You’re in the middle of your Japan trip when you realize your medication is gone — lost in a cab, left at the hotel, stolen, or simply used up faster than expected. It’s a stressful moment, and knowing what to do next isn’t obvious when you’re in a foreign country with a different medical system.
\\n\\n\\n\\nLast updated: March 2026. Medically reviewed by the medical team at SAKURA International Clinic Asakusa.
\\n\\n\\n\\n\\nThe good news: you have options. The bad news: you need to act quickly and understand a few key rules about how Japan handles foreign prescriptions. This guide walks you through everything step by step.
\\n\\n\\n\\nFrequently Asked Questions
\\n\\n\\n\\nCan a Japanese doctor prescribe my regular medication?
\\n\\n\\n\\nYes, a Japanese doctor can prescribe equivalent medications if you provide details about your current prescription — including the drug name (generic preferred), dosage, and frequency. Bring any documentation you have: empty packaging, pharmacy labels, or a photo of your prescription. Some medications available abroad may be restricted in Japan.
\\n\\n\\n\\nWhat medications are banned in Japan?
\\n\\n\\n\\nStimulant-based medications containing amphetamines — including Adderall — are strictly prohibited in Japan, even with a valid foreign prescription. Codeine-containing products above certain thresholds and some pseudoephedrine formulations also face restrictions. Bring a copy of your prescription and check Japan Customs regulations before traveling.
\\n\\n\\n\\nHow do I get emergency medication in Japan without a prescription?
\\n\\n\\n\\nVisit a clinic for a same-day consultation — most can prescribe essential medications immediately. For after-hours emergencies, hospital emergency departments can provide critical medications. Some medications like asthma inhalers and insulin may be dispensed by hospital pharmacies in urgent situations without the usual clinic visit process.
\\n\\n\\n\\nCan I bring a 90-day supply of medication to Japan?
\\n\\n\\n\\nYou can bring up to a 1-month supply of most prescription medications into Japan without special documentation. For supplies exceeding 1 month (up to 4 months), you need a “Yakkan Shoumei” import certificate from the Ministry of Health. Apply at least 2 weeks before travel through the Regional Bureau of Health and Welfare.
\\n\\n\\n\\nHow much does a prescription cost in Japan without insurance?
\\n\\n\\n\\nWithout Japanese health insurance, a clinic consultation costs ¥5,000–¥10,000 and prescription medications cost ¥1,000–¥10,000 depending on the drug. Common medications like blood pressure pills or antibiotics are relatively affordable at ¥1,000–¥3,000. Specialty medications can be significantly more expensive. Keep receipts for travel insurance reimbursement.
\\n\\n\\n\\nForeign Prescriptions Are Not Valid in Japan
\\n\\n\\n\\nThis is the most important thing to understand before you walk into a Japanese pharmacy: Japan does not accept foreign prescriptions. It doesn’t matter if your prescription is from the United States, the UK, Australia, or anywhere else. Japanese pharmacies are legally prohibited from dispensing medication based on overseas prescriptions.
\\n\\n\\n\\nThis surprises a lot of travelers. You might assume that showing a valid, unexpired prescription from your home country would be enough to get a refill. Unfortunately, that’s not how the Japanese healthcare system works.
\\n\\n\\n\\nTo obtain prescription medication in Japan, you need a prescription written by a licensed Japanese physician. There are no exceptions. Even if you’ve been on the same medication for years, you’ll need to see a doctor here first.
\\n\\n\\n\\nThe process isn’t as daunting as it sounds — especially if you visit a clinic with English-speaking doctors. But understanding this rule upfront saves you from wasting time at pharmacies that simply cannot help you without the right paperwork.
\\n\\n\\n\\nMedications That Are Restricted or Banned in Japan
\\n\\n\\n\\nJapan has strict drug laws, and several medications that are completely legal and commonly prescribed in other countries are either restricted or outright banned here. If you’ve lost one of these medications, getting a replacement in Japan may be difficult or impossible — even from a Japanese doctor.
\\n\\n\\n\\nHere are the most important categories to know about:
\\n\\n\\n\\nStimulant ADHD Medications
\\n\\n\\n\\nAdderall (amphetamine salts) is completely illegal in Japan — not just restricted, but banned outright. Possession can result in arrest. If you take Adderall for ADHD, you cannot bring it into Japan and cannot obtain it here. Speak with your doctor before your trip about alternatives such as atomoxetine (Strattera), which is available in Japan.
