosen, and any dispensing pharmacy in Japan can fill it, though calling ahead is sensible since not every pharmacy stocks every drug. Use the pharmacy finder to check nearby pharmacies with verified English-language support, or start with an English-speaking doctor in Tokyo for the clinic side.

Do this before you're out of medication, not during an attack. A standard prescription is valid only 4 days including the issue day, weekends and holidays counted, so getting established isn't about stockpiling - it's about being in a system that can reliably reissue what you need, rather than scrambling for a same-day clinic mid-migraine.
