OTC Medicines Available at Japanese Pharmacies
Japanese pharmacies (薬局, *yakkyoku*) — including chains such as Matsumoto Kiyoshi, Sugi Pharmacy, and Welcia — stock a wide range of headache remedies without a prescription.
Loxonin S (loxoprofen sodium) is a popular NSAID similar to ibuprofen. It is effective for tension headaches and mild migraines. Note: not suitable if you have stomach ulcers or kidney issues.
Bufferin and Eve A are acetaminophen/ibuprofen combination products widely available and familiar to Western travelers.
Naron Ace T contains acetaminophen, aspirin, and caffeine — a classic combination for tension headaches.
Seirogan and ginger-based products can help when headaches are accompanied by nausea.
Bring these medicines to the pharmacist counter — many urban pharmacies have English-speaking staff, and you can point to the product or show symptoms on your phone.
Finding a Doctor in Japan
If OTC medicine is not working or you have red-flag symptoms, seek care at an internal medicine clinic (内科, *naika*). For migraines specifically, a neurologist (神経内科, *shinkei naika*) is ideal.
Translation apps and devices have limited accuracy for medical conversations. We strongly recommend using a clinic that offers English-language consultation. You can search for English-speaking internal medicine clinics near you on Traveler's Hospital.
Estimated Costs at a Japanese Clinic
Japan's universal health insurance system covers citizens and long-term residents, but short-stay tourists pay out-of-pocket unless they hold travel insurance. Costs below are approximate for uninsured patients.
Always keep your travel insurance documents and emergency contact numbers handy. Most insurers have 24-hour English hotlines.

FAQ
Q: Can I buy ibuprofen at a Japanese pharmacy?
A: Pure ibuprofen products are available, but branding differs. Ask a pharmacist for "ibuprofen" (イブプロフェン) or look for Eve A or Bufferin — both widely stocked. Loxonin S (loxoprofen, a similar NSAID) is also very accessible.
Q: Is acetaminophen (Tylenol) available in Japan?
A: Yes. Look for "Tylenol" at larger pharmacies or ask for acetaminophen (アセトアミノフェン). Some pharmacies also stock Calonal, a prescription-grade product that pharmacists can dispense.
Q: What does a thunderclap headache feel like and why is it dangerous?
A: A thunderclap headache reaches maximum intensity within 60 seconds and is often described as the worst headache of your life. It can indicate a subarachnoid hemorrhage (bleeding in the brain) — a life-threatening emergency. Call 119 immediately.
Q: Will the hospital in Japan understand my English?
A: Major city hospitals often have interpreters or English-speaking staff, but smaller clinics may not. Translation devices and apps have limited accuracy in medical contexts. Using a clinic listed on Traveler's Hospital — which filters for English-compatible facilities — significantly reduces miscommunication risk.
Q: Can jet lag cause headaches?
A: Yes. Disrupted circadian rhythms affect blood flow and hormone regulation, both of which can trigger headaches. Staying hydrated, adjusting to local time as quickly as possible, and getting natural sunlight during the day all help reduce jet-lag headaches.
Q: Do I need a referral to see a neurologist in Japan?
A: Not always. You can walk in to many neurology clinics directly. However, if you go to a large university hospital without a referral, an additional fee (typically ¥5,000–¥7,700) is charged. Starting at a regular internal medicine clinic and asking for a referral letter is often more cost-effective.
