Bringing Medicine to Japan: What Travelers Should Check Before Packing

Passport, prescription paper, medicine package, and packing checklist for travel to Japan Travel Medical Care
Check medicine quantity, active ingredients, and required documents before traveling to Japan.

If you are bringing medicine to Japan, do not check only whether it is legal in your home country. Japan has its own rules.

Quick answer: many travelers can bring a personal-use amount of ordinary medicine into Japan without applying for Import Confirmation, but the limits depend on the type of medicine. Some controlled medicines need permission in advance, and some substances cannot be brought into Japan even if they were prescribed overseas.

This article is for general information only. Rules can change, and individual medicines may be treated differently in Japan. Before travel, check the official Japanese government pages linked at the end of this article.

The 5 Checks Before You Pack

Before putting medicine in your suitcase, check these five points.

  1. Is it for your own personal use?
  2. Is it a prescription drug, OTC drug, external-use drug, injection, cosmetic, or medical device?
  3. How much are you bringing?
  4. Does it contain a controlled substance in Japan?
  5. Do you need Import Confirmation or another permission before departure?

If you are not sure about point 4, do not guess. Ask your prescribing doctor for the active ingredient name, then check with the relevant Japanese authority before travel.

Common Quantity Guide

According to Japan’s Ministry of Health, Labour and Welfare, some personal-use medicines may not require Import Confirmation if they are within certain amounts.

Common examples include:

  • Prescription drugs: up to 1 month supply
  • Injectable drugs and syringes for the drug: up to 1 month supply, limited to pre-filled syringes or self-injection kits
  • External-use drugs, excluding poison, deadly poison, and prescription drugs: up to 24 per item
  • Other drugs and quasi-drugs: up to 2 months supply
  • Cosmetics: up to 24 per item
  • Disposable contact lenses: up to 2 months supply

These are not a guarantee that every product can enter Japan. Prohibited or controlled drugs are handled separately.

Controlled Medicines Need Extra Care

Some medicines require permission before entering Japan. These may include medicines containing narcotics, stimulants’ raw materials, psychotropics, cannabis-related substances, opium-related substances, or other controlled substances.

Examples listed by Japan’s Narcotics Control Department include:

  • Morphine, fentanyl, oxycodone, and some codeine products
  • Lisdexamfetamine, known by brand names such as Vyvanse or Elvanse
  • Some psychotropics, depending on the drug and quantity

Some medicines cannot be imported by individual travelers even if they were prescribed in another country. The Narcotics Control Department gives Adderall as an example that cannot be brought into Japan because its active ingredient is amphetamine.

Do not rely on brand names alone. The official controlled-substance list may use active ingredient names, not the product names you know from home.

When Import Confirmation May Be Needed

Import Confirmation may be needed if you bring more than the personal-use amount, or if your medicine falls into a category that requires a procedure before travel.

If you need Import Confirmation, you should receive it before leaving your home country and show it to customs when entering Japan.

For controlled substances such as narcotics or stimulants’ raw materials, a separate permission process may apply. The Narcotics Control Department says travelers should apply at least 14 days before travel, and last-minute applications may not be accepted.

What to Carry With Your Medicine

To reduce confusion at the airport or pharmacy, carry:

  • Medicine in the original package when possible
  • A copy of your prescription
  • A doctor’s letter or medical certificate when needed
  • A list of active ingredient names, strengths, and doses
  • Any Import Confirmation or controlled-drug permission documents, if required

Keep important medicine in your carry-on bag unless airline or security rules require otherwise.

If You Are Unsure

If your medicine is important for daily treatment, check early. Do not wait until the week of departure.

Use this order:

  1. Ask your doctor or pharmacist for the active ingredient name.
  2. Check the official MHLW and Narcotics Control Department pages.
  3. Contact the relevant Japanese authority if the rule is unclear.
  4. Keep documents with the medicine during travel.

Quick Packing Checklist

Before leaving for Japan, ask:

  • Is this medicine for my own use?
  • Is the amount within the official personal-use guide?
  • Does it contain a controlled substance in Japan?
  • Do I need Import Confirmation or permission?
  • Do I have the prescription, doctor’s note, or certificate if needed?
  • Is the medicine in its original package or clearly identifiable?

If any answer is unclear, check before you pack.