\\n\\n\\n\\nCodeine-Containing Medications
\\n\\n\\n\\nCodeine is a controlled substance in Japan. Many over-the-counter cough and pain medications from abroad contain codeine and are not permitted. This includes popular products like Tylenol with Codeine, certain UK codeine tablets, and various cough syrups. If you’ve run out of a codeine-containing medication, a Japanese doctor can evaluate your condition and prescribe an appropriate alternative.
\\n\\n\\n\\nPsychotropic and Narcotic Medications
\\n\\n\\n\\nStrong psychotropic medications — including certain benzodiazepines and narcotic painkillers — fall under Japan’s narcotics control laws. You may bring a limited personal supply into Japan, but quantities are restricted, and bringing more than a one-month supply typically requires advance documentation.
\\n\\n\\n\\nYakkan Shoumei: The Import Certificate
\\n\\n\\n\\nIf you need to bring controlled or restricted medications into Japan, you may need a Yakkan Shoumei — an import certificate issued by Japan’s Ministry of Health, Labour and Welfare (MHLW). This must be arranged before you travel, not after you arrive. If you’ve already lost your medication here, this doesn’t apply to your current situation, but it’s essential to know for your next trip.
\\n\\n\\n\\nFor most standard medications — blood pressure drugs, diabetes medications, asthma inhalers, antidepressants — the situation is much simpler, and getting a replacement prescription is straightforward.
\\n\\n\\n\\nHow to Get an Emergency Prescription in Japan
\\n\\n\\n\\nIf you’ve lost medication in Japan and need a refill, the fastest path forward is to visit an English-speaking clinic and see a Japanese-licensed doctor. Here’s how the process works:
\\n\\n\\n\\n- \\n
- Find a clinic with English-speaking doctors. Not all clinics in Japan have English-language capacity. Look specifically for international or foreigner-friendly clinics in major cities. Tokyo has several good options, including SAKURA International Clinic Asakusa. \\n
- Make an appointment or walk in. Many English-friendly clinics accept walk-ins, though appointments can reduce wait time. If your situation is urgent, call ahead and explain that you’ve run out of or lost essential medication. \\n
- See the doctor and explain your situation. The doctor will review your medical history, ask about your condition, and assess what medication is appropriate. Bring as much information as possible about your current prescription (more on that below). \\n
- Receive a Japanese prescription. If the doctor determines the medication is appropriate and available in Japan, they’ll write you a Japanese prescription (処方箋, shohosen). \\n
- Fill the prescription at a pharmacy. Take the prescription to any pharmacy (薬局, yakkyoku). Most hospitals have a pharmacy nearby, and pharmacies are common throughout Japanese cities. \\n

\\n\\n\\n\\nWhat to Bring to Your Doctor’s Visit
\\n\\n\\n\\nThe more information you can give your doctor, the faster and smoother your appointment will be. Even if you’ve lost the medication itself, there are several ways to document what you were taking.
\\n\\n\\n\\nEssential Information to Have Ready
\\n\\n\\n\\n- \\n
- Generic drug name: Brand names vary by country, but generic names (the actual chemical compound) are universal. For example, “atorvastatin” instead of “Lipitor,” or “metformin” instead of “Glucophage.” If you only know the brand name, look it up before your appointment. \\n
- Dosage and frequency: How many milligrams? How many times per day? When during the day do you take it? \\n
- Photos of the medication: If you have photos of the pill, the bottle, or the packaging on your phone, bring those. Even a photo of the label can be very helpful. \\n
- Your medication notebook or medical summary: Some travelers keep a simple document (digital or paper) listing all their current medications, conditions, and allergies. If you have one, this is exactly the moment it was made for. \\n
- Your home country prescription copy: If you have a scanned or photographed copy of your original prescription, bring it. While the Japanese doctor can’t simply honor it, it provides useful reference information. \\n
- Your health insurance card: Japan has universal health insurance, but as a tourist, you likely won’t have Japanese coverage. Bring whatever travel insurance documentation you have. Many clinics can provide receipts for reimbursement claims later. \\n
- Allergy information: Tell your doctor about any known drug allergies, especially if the medication has an equivalent or substitute available. \\n
Don’t worry if you can’t remember every detail — a good doctor will ask the right questions. But the more prepared you are, the better the outcome for you.
