Planning a trip to Japan involves plenty of exciting decisions—where to stay, what to eat and everything you want to see while you are here. But if you or someone in your family takes prescription medication, there is another important item to add to your pre-travel checklist: checking whether you can legally bring that medication into Japan.
At Tokyo Family Stays, we sometimes receive questions from guests about travelling to Japan with prescription medication, particularly when families are coming for longer stays.
Japan closely regulates the importation of medicines and controlled substances. Bringing in a restricted medication without following the correct procedure can result in confiscation, significant delays at the border and potentially serious legal consequences.
The good news is that many common medicines can be brought into Japan for personal use. However, a medicine that is routinely prescribed or sold over the counter in your home country may be restricted—or classified differently—in Japan.
Our most important advice is simple:
Always check the active ingredient and confirm the current requirements with the relevant Japanese authorities before travelling.
Japan’s Ministry of Health, Labour and Welfare and its Narcotics Control Department provide the official rules. Your nearest Japanese embassy or consulate may also be able to direct you to the appropriate authority.
Rules can change, so this article should be treated as a general guide rather than medical or legal advice.
In many cases, yes.
According to Japan’s Ministry of Health, Labour and Welfare (MHLW), travellers can generally bring up to one month’s supply of an ordinary prescription medicine into Japan for their own use without applying for an Import Confirmation.
However, important exceptions apply.
Japan has separate restrictions covering narcotics, psychotropics, stimulants, stimulant raw materials and other controlled substances. Some medicines require advance permission regardless of the amount, while certain substances cannot be imported at all.
Never rely solely on whether a medicine is legal or available on prescription in your home country. Always check the active ingredient—not just the brand name—as well as the dosage form and total quantity you intend to carry.
If you are bringing more than one month’s supply of an ordinary prescription medicine, you will generally need to obtain an Import Confirmation—known in Japanese as a Yunyu Kakunin-sho (輸入確認証)—before entering Japan.
Japan’s online Application for Import Confirmation system began operating in February 2023. Since 1 July 2025, online applications have become the standard procedure for relevant personal-use Import Confirmation applications.
Through the system, applicants can create an account, complete an application, attach supporting documents and receive the approved Import Confirmation electronically.
The MHLW says a complete application will normally be processed within a few business days, excluding weekends and Japanese national holidays. Nevertheless, we recommend starting the process well in advance. Allowing up to three weeks gives you time to respond if officials request corrections or additional information.
Remember that an Import Confirmation is different from the permission required for certain controlled substances. If your medicine is a narcotic or stimulant raw material, follow the procedure specified by Japan’s Narcotics Control Department.
For a standard Import Confirmation application involving medicine carried into Japan, the MHLW currently requires:
A valid prescription or doctor’s letter identifying the patient, the medicine and the prescribing doctor
A document issued by the airline or cruise company showing the passenger’s name, arrival date, arrival point and flight or cruise number
Depending on the medicine and the applicable rules, additional documentation may be requested.
From a practical travel perspective, it is sensible to carry documents that clearly establish what the medicine is, why you need it and that it was legitimately prescribed for your personal use. These may include:
Your prescription or a copy of it
A doctor’s letter describing the medicine, dosage and medical need
Your itinerary or flight confirmation
Details or photographs of the medication and its packaging
Your approved Import Confirmation or controlled-substance permit, if required
A pharmacy receipt or invoice as optional supporting evidence
Keep the medicine in its original, clearly labelled packaging. Carry printed copies of important documents with you, preferably in your hand luggage, and keep electronic backups available on your phone or secure cloud storage.
Different ADHD medicines fall into very different legal categories in Japan.
Concerta contains methylphenidate, which Japan classifies as a psychotropic. Under the controlled-substance rules, travellers carrying no more than the listed threshold—currently 2.16 g of methylphenidate in total, excluding injectable forms—generally do not need a doctor’s certificate for the psychotropic itself. Above that threshold, a qualifying medical certificate must accompany the medicine.
The separate Import Confirmation rules still apply. For example, carrying more than one month’s supply may require an Import Confirmation even when the psychotropic quantity is below the controlled-substance threshold.
Other ADHD medicines are treated differently:
Vyvanse and other medicines containing lisdexamfetamine: Lisdexamfetamine is classified as a stimulant raw material. Advance permission is required before entering and, where applicable, leaving Japan.
Adderall and other medicines containing amphetamine: Amphetamine is classified as a prohibited stimulant. Japan’s Narcotics Control Department states that Adderall cannot be imported, even for medical treatment and even with a prescription.
This is why searching only for “Can I bring ADHD medication to Japan?” is not enough. You must check the precise medicine, active ingredient, dosage form and total quantity you plan to carry.
The same principle applies to medicines used for pain management, anxiety, sleep disorders and other conditions involving potentially controlled substances.
The general one-month allowance does not mean that every prescription medicine is permitted as long as you bring fewer than 30 days’ worth.
Narcotics such as morphine and fentanyl, and stimulant raw materials such as lisdexamfetamine, require advance permission from the relevant Japanese Regional Bureau of Health and Welfare. Some substances, including amphetamine and methamphetamine, cannot be imported by an individual traveller even for treatment.
Psychotropic medicines have their own documentation thresholds. Injectable psychotropics and quantities above the government’s listed limits require an appropriate medical certificate. An Import Confirmation may also be required for more than one month’s supply.
If you plan to leave Japan with a controlled medicine, check the export requirements as well. Separate import and export applications may be necessary.

Medication is not the only item that may be regulated.
The MHLW states that travellers can generally bring up to one month’s supply of a qualifying injectable medicine together with its pre-filled syringe or self-injection kit without an Import Confirmation.
However, bringing a syringe by itself—even a single syringe without the accompanying medicine—requires an Import Confirmation as a medical device.
Different rules may apply to controlled injectable medicines, so check both the medicine and the equipment before travelling.
For most ordinary over-the-counter medicines and quasi-drugs, travellers can generally bring up to a two-month supply into Japan for personal use without an Import Confirmation.
It can be useful to bring familiar basics from home, such as your preferred pain relief, cold medicine or allergy medicine. Japanese brands may contain different ingredients or dosages, and their packaging may be difficult to understand if you do not read Japanese.
However, never assume that an over-the-counter product that is legal at home is automatically legal in Japan.
Certain cold and sinus medicines contain pseudoephedrine, which Japan may regulate as a stimulant raw material depending on the product’s formulation and concentration. This includes some—but not all—products sold under the Sudafed brand.
Always check the complete active-ingredient list and formulation rather than relying on a brand name.
Before flying to Japan with medication:
Write down the brand name and every active ingredient.
Confirm the dosage form and exactly how much you will carry.
Check the current MHLW guidance.
Check the Narcotics Control Department guidance if the medicine could be controlled.
Contact the relevant Japanese authority if anything remains unclear.
Apply well in advance for any required Import Confirmation or controlled-substance permission.
Obtain a prescription or doctor’s letter and your confirmed travel details.
Keep the medication in its original, clearly labelled packaging.
Carry important documents in your hand luggage.
Keep secure electronic copies as a backup.
Check whether export permission will also be needed when you leave Japan.
Check every over-the-counter product by active ingredient before packing it.
Most travellers carrying ordinary prescription medication into Japan should not encounter problems when they understand the requirements and prepare in advance.
The important thing is not to assume that Japan’s rules are the same as those in your home country.
Start early, check the active ingredients, read the latest Japanese government guidance and contact the appropriate authority if you are uncertain. If you require an Import Confirmation, Japan’s online application system has made the process considerably more convenient.
