Japan - Medications, medicine and drugs in Japan

This page last updated: March 2019

NEW RULES 2018: Psychotropics over the quantity specified by the NCO list, but for use under one month and not in injection form no longer require a form (Yakkan Shoumei), only a prescription identifying the disease, necessity for treatment, name of substances and quantities. Also, some new substances were added to the controlled substance list  
DECEMBER UPDATE: The MHLW and NCO changed the pages and form links. We updated them to the new links

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

The source of this information is straight from 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 site this, which also links to this PDF version of the list, also based on The Narcotics Control Department site (japanese)

In short, this page is updated with information from the Ministry of Health, Labour and Welfare, as well specifically the official Narcotics Control Department.


First things first: Any medication not listed or not of a forbidden type is allowed, only worry and check further if the medication is listed

Check calculator further down the page for a simpler approach, but still read the checklist to understand it.

  1. Check the main chemical/ingredient the desired drug have (scientific name, common name. Example: Advil is actually Ibuprofen, Xanax is Alprazolan and so on);

  2. Check if that chemical is the kind of drug on the Strictly Prohibited list. If it is on this list, you cannot take it to Japan;

  3. Check if that chemical is in the Controlled drugs list. If it is on this list, you need to check the quantity and time, otherwise it is allowed to take into Japan;

  4. If you are carrying less than the specified on the list, for less than a month, and none in injection form. You are allowed to take into Japan.

  5. If taking even more than the specified on the list, but still less than a month and none in injection form, you need a prescription from your doctor with why you need it, and how much; 

  6. If taking more than one month supply, or any of them in injection form, you will need to declare it with a form called "Yakkan Shoumeiprior to your travel (Example of filled form). In this case and this case only, you will check "Yes" in your Disembarkation card for item 3 "Controlled substances" upon arrival, which will cause the officials to check your Yakkan Shoumei.

To put it another way:

  • NOT ALLOWED: Anything on the Strictly Prohibited list, unless it is a Narcotic which you have a prescription for medical use (then you need a Yakkan Shoumei);
  • REQUIRES A Yakkan Shoumei FORM: Narcotics for medical use with legal prescription, or any Controlled drugs in excess of one month supply or in injection form, even if under the maximum allowed. In this case, you will also require to check "yes" in your Disembarkation Card (see below) on the item 3. "Possession of controlled substances..." and present the Yakkan Shoumei when requested. 
  • REQUIRES A prescription from your Doctor: Any Controlled drugs in excess of the amounts defined by the list, but for less than a month and not in injection form. You can check "No" for item 3 of the Disembarkation Card in this case.
  • ALLOWED: Substances not on the Prohibited list nor at the Controlled lists (if it is not on this document, it is allowed), or substances in the Controlled drugs but less than the maximum allowed, for less than a month and not in injection form. Again, check "No" for item 3 of the Disembarkation Card.

IMPORTANT: The Yakkan Shoumei form needs to be sent at least 2 weeks before your arrival.

Substance Check Calculator

Choose one of the controlled substances, how much you are carrying and how long you will stay to check what to do. If your medicine is not on the list, check if it doesn't contain one of them, and also check if they are one of the different forms of Amphetamines, Ephedrine, Narcotics or Opiates.

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

During Disembarkation, you will need to fill a quick form (see right). You only need to check "Yes" on item 3 "Possession of controlled substances" if you required a Yakkan Shoumei. Check "No" if you didn't need (based on the guide above) a Yakkan Shoumei. Checking "Yes" and not having a Yakkan Shoumei, and having more drugs than allowed or in injection form, might cause your entry to be denied. Checking "No" and being caught with more than allowed or in injection form, and not having the Yakkan Shoumei, will cause immediate arrest.

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 2018 and might have been tweaked, and despite being on the official pages, might be outdated.
