Checked on August 27, 2026. Buying medicine in Japan is manageable, but a familiar brand name from home may have different ingredients—or may not be sold at all. The safest approach is to describe your symptoms, current medicines, allergies and medical conditions to a pharmacist instead of choosing by package design.
This guide explains where to go, what to bring, how Japanese prescriptions work, and when medicine carried from overseas needs advance permission. It is practical travel information, not a diagnosis or a substitute for medical care.
Drugstore, pharmacy or clinic: which one do you need?
- Drugstore (ドラッグストア): sells toiletries, cosmetics and many over-the-counter products. Some medicines can only be sold while a pharmacist or registered seller is present, so the medicine counter may close before the store.
- Dispensing pharmacy (調剤薬局): fills prescriptions issued in Japan. Look for “処方せん” or ask at a clinic where the nearest dispensing pharmacy is.
- Clinic or hospital: use this when symptoms are severe, worsening, recurring, involve breathing difficulty or significant pain, or when you need a prescription medicine. A pharmacy cannot replace an examination.
A safe step-by-step way to buy OTC medicine
- Write down the active ingredients in medicines you already take. A photo of the front label alone is often insufficient.
- Describe the main symptom and duration: fever, cough, pain, diarrhea, rash, and how long it has lasted.
- State allergies, pregnancy, age and medical conditions, especially liver or kidney disease, asthma, glaucoma, high blood pressure or stomach ulcers.
- Ask about duplicate ingredients. Multi-symptom cold products may overlap with painkillers, antihistamines or cough medicines.
- Confirm the dose and maximum daily amount before leaving. Package instructions are usually in Japanese.
- Keep the box and leaflet in case you need a doctor later.

Why the same-looking product may not be equivalent
Product names, strengths and approved uses vary by country. Two boxes marketed for “cold symptoms” can contain different combinations. Do not match only by color, brand or translated product name. Ask staff to compare active ingredients and dose. The Pharmaceuticals and Medical Devices Agency (PMDA) provides an official search for Japanese OTC package inserts, although much of the database is in Japanese.
How prescriptions work in Japan
A prescription issued by a Japanese medical institution may be filled at an in-hospital pharmacy or an outside dispensing pharmacy, depending on the provider. Bring the prescription, identification and any medication record you have. An overseas prescription is useful medical information, but travelers should not assume that it can be directly filled in Japan; a Japanese clinician may need to examine you and issue a local prescription.
Ask the clinic about payment and language support before the consultation. Travel insurance may require an itemized receipt or medical certificate, so keep every document.
Bringing your own medicine into Japan
The Ministry of Health, Labour and Welfare (MHLW) says that an Import Confirmation is generally not required when medicines for personal use remain within specified quantities. The current official English guidance lists up to one month’s supply for prescription drugs, poisons or deadly poisons; up to two months’ supply for other drugs and quasi-drugs; up to 24 units per item for certain external-use products; and up to one month’s supply for eligible self-injection products with their pre-filled syringe or self-injection kit.
These quantity limits do not override controls on narcotics, stimulants, stimulant raw materials or other prohibited and controlled substances. Rules depend on the ingredient, not only the product name or whether it is legal in your home country. If your medicine is controlled, exceeds the listed quantity, or uses an injection device, check the MHLW and Narcotics Control Department pages well before departure. Some Import Confirmation applications can be submitted online.
Packing medicines for immigration and emergencies
- Keep medicine in the original labeled container.
- Carry a copy of the prescription or doctor’s letter showing generic ingredient names, dosage and medical need.
- Pack essential medicine in hand luggage while following airline liquid and security rules.
- Bring only medicine for your own use. Official guidance does not permit selling or giving personally imported medicine to others.
- Do not post extra medicine to Japan without checking the import rules; mailed products are also regulated.
When to stop self-treating
Seek medical help rather than repeatedly buying OTC products if symptoms are severe, rapidly worsening, persist beyond the period stated on the package, or include breathing difficulty, fainting, confusion, serious dehydration, a severe allergic reaction, chest pain or signs of stroke. For an ambulance in Japan, call 119. If you are unsure whether a clinic visit is needed, hotel staff, travel insurance assistance or an official visitor support service may help you locate care.
FAQ
Are Japanese drugstores open 24 hours?
Some are, but medicine sales can be limited to hours when qualified staff are present. Check the pharmacy counter hours, not only the building’s opening hours.
Can I buy antibiotics over the counter?
Do not expect to. Medicines requiring a prescription need assessment and a valid Japanese prescription. A pharmacist can tell you whether an OTC option is appropriate for symptom relief or whether you should see a doctor.
Can I bring a one-month supply of any prescription medicine?
No. The one-month quantity exemption is not permission for every ingredient. Controlled or prohibited substances follow separate rules, and some medicines need advance procedures regardless of ordinary quantity guidance.
Should I use a translation app?
Yes, but also show the original ingredient list, prescription or doctor’s letter. Machine translation can confuse product names and dosage instructions, so confirm the final choice with qualified staff.
