Where to Buy
Understanding where to shop matters in Japan because product availability varies significantly by store type.
Best option for tourists: Major drugstore chains
The three largest drugstore chains in Japan — Matsumoto Kiyoshi (マツモトキヨシ), Sundrug (サンドラッグ), and Tsuruha Drug (ツルハドラッグ) — have extensive product ranges and are found in virtually every tourist area. Matsumoto Kiyoshi in particular has many bilingual staff in major tourist districts (Shinjuku, Akihabara, Dotonbori).
For Class 1 drugs (第1類医薬品) like Loxonin S, you must ask at the counter — these are kept behind the pharmacist's desk. Show the pharmacist the product name in Japanese and they will assist you.
Convenience stores carry some basic sore throat products, including standard throat lozenges and occasionally simple antiseptic spray. They are not a reliable option for pharmaceutical-grade products.
How to Ask for Sore Throat Medicine
Japanese pharmacy staff are generally helpful, but do not rely on a translation app in real time — connection issues and inaccurate translations can cause confusion. Use these prepared phrases instead:
Showing the Japanese text on your phone is often more reliable than attempting pronunciation. Most pharmacy staff will recognize what you need.
Note on translation devices: Pocket translation devices and general-purpose translation apps have poor accuracy for medical and pharmaceutical terminology. English-speaking pharmacists are available at some locations in major tourist areas, but cannot be guaranteed. Preparing written Japanese phrases in advance is far more reliable.
When to See a Doctor Instead
OTC medicines are appropriate for mild-to-moderate sore throats without high fever or alarming symptoms. However, certain signs indicate that a throat infection may require prescription treatment.
See a doctor if:
- Your sore throat has lasted more than 3 days without improvement
- You have a high fever (38.5°C / 101.3°F or above)
- You are unable to swallow liquids or your own saliva
- You have visible white patches or pus on your tonsils
- You have swollen, tender lymph nodes in your neck
- You have difficulty breathing or a muffled voice
- The pain is one-sided (possible peritonsillar abscess)
- You are immunocompromised, diabetic, or have a chronic condition
Streptococcal pharyngitis ("strep throat") and bacterial tonsillitis require antibiotic treatment — OTC products will not resolve these infections. Peritonsillar abscess is a medical emergency.
Japan has excellent ENT (ear, nose, and throat) clinics. You can find an ENT clinic near you using our medical facility search. Many large cities have clinics with English-speaking staff or multilingual support.

Cost Comparison Table
Japan's OTC medicine prices are generally moderate. All prices below are approximate retail prices (JPY) at major drugstore chains as of 2024–2025.
For context, a visit to an ENT clinic in Japan typically costs ¥2,000–¥5,000 without insurance (and less with travel insurance). If your sore throat is potentially bacterial, a clinic visit is cost-effective and will yield faster resolution than OTC treatment alone.
FAQ
Q: Can I find English-language instructions for throat medicine in Japan?
A: Most OTC product packaging in Japan is in Japanese only. The large chains — Matsumoto Kiyoshi, Sundrug — sometimes have multilingual product guides near the pharmacy counter in tourist-heavy areas. Your best strategy is to bring the Japanese product names from this article to the drugstore. Some pharmacists in tourist areas speak English.
Q: Is strep throat common in Japan?
A: Yes. Group A streptococcal pharyngitis (*yōrenkin ensen*, 溶連菌咽頭炎) is a routine diagnosis at ENT and internal medicine clinics in Japan. Rapid strep tests are available. If you suspect strep — high fever, severe throat pain, no cough, visible pus — see a doctor rather than treating with OTC medicine.
Q: Can I buy antibiotics over the counter in Japan for a sore throat?
A: No. Antibiotics require a prescription in Japan without exception. OTC products are for symptomatic relief only. If you need antibiotics (e.g., for confirmed strep throat), you must visit a clinic.
Q: Is Loxonin S safe to take with other medicines I brought from home?
A: Loxoprofen (Loxonin S) is an NSAID and should not be combined with other NSAIDs (ibuprofen, naproxen, aspirin), blood thinners, or certain blood pressure medications. Disclose all current medications to the pharmacist when purchasing. People with stomach ulcers, kidney disease, or who are pregnant should avoid NSAIDs entirely.
Q: Are Japanese throat lozenges stronger than Western products?
A: Medicated lozenges in Japan are broadly comparable to equivalent products elsewhere. The difference is mainly in formulation — many Japanese products combine IPMP (a potent antiseptic not common in Western lozenges) with soothing agents and local anaesthetics. The combination can feel more effective than simple menthol lozenges.
Q: Can children use these products?
A: Most medicated throat products have minimum age requirements printed on the packaging (often 15 or 18 for adult products). For children, show the pharmacist the child's age — they will direct you to age-appropriate options. Ibuprofen-based products should not be given to children under 6 months; aspirin should be avoided entirely in children under 15 with viral illness (risk of Reye's syndrome).
Q: What if my sore throat doesn't improve after 3 days of OTC treatment?
A: See a doctor. A sore throat persisting beyond 3 days with OTC medicine may indicate a bacterial infection requiring antibiotics, or a different underlying cause. Use our ENT clinic finder to locate nearby clinics, many of which accept walk-ins.
