Japan - Medications, medicine and drugs in Japan

This page last updated: November 2017

Taking Prescription or Controlled substances into Japan might ruin any travel if not researched properly, so here is a complete overview on the subject.

This was taken straight from r/JapanTravel's FAQ because I am the one who researched, wrote and maintained it until mid 2017, at which point this page is the most current:

The quick answer version

  1. Check the main chemical/ingredient the desired drug have (scientific name, common name. Example: Advil is actually Ibuprofen)

  2. Check if that chemical is the kind of drug on the Prohibited list, taking note of the Exceptions list. If it is, you cannot take it to Japan, otherwise, see the next item:

  3. Check if that chemical is in the Controlled list. If it is in either (controlled or exceptions) lists, see the next item (otherwise it's ok):

  4. Check if you will be carrying more than the maximum allowed quantity. If it is, see the next item (if carrying less, it's ok):

  5. You will need to declare it with a form called "Yakkan Shoumei" prior to your travel


The in-depth answer

There are three categories of drug/quasi drug permits: Free (no need to declare), Controlled (you need to declare them - the form is called "Yakkan Shoumei form"), and Prohibited (absolutely no way to import, jail term possible).

We will cover them in reverse order, which means prohibited first. If, by the end of these lists, your prescription drug is not mentioned, you are pretty much on the clear, but remember these change often, so when in doubt, no site on the internet can be 100% correct, you should call the Japan Consulate-Embassy in your country (or mail them) with the list of medicines you need and inquire about them. Some of the sources here are from 2015 and might have been tweaked, and despite being on the official pages, might be outdated.

This guide is based on the Ministry of Health, Labour and Welfare official site, which will link to a good FAQ about importing controlled drugs and the same details listed bellow (except we organized and alphabetized them), another link for the official form and list is (this, which links to this PDF version, which is based on The Narcotics Control Department site


Strictly Prohibited

All forms of Narcotics and Psychotropics unless those controlled and declared (see Controlled drugs bellow), as such as, in any form or amount:

  • Heroin, Opium powder, Methamphetamine, Amphetamine, Dexamphetamine, Artificially-produced halucinogens;
  • Cannabis;
  • Stimulants raw materials such as ephedrine, pseudo-ephedrine, and any of their pharmaceutical (raw) forms, see below for low doses allowances.
  • Pharmaceutical form (raw) Codeine (3-Methylmorphine), Morphine, Oxycodone, Pethidine or Hydrocodone, or any other narcotic.

Pharmaceuticals containing (non-raw), in low doses, are allowed:

  • No more than 10% ephedrine, methyl-ephedrine, phenylacetic acid;
  • No more than 50% norephedrine (phenylpropanolamine);
  • Prescription forms of narcotics are allowed if declared with a Yakkan Shoumei form (see below).


Controlled drugs

The following drugs can be imported as long you carry the same or lower amount listed. If you are carrying more than mentioned in the list, you must have a certificate (Rx/Prescription) written by your doctor identifying the disease, treatment and necessity of the drugs, which each drug amount necessary. The doctor notice must contain the full doctor name and doctor registration number so authorities can check its authenticity if necessary, and a "Yakkan Shoumei" form, which must be submit by air-mail to the airport where you will be arriving at least two weeks prior your arrival. Read this official FAQ for how to handle the form and other documentations
