Pharmacy and Medicine in Japan — What You Can Buy and What to Bring
At some point on a Japan trip, something goes wrong with your body. A cold that started on the plane catches up with you by day three. A stomach that handled everything fine for a week suddenly doesn't. Feet that were fine at home develop blisters by the second day of 20,000 steps. Japan's pharmacies can handle most of this — but only if you know what to look for, because the packaging is almost entirely in Japanese and the product categories don't map cleanly to what you'd reach for at home.
Finding a pharmacy in Japan
Japanese pharmacies come in two forms. Drugstores (ドラッグストア) like Matsumoto Kiyoshi, Sundrug, Welcia, and Tsuruha Drug are the large chain stores — accessible in most commercial areas, stocked with over-the-counter medicines, cosmetics, and snacks. These are where most travelers go. Separate from these are smaller dispensing pharmacies (調剤薬局, chozai yakkyoku) that fill prescriptions — they're attached to clinics and hospitals and are not the right destination for self-treating a common cold.
In tourist areas of Tokyo, Osaka, and Kyoto, Matsumoto Kiyoshi is the most visible chain and the easiest to navigate — some locations near major tourist corridors stock limited English labeling or have multilingual staff. Outside tourist areas, expect Japanese-only packaging across the board.
How Japanese pharmacies are organized — why some medicines are behind the counter
Japan classifies over-the-counter medicines into three categories that determine where they're displayed and how you can buy them. This explains why some products are on open shelves while others require finding a staff member.
Class 1 (第1類医薬品): the highest-risk OTC medicines — including stronger hair loss treatments and some stomach acid medications. These must be sold by a licensed pharmacist after a brief consultation. They're kept behind the counter or in a locked case. You'll need to ask a staff member and answer a few questions before purchase. Look for the yellow "第1類" label.
Class 2 (第2類医薬品): most common cold medicines, pain relievers, and allergy medications fall here. These can be self-selected from the shelf but the store is supposed to offer pharmacist guidance. In practice at busy chain drugstores, you can usually just pick them up and pay. Red "第2類" label.
Class 3 (第3類医薬品): lower-risk products — vitamins, mild digestive aids, eye drops. Freely self-selectable, no consultation required. White or green label.
For most common travel ailments (cold, pain, stomach upset), you're looking at Class 2 products on open shelves. If you can't find what you need on the shelf, ask a staff member — they may need to retrieve a Class 1 product or point you to a specific section.
What you can actually buy over the counter
Some medications that are prescription-only elsewhere are available OTC in Japan. Others that are freely available at home require a pharmacist consultation in Japan. The category that catches most travelers off guard: stronger allergy and cold medications.
Cold and flu (cough, runny nose, sore throat): PaburonS, Lulu, or Benza Block — these are the main Japanese cold medicine brands. They work. Packaging has multiple variants; the standard (no letter suffix) or "Gold" versions are the most general-purpose.
Fever and pain relief: Bufferin (ibuprofen) and Calonal A (カロナールA, acetaminophen/paracetamol, released as OTC in January 2024) are available at drugstores. Note: the original Calonal (カロナール錠) is a prescription drug — the OTC version is specifically Calonal A. If you can't find it, ask for Tylenol (タイレノール) or any product labeled アセトアミノフェン (acetaminophen). EVE is another popular ibuprofen brand.
Stomach issues (nausea, upset stomach): Seirogan is the classic Japanese remedy for stomach upset — small dark pellets, strong smell, effective. For motion sickness, Travamin is widely available.
Diarrhea: Stoppa or Roast — look for these names at the pharmacy counter. More effective options may require asking the pharmacist directly.
Constipation: Colac and similar products are available without consultation.
Antihistamines / allergy: Allegra (fexofenadine) and Claritin (loratadine) are available OTC in Japan at doses equivalent to prescription strength in some countries. This is one area where Japan's OTC availability is actually broader than home for many travelers.