\\n\\n\\n\\nCommon Medications and Their Japanese Equivalents
\\n\\n\\n\\nMany medications used around the world have direct equivalents available in Japan. Below are some of the most common categories. Keep in mind that brand names differ, but the active ingredients are often identical.
\\n\\n\\n\\n| Condition | Common Medication Abroad | Japanese Equivalent / Generic Name |
|---|---|---|
| High blood pressure | Lisinopril, Amlodipine, Losartan | Same generic names widely available (e.g., Amlodipine as アムロジピン) |
| Type 2 Diabetes | Metformin, Glipizide, Sitagliptin | Metformin (メトホルミン) and Januvia (Sitagliptin) are available |
| Asthma / COPD | Salbutamol inhaler, Fluticasone, Montelukast | Salbutamol (サルブタモール) inhalers available; Singulair (Montelukast) available |
| Depression / Anxiety | Sertraline (Zoloft), Escitalopram (Lexapro), SSRIs | SSRIs are available in Japan; Paroxetine (Paxil) very common |
| Thyroid (hypothyroid) | Levothyroxine (Synthroid) | Thyradin-S (チラーヂンS) — same active ingredient |
| Cholesterol | Atorvastatin (Lipitor), Rosuvastatin (Crestor) | Both available under generic or brand names |
| Acid reflux / GERD | Omeprazole, Lansoprazole | Omeprazole (オメプラゾール), Takepron (Lansoprazole) widely used |
| Antihistamines | Cetirizine (Zyrtec), Loratadine (Claritin) | Cetirizine (ジルテック) available; Japanese antihistamines also widely stocked OTC |
This table is for general reference only. A Japanese doctor will make the final determination about what’s appropriate and available for your situation. Some medications require additional evaluation before prescribing, even if they are routinely prescribed abroad.
\\n\\n\\n\\nHow to Prevent This from Happening on Your Next Trip
\\n\\n\\n\\nGetting caught without medication in a foreign country is stressful — and entirely avoidable with a little preparation before you travel. Here’s what experienced travelers and medical professionals recommend:
\\n\\n\\n\\nPack More Than You Need
\\n\\n\\n\\nThe golden rule: bring at least 1.5 times your expected supply. If you’re traveling for two weeks, bring three weeks’ worth. This protects you against delays, lost luggage, or an extended stay. Split your supply between your carry-on and checked luggage so losing one bag doesn’t mean losing everything.
\\n\\n\\n\\nCreate a Medication Information Card
\\n\\n\\n\\nBefore you leave home, write up a simple medication card that includes:
\\n\\n\\n\\n- \\n
- Each medication’s generic name \\n
- Dosage and frequency \\n
- The condition it treats \\n
- Any known allergies or drug interactions \\n
- Your doctor’s name and contact information \\n
Store this digitally (in your email or cloud storage) and carry a printed copy. This one document can make an emergency clinic visit significantly easier.
\\n\\n\\n\\nKeep a Copy of Your Prescription
\\n\\n\\n\\nAsk your home doctor for a signed copy of your prescription on letterhead — or photograph the original before you travel. While it won’t be accepted directly in Japan, it provides the exact drug name, dosage, and prescribing doctor’s information that a Japanese physician will want to see.
\\n\\n\\n\\nResearch Before You Travel
\\n\\n\\n\\nIf you take controlled substances, stimulants, or any medication that might be restricted, check Japan’s Ministry of Health website or contact the Japanese Embassy in your country before your trip. For medications requiring a Yakkan Shoumei, the application process takes time — you can’t do it last minute.
\\n\\n\\n\\nKnow Where to Go in an Emergency
\\n\\n\\n\\nBefore your trip, identify an English-speaking clinic in the cities you’ll be visiting. Save the address and phone number in your phone. Knowing exactly where to go — rather than searching in a panic — makes all the difference when something goes wrong.
\\n\\n\\n\\nIf you take medication for a chronic condition and are planning an extended stay, read our guide on managing chronic medication refills in Japan for more detailed information.
