Prescription for Foreign Visitors in Japan: What the October 2026 Ministry Statement Means for Travelers

Foreign visitors in Japan can receive a prescription when an examining doctor decides that treatment is needed during their stay. As a licensed pharmacist working in Tokyo, I am often asked by travelers about clinic visits, how much medicine they can get, and whether a Japanese prescription can cover them after they fly home. A recent statement from Japan's Minister of Health, Labour and Welfare makes the answer clearer: a prescription in Japan is meant to cover your time in Japan, and ongoing treatment belongs with your own doctor at home.

What the Health Minister Said About Prescriptions for Foreign Visitors

On October 9, 2026, the Minister of Health, Labour and Welfare was asked about foreign visitors seeking prescriptions in Japan for medicines such as Mounjaro to take back to their home countries. The minister said that when doctors prescribe for foreign travelers, the appropriate amount is what the patient needs during their stay in Japan. Prescribing a large quantity intended for use after returning home is not appropriate from a medical safety perspective.

The reasoning is practical. In a single visit, a doctor in Japan has limited access to a traveler's full medical history and long-term treatment. Safe treatment depends on continued follow-up, so travelers should see their regular doctor once they return home.

One point matters for travelers: this is the minister's stated view, not a new law or a fixed limit in days. The minister said there were no plans to issue a formal notice at that time. Doctors in Japan still decide case by case, and the statement does not guarantee or rule out a prescription for any individual visitor. The full summary of the press conference is published on the Ministry of Health, Labour and Welfare website (Japanese).

Why Japanese Prescriptions Focus on Your Stay

When a visitor walks into a clinic in Tokyo or Kyoto, the doctor evaluates what is happening now: a sudden illness, or short-term support for an existing condition while traveling.

A single outpatient visit cannot replace ongoing care. Some prescription medicines, including those that affect metabolism or hormones, need regular lab tests, blood pressure checks, and dose adjustments. If a visitor received several months of medicine during a short trip, the prescribing doctor in Japan could not watch for side effects or check whether the dose still fits after the visitor flies home.

This is why the minister described travel prescriptions as covering your stay, not your life after it. The goal is to keep you well while you are here. If you live in Japan and have Japanese health insurance, the system has its own pathways for ongoing treatment, covered in my guide to prescription refill in Japan. For tourists and business travelers, ongoing care stays with your doctor at home.

Getting a Prescription in Japan Is Different From Bringing Medicine In

Many travelers mix up two separate things: bringing their own medicine into Japan, and getting a prescription after they arrive. They follow different rules.

When you pack prescription medicine before departure, Japanese personal import rules apply, and the limits depend on the type of medicine. Some categories need approval before you fly. The details are in my guide on bringing your medication to Japan, and my separate guide on whether you can bring Mounjaro to Japan.

Getting a prescription after you land is a domestic healthcare process. A pharmacy in Japan cannot fill a prescription from your home country, on paper or digital. Pharmacists in Japan can only dispense prescription medicine based on a prescription written by a doctor licensed in Japan. If you lose your medicine or need treatment during your stay, you will need to see a local doctor in person and get a Japanese prescription.

How to Visit a Clinic and Fill a Prescription as a Traveler

If you need medical care while traveling in Japan, the basic flow is simple once you know it.

Most everyday health problems are treated at neighborhood clinics, not large hospitals. For general illness, look for an internal medicine clinic, called naika in Japanese. Keep these steps in mind:

• Bring your passport and a way to pay. Many small clinics do not take every card or digital wallet, so carrying some yen in cash is practical.
• Prepare a list of your current medicines and health history. Write the generic names rather than brand names, because brand names often differ between countries.
• Without Japanese public health insurance, you pay the full cost of the visit and any tests yourself. Ask for an itemized receipt to send to your travel insurance company.
• Receive your paper prescription, called a shohosen. Most clinics in Japan do not hand out medicine directly. They give you a prescription to take to a separate pharmacy.
• Fill your prescription quickly. A Japanese prescription is usually valid for four days, counting the day it was issued — weekends and holidays included — unless the doctor writes a different period on it. If it expires, you will need a new clinic visit.
• Take it to a dispensing pharmacy, called a chozai yakkyoku. These pharmacies show a sign saying they accept prescriptions. My guide on pharmacy in Japan explains how to find one and what to expect at the counter.

For a serious emergency, such as sudden chest pain, trouble breathing, or an injury, call 119 for an ambulance.

Planning Your Care Before and After Your Trip

Before you travel, talk to your prescribing doctor at home. Make sure you have enough of your regular medicine for the whole trip, within Japan's personal import limits. Keep your medicine in its original packaging, with the pharmacy label showing your full name, the generic drug name, and the daily dose.

If you do need care in Japan, go in with realistic expectations. Doctors here will look after you, but their focus is your health during your stay. A doctor in Japan will assess your current symptoms and prescribe what you need until you leave, not extra months to take home.

After you return, book a follow-up with your regular doctor. Tell them about any medical visits in Japan, including the names and doses of any medicine you received. Your doctor can review how you are doing and continue your long-term treatment.

Planning a Trip With Ongoing Medication?

If you take regular medication and are planning a trip to Japan, the safest moment to check is before you pack. Japan Medication Entry Check is a written review by a licensed pharmacist in Tokyo: you send your list, and I explain how each medicine is treated at the Japanese border and what to prepare. Entry Check starts at US$100 for up to 5 items (medicines, supplements or devices); US$150 with an Application Map. US$30 per item beyond 5 (tax incl.).

This service is not a substitute for a doctor's diagnosis or treatment. It does not prescribe, and it does not influence how much medicine a doctor in Japan will prescribe. For anything about your treatment itself, your own doctor comes first.
