Drugstore Basics in Japan: How to Buy OTC Medicine Safely

Buying medicine in Japan can be confusing if you do not read Japanese. Drugstores are easy to find, but medicine names, labels, sales rules, and pharmacist availability may be different from your home country.

This guide is for travelers and foreign residents in Japan. It explains where to buy OTC medicine, what to check before using it, and when to ask a pharmacist, qualified staff such as a registered seller, or a medical professional.

This guide is about buying non-prescription medicine inside Japan. Rules for bringing medicine into Japan from another country are a separate topic and may involve customs or import restrictions.

This article is for general information only. It does not replace medical advice, diagnosis, or treatment. If your symptoms are severe, unusual, or getting worse, please seek medical care.

At a Glance: 3 Steps Before Buying OTC Medicine

If you are in a hurry, start with these three steps:

Step	What to Do	Why It Matters
1	Choose the right place	A drugstore or pharmacy can help with OTC medicine. Severe symptoms may need a clinic or hospital.
2	Check who will use it	Age, pregnancy, breastfeeding, chronic illness, allergies, and other medicines can change what is safe.
3	Check the label before taking it	Look at the active ingredient, dose, age limit, warnings, and possible duplicate ingredients.

If the symptoms are severe, unusual, or getting worse, do not rely only on OTC medicine.

Quick Checklist: Before You Buy or Take Medicine

Before buying or taking OTC medicine in Japan, check:

• Who will use this medicine?
• What is the active ingredient?
• Is it for the right symptom?
• Is it OK for the user’s age?
• What is the dose and maximum daily dose?
• Are there warnings for pregnancy, breastfeeding, illness, allergies, or other medicines?
• Has the user already taken another medicine with the same or similar ingredient?
• Is pharmacist support needed?

If your symptoms are severe, unusual, getting worse, or not improving, OTC medicine may not be enough. See our guide: How to See a Doctor in Japan as a Traveler.

If you are buying medicine for cold-like symptoms, read our cold medicine guide: Cold Medicine in Japan: What to Check Before Buying OTC Medicine.

If your main symptoms are runny nose, sneezing, nasal congestion, or allergy-like symptoms, read our guide: Runny Nose and Allergy Medicine in Japan: Antihistamines, Nasal Sprays, and Decongestants.

During hot and humid weather, fever-like symptoms may be related to heat illness rather than a cold. Read our guide: Heat Illness in Japan: What Travelers Should Check Before Taking Fever Medicine.

Drugstore, Pharmacy, or Clinic? Where to Go First

In Japan, a drugstore usually sells OTC medicines, daily goods, cosmetics, and other health products. Many drugstores are easy to find in cities, near train stations, and in shopping areas.

A dispensing pharmacy mainly handles prescription medicines. Some drugstores also have a dispensing pharmacy counter inside or nearby. If you have a prescription from a Japanese medical institution, you usually take it to a dispensing pharmacy.

If you have mild symptoms and want to ask about OTC medicine, a drugstore or pharmacy may be a good first place to ask. If your symptoms are severe, unusual, or getting worse, go to a clinic or hospital instead of relying only on OTC medicine.

Situation	Where to Go
Mild symptoms and you want OTC medicine	Drugstore or pharmacy
You have a prescription	Dispensing pharmacy
You want a medicine that requires pharmacist explanation	Drugstore or pharmacy with a pharmacist available
Symptoms are severe, unusual, or getting worse	Clinic or hospital
Emergency	Call 119

Do not rely on convenience stores for medicine. Some convenience stores sell limited OTC medicines if qualified staff and the required sales system are available, but many do not. If you are unsure, look for a drugstore or pharmacy.

What You Can Usually Buy at a Japanese Drugstore

Japanese drugstores often sell OTC medicines for common mild symptoms. The exact products vary by store, location, and staff availability.

Common categories include:

• fever and pain medicines
• cold medicines
• stomach and digestive medicines
• allergy medicines
• cough and throat products
• eye drops
• topical products for skin, pain, or itching
• bandages and first-aid supplies

If you are looking specifically for stomach or digestive medicine, you may also want to read our guide: Stomach and Digestive Problems in Japan: OTC Medicine Ingredients and Safety Checks.

This article does not recommend specific products. In Japan, it is safer to choose medicine by active ingredient and safety information, not only by product name or package design.

Remember: not every health product in a Japanese drugstore is an OTC medicine. Some products are quasi-drugs, supplements, cosmetics, or daily goods. If you need medicine for symptoms, check the product category and ask staff if you are unsure.

Prescription Medicines Are Different

OTC medicine means medicine that can be purchased without a prescription under Japanese rules. Prescription medicines are different. You usually need a prescription from a doctor in Japan to receive prescription medicine at a dispensing pharmacy.

If you need a medicine that you usually use in your home country, do not assume the same product, dose, or ingredient is available as OTC medicine in Japan. Ask a pharmacist or see a doctor if you are unsure.

Why Some Medicines Require Pharmacist or Staff Confirmation

In Japan, non-prescription medicines are not all treated the same way. Some medicines have a higher need for safety checks, information, or confirmation at the time of purchase.