Eye drops: Japan has an unusually wide selection of eye drops — Rohto and Santen are the main brands, with many variants. The cool/refreshing variants are a strong sensation; the standard variants are milder.
Blister and foot care: Compeed-equivalent hydrocolloid bandages are available, often labeled as "moist healing" bandages. Ask for キズパワーパッド (kizu power pad) — these are the hydrocolloid type that actually heal blisters rather than just covering them.
What's harder to find or not available
Some medications common in English-speaking countries either don't exist in Japan under the same formulation or require a prescription.
Pseudoephedrine (Sudafed): not available OTC in Japan. If you rely on pseudoephedrine-based decongestants for sinus congestion, bring your own supply. Japanese cold medicines use different active ingredients.
Codeine-based cough suppressants: Japan classifies codeine differently. Some products containing codeine available OTC in Australia, Canada, and the UK are not available in Japan and may be subject to import restrictions.
High-dose ibuprofen: Japanese OTC ibuprofen doses are lower than what's standard in some countries. 200mg tablets are typical; the 400mg single-dose that's standard in the UK requires more tablets to achieve the equivalent dose.
Prescription medications you take regularly: Japan cannot fill foreign prescriptions. If you take any prescription medication regularly, bring your entire supply plus extra, along with documentation from your doctor. Customs regulations allow bringing personal-use quantities of most medications — check Japan Customs guidelines for controlled substances specifically.
Bringing medications into Japan — what to know
Most standard medications can be brought into Japan for personal use without special procedures — typically up to a one-month supply for prescription drugs and a two-month supply for over-the-counter medicines. Exceptions exist:
Stimulant medications (ADHD medications — Adderall, Ritalin/methylphenidate): Adderall is illegal in Japan regardless of prescription. Ritalin and other methylphenidate-based medications require a special import certificate (Yunyu Kakuninsho) obtained before arrival from the Japanese Embassy in your home country. This is not optional — bringing ADHD stimulant medication without the certificate is a serious legal issue.
Codeine products: some formulations are controlled. Check the Japan Ministry of Health guidelines for your specific medication.
Inhalers: standard asthma inhalers (salbutamol/albuterol, steroid inhalers) are generally permitted with documentation. Bring your prescription.
Needles and syringes (insulin): permitted with documentation (doctor's letter confirming medical need). Declare at customs.
Quantity limits: prescription medications up to 1 month's supply; OTC medications up to 2 months' supply for most categories. Cosmetics and quasi-drugs (some vitamins, topicals) have separate quantity limits.
Communicating at the pharmacy
Most pharmacy staff in Japan don't speak English fluently, but they're accustomed to navigating with international visitors. The most useful approach: show the staff what you're looking for on your phone — a photo of the medication from home, or a Google Images search of the Japanese equivalent. Pointing at a body part and miming a symptom works better than it sounds for simple situations.
A few phrases worth knowing:
「頭痛薬はありますか？」(Zutsuyaku wa arimasu ka?) — "Do you have headache medicine?"
「胃薬はありますか？」(Igusuri wa arimasu ka?) — "Do you have stomach medicine?"
「風邪薬はありますか？」(Kazegusuri wa arimasu ka?) — "Do you have cold medicine?"
For anything more complex, the Japan Visitor Hotline (050-3816-2787, available 24 hours in English) can help with medical situations including pharmacy navigation.
What to pack from home
The honest answer is that Japan's pharmacies are good enough that you don't need to overpack medications. A few things are genuinely worth bringing because they're either unavailable or significantly different in Japan:
Pseudoephedrine-based decongestants if you rely on them. Your prescription medications — full supply plus at least a week extra. Pain relievers at your preferred dose, if you use higher-strength ibuprofen regularly. Any medication for a specific chronic condition. A written list of your medications with generic names (not just brand names) in case you need medical attention in Japan.
Everything else — standard pain relievers, antihistamines, stomach remedies, blister care — Japan handles well. Packing a large first-aid kit "just in case" adds weight without adding meaningful security given the pharmacy density in Japanese cities.
