How to Get an Asthma Inhaler in Japan

Getting an asthma inhaler in Japan means seeing a doctor, not visiting a drugstore. Inhalers are prescription medicines here, available through clinics under Japan's system of separating prescribing from dispensing: a doctor writes a shohosen (処方箋), and only a licensed dispensing pharmacy fills it. There's no over-the-counter inhaler tier, no equivalent to walking into a pharmacy abroad and buying Ventolin off the shelf. If you're running low, the practical move is to book a clinic appointment before you run out - Japan's free-access system means you can usually be seen the same day or within a few days, no referral required. Bring the inhaler itself and a letter with the medication's generic name, and use the pharmacy finder to locate a dispensing pharmacy with verified English support near your clinic.

Japan's OTC system is tiered - Guidance-Requiring drugs, Class 1, Class 2, and Class 3 - covering things like cold and pain remedies sold directly by pharmacists or registered sellers. Inhalers don't sit in any of those tiers; like antibiotics, they're prescription-only across the board. That means the drugstore (ドラッグストア) down the street, even a large one with a dispensing counter, can't sell you an inhaler without a shohosen. What it can fill is a prescription written by a Japanese doctor, at a dispensing pharmacy (chozai yakkyoku, 調剤薬局), identified by a sign reading 調剤 or 薬局 and usually a green cross.

If you're arriving in Japan with an existing inhaler, the standard personal import allowances apply: prescription drugs up to a one-month supply without needing an import certificate. Carry a copy of your prescription and a doctor's letter alongside the inhaler, even within that allowance - customs officers may ask, and having documentation ready avoids delay. A prescription written outside Japan can't be filled here, so once your imported supply runs low, you're back to seeing a Japanese doctor for a new shohosen rather than trying to get the original refilled.
