Stomach Pain in Tokyo? What to Do Right Now

Stomach pain while traveling can be hard to judge — is it something you ate, or something more serious? Most stomach pain in travelers is mild and settles on its own.

This page helps you decide what to do next — rest at your hotel, arrange a same-day doctor visit, or seek emergency care. TOKYO CLINIC sends English-speaking doctors directly to your hotel in central Tokyo, usually within 60–90 minutes.

What Should I Do Now?

Mild, intermittent discomfort Rest, a bland diet, and fluids — monitor for 24 hours.
Persistent pain with nausea, vomiting, or diarrhea Arrange a same-day medical assessment — message us on WhatsApp and a doctor can visit your hotel.
Severe pain, especially lower-right abdomen, or blood in vomit/stool Call 119 immediately, or ask hotel staff to call for you.

When Should I Seek Emergency Care?

Call 119 for an ambulance (or ask hotel staff to call) if your stomach pain comes with any of the following:

  • Severe, worsening pain — especially in the lower right abdomen
  • Pain so severe you cannot stand up straight or move without discomfort
  • A rigid, hard abdomen
  • Vomiting blood, or vomit that looks like coffee grounds
  • Black, tarry stools, or visible blood in your stool
  • High fever with chills and severe pain

Can I Stay in My Hotel?

If none of the emergency signs above apply, you can usually stay at your hotel while a doctor examines and treats your stomach pain. If your symptoms suddenly get worse, or you notice any of the emergency signs above — even while you're waiting for the doctor — call 119 right away rather than wait for us. TOKYO CLINIC is here to help with non-emergency care; it should never delay emergency treatment.

Common Causes of Stomach Pain

  • Food poisoning / gastroenteritis — from a change in food or water; common among travelers.
  • Indigestion or overeating — unfamiliar food, large meals, or alcohol.
  • Traveler's diarrhea — often comes with cramping abdominal pain.
  • Stress or jet lag — can worsen digestive symptoms while traveling.
  • Constipation — from dehydration, less fiber, or a change in routine.
  • Menstrual cramps — for travelers who are menstruating.

How Stomach Pain Is Assessed

  • History — location, timing, and severity of pain, food/water exposure, medications, in English.
  • Examination — abdominal exam, temperature, and vital signs.
  • Additional testing — performed in your room when appropriate.
  • Clear explanation — the doctor explains the likely cause and what it means for your trip.

Possible Treatment

  • Symptom relief — medication for pain, nausea, or cramping.
  • Rest and dietary advice — a bland diet and hydration for most mild cases.
  • Antibiotics — only when a bacterial infection is confirmed.
  • Hospital referral — if a more serious condition, such as appendicitis, is suspected.

Frequently Asked Questions

Is it something I ate?

Often, yes — a change in food or water is one of the most common causes of stomach pain in travelers. The doctor can help confirm the cause and advise on treatment.

Do I need antibiotics?

Only if a bacterial infection is confirmed. Most travelers' stomach pain is caused by diet, stress, or a mild viral illness, and antibiotics won't help in that case.

Can I fly tomorrow?

Often yes, if your pain is mild and improving with no red-flag symptoms. The doctor can advise based on your specific case and provide documentation if needed.

Can I get a medical certificate?

Yes, for travel insurance claims or airline documentation.

Will the doctor speak English?

Yes. All doctors seeing international patients are English-speaking, from first contact to the visit itself.

Should I go to a hospital?

Not usually. Most stomach pain can be safely assessed and treated at your hotel. A hospital referral is arranged only if your condition needs care beyond a house call, such as suspected appendicitis.