This means a drugstore may be open even when some medicines cannot be sold. For example, some medicines require pharmacist involvement and may not be available if the pharmacist counter is closed.

Some products may also require staff to confirm age, quantity, symptoms, or intended use because of safety or misuse concerns. If staff ask questions before selling a medicine, it is usually part of Japan’s medicine safety system.

Medicine Labels You May See in Japan

You do not need to memorize Japan’s medicine categories. The important point is to understand that some products require a pharmacist, while many OTC medicines can be handled by a pharmacist or registered seller.

A registered seller is a qualified medicine sales professional in Japan. Registered sellers can sell many OTC medicines, but they are not the same as pharmacists. If you specifically need to talk to a pharmacist, ask whether one is available.

Here are labels you may see:

Label You May See	Simple Meaning
Guidance-required medicine / 要指導医薬品	Requires pharmacist guidance. Ask the pharmacist.
Class 1 OTC medicine / 第1類医薬品	Requires information from a pharmacist at purchase.
Designated Class 2 OTC medicine / 指定第2類医薬品	A Class 2 medicine that needs extra caution. Ask qualified staff if unsure.
Class 2 OTC medicine / 第2類医薬品	Can be sold by a pharmacist or registered seller. Check warnings carefully.
Class 3 OTC medicine / 第3類医薬品	Can be sold by a pharmacist or registered seller. Generally a lower-risk OTC category, but label checks are still important.

If you see these labels and do not understand them, ask the pharmacist or qualified staff before buying the medicine.

Is a pharmacist available now?

What to Check Before Buying Japanese OTC Medicine

Before you buy or take OTC medicine in Japan, check the package carefully. If you cannot read the label, ask a pharmacist or qualified staff.

Start with this question:

Who will use this medicine?

For example, check whether the medicine is for:

• yourself
• another adult
• a child
• an elderly person
• someone who is pregnant or breastfeeding
• someone with a chronic condition
• someone who takes other medicines

Then check:

• active ingredient
• what symptoms the medicine is for
• age limit
• dose per use
• dosing interval
• maximum daily dose
• warnings and contraindications
• pregnancy or breastfeeding warnings
• chronic illness warnings
• allergy warnings
• possible overlap with medicines already taken

Do not choose Japanese OTC medicine only by product name. Different products can contain the same active ingredient, and similar-looking products may contain different ingredients.

Translation apps can help, but do not rely only on automatic translation for safety-critical information such as dose, age limits, warnings, or duplicate ingredients.

Be Careful With Combination Cold Medicines

Many Japanese cold medicines contain several ingredients in one product. A cold medicine may include ingredients for fever, pain, cough, runny nose, or other symptoms.

For this reason, do not combine OTC cold medicine with fever medicine, pain medicine, allergy medicine, or another cold medicine on your own. You may accidentally take the same or similar ingredients twice.

If you already took a medicine and want to take another one, show the package, photo, or ingredient list to a pharmacist or qualified staff.

When to Ask a Pharmacist

For the situations below, try to speak with a pharmacist if one is available. If a pharmacist is not available, ask qualified staff and consider medical care when needed.

Be especially careful if:

• the medicine is for a child
• the medicine is for an elderly person
• you are pregnant or breastfeeding
• you have stomach or duodenal ulcers
• you have kidney, liver, or heart disease
• you have asthma or medicine allergies
• you have glaucoma or prostate problems
• you take prescription medicines or regular medicines
• you take blood thinners, steroids, sleeping pills, antidepressants, other pain relievers, or other cold medicines
• you are not sure what ingredient is in the product
• you already took another medicine
• symptoms are not improving

Many adult OTC medicines in Japan are not for children. Do not guess the dose from an adult product.

You do not need perfect English or Japanese. Short, clear phrases are enough. You can also show your medicine package, prescription, medication list, or allergy information.

Useful Phrase Examples at a Japanese Drugstore

These are example phrases you can show to staff or a pharmacist. Choose the phrase that matches your situation.

Is a pharmacist available now?

I am looking for OTC medicine for this symptom.

Who can use this medicine?

Is this medicine OK for an adult / a child / an elderly person?

Is this medicine OK during pregnancy or breastfeeding?

Can I take this medicine with my current medicine?

I already took this medicine. Can I take this one too?

Does this medicine contain any ingredient I already took?

Does this medicine contain acetaminophen, ibuprofen, or loxoprofen?

I have allergies. Is this medicine OK for me?

I have asthma / kidney disease / liver disease / a stomach ulcer. Is this medicine OK for me?

When OTC Medicine Is Not Enough

OTC medicine can help with some mild symptoms, but it is not always the right answer. Do not use OTC medicine to delay medical care when symptoms may be serious.

Consider medical care if symptoms are severe, unusual, getting worse, or not improving. Be especially careful with shortness of breath, chest pain, confusion, fainting, severe allergic reaction, severe headache, stiff neck, severe abdominal pain, repeated vomiting, dehydration, severe weakness, or symptoms after heat exposure.

If you may be having a medical emergency in Japan, call 119 for an ambulance.
