Stomach Pain Doctor in Tokyo
Stomach pain, nausea, or diarrhea can quickly derail a trip. This guide explains common causes, warning signs, and where to find English-speaking medical care for digestive issues in Tokyo.
Common Causes
Traveler’s stomach issues often have one of a few underlying causes. Identifying what’s likely going on can help both you and the doctor decide on next steps.
- Food-related upset. Unfamiliar ingredients, street food, or raw fish can irritate sensitive stomachs even when the food itself is safe.
- Food poisoning. Sudden onset of vomiting or diarrhea within hours of a meal suggests bacterial contamination and warrants medical attention if severe.
- Travel fatigue and stress. Jet lag, dehydration, and long travel days can trigger gastritis-like symptoms.
- Water and diet changes. Sudden shifts in water source or fiber intake can affect digestion for a few days.
When to See a Doctor
Mild stomach upset usually resolves within a day with rest and hydration. See a doctor promptly if you experience any of the following:
- Vomiting or diarrhea lasting more than 24 hours, or severe dehydration signs (dizziness, very dark urine).
- Blood in stool or vomit.
- High fever (above 38.5°C / 101°F) alongside abdominal pain.
- Severe, localized pain — especially in the lower right abdomen.
- Symptoms in children, the elderly, or anyone with a chronic condition.
For severe symptoms or signs of appendicitis, call 119 for an ambulance or go directly to an emergency department.
Where to Go
Several clinics across Tokyo are accustomed to treating international visitors with stomach complaints. Walk-in general practice or internal medicine (naika) clinics are usually the fastest option for non-emergency symptoms.
Shinjuku
As a major transit and hotel hub, Shinjuku has several general clinics offering same-day consultations. Walk-in availability is generally good on weekday mornings.
Shibuya
Shibuya is home to internal medicine clinics accustomed to younger travelers and expats. Many accept credit cards and issue English itemized receipts for insurance claims.
Roppongi
Roppongi hosts several international clinics that cater specifically to tourists, embassies, and long-term foreign residents. English service is often standard here.
Shinagawa
Convenient near the bullet train and Haneda Airport, Shinagawa has general hospitals and clinics that handle febrile illness, including influenza and COVID-19 testing.
Online Consultation
For milder symptoms, an online doctor can help assess whether you need to visit a clinic in person, and suggest over-the-counter options available at Japanese pharmacies.
What to Expect & Cost Guide
A standard stomach consultation typically includes a brief interview, abdominal examination, and — if necessary — a stool sample or basic blood work. Without Japanese health insurance, expect the following rough ranges:
- Initial consultation: approximately ¥5,000 – ¥15,000
- Stool test or basic blood work: approximately ¥3,000 – ¥10,000
- Medication (antiemetics, rehydration, antibiotics if indicated): approximately ¥1,500 – ¥5,000
Bring your travel insurance card. Some insurers have direct-billing arrangements with clinics that cater to international visitors.
