Bringing Prescription Medicine to Japan: Import Rules and Approval Steps
Bringing Prescription Medicine to Japan: Import Rules and Approval Steps
Last updated and official sources checked: September 26, 2026
Some general prescription medicine can be carried into Japan for personal use without an Import Confirmation when every condition in the Ministry of Health, Labour and Welfare (MHLW) rule is met. For ordinary prescription medicine, one condition is a quantity of no more than one month's supply.
That is not blanket permission. A prescription issued outside Japan does not override a prohibited-ingredient rule, controlled-substance procedure, product classification, quantity limit, or Customs requirement. If the exact active ingredient or category is unclear, do not pack it based on a brand name or blog answer; ask the responsible Japanese authority first.
This guide is general Japan-side planning information, not medical, pharmaceutical, legal, Customs, or travel advice. The current official source and the responsible authority control if they differ from this page. Export, transit, airline, security, storage, and treatment-continuity rules are separate checks.
Which Japan-Side Path Should You Check?
| Your situation | Likely Japan-side path | Authority | Do not assume |
|---|---|---|---|
| Ordinary prescription medicine for your own use, no more than one month's supply, and not prohibited or separately controlled | Check every condition in the ordinary personal-use rule; MHLW says an Import Confirmation is not required when they are all met | MHLW personal-use medicine guidance | One month makes every medicine permissible |
| Ordinary prescription medicine above one month's supply | Apply for an Import Confirmation before entering Japan | MHLW Import Confirmation Q&A and online-system overview | A prescription or doctor's note replaces the application |
| Narcotic or stimulants' raw material | Follow the advance-permission process for entering and, when applicable, leaving Japan | Narcotics Control Department (NCD) application guidance | An ordinary Import Confirmation replaces NCD permission |
| Psychotropic medicine | Check the exact ingredient, dosage form, and total amount against the live NCD table | NCD psychotropic guidance | Every psychotropic follows the same paperwork rule |
| Prohibited or uncertain ingredient or category | Stop and ask the appropriate MHLW regional bureau or NCD office before packing | MHLW or NCD, depending on the possible category | A foreign prescription, original packaging, or past travel proves permission |
| Injectable, syringe, injector, or personal medical device | Check the item-specific MHLW rule, then check NCD too if the medicine may be controlled | MHLW general guidance; NCD for controlled ingredients | A device alone and a medicine-plus-device kit are treated alike |
Important: "One month's supply" is one condition in MHLW's ordinary prescription path. It is not a universal allowance, a fixed tablet count, or automatically 30 days, and it does not displace controlled- or prohibited-substance rules.
Write Down the Exact Product and Travel Details First
Before searching a list or contacting an office, record:
- the generic or active ingredient, not only the brand name
- strength per tablet, dose, milliliter, patch, vial, or other unit
- prescribed dose and dosage form: tablet, liquid, patch, inhaler, vial, pre-filled syringe, injector, or device
- total quantity and supply duration under the prescribed directions
- whether the patient will carry it or it will be sent separately
- passenger name, arrival date, airport or port, and flight or cruise number
- departure date and whether any controlled medicine will leave Japan again
- a valid prescription or doctor note, plus clear product and packaging records where the procedure requests them
This inventory matters because Japan classifies active ingredients, not every foreign brand name. MHLW also asks for product, ingredient, amount, form, and arrival details when a pharmaceutical inspector answers a case. Do not send Omnishoku or another unofficial site your prescription, diagnosis, passport, or itinerary.
General Personal-Use Quantity Rules
MHLW's current traveler page lists these category-specific boundaries below which an Import Confirmation is not required:
| MHLW category | Current boundary in the general rule | Important boundary |
|---|---|---|
| Poison, deadly poison, or prescription drug | Up to one month's supply | Must still be for personal use and not prohibited or separately controlled |
| Eligible drug for external use | Up to 24 per item | Excludes poisons, deadly poisons, prescription drugs, and other dosage forms excluded from this category; confirm Japan's classification |
| Injectable drug with its syringe | Up to one month's supply | Only within the pre-filled-syringe or self-injection-kit framing |
| Other drugs and quasi-drugs | Up to two months' supply | Do not assume a product sold over the counter abroad is in this Japanese category |
| Household-use medical device | One set | Device type and personal-use classification still matter |
| Disposable contact lenses | Up to two months' supply | This is a device-category boundary, not a general medicine rule |
These amounts are Import Confirmation boundaries, not proof that an ingredient is allowed. Japan's legal category may differ from the label or sales category in another country. Cosmetics and supplements have their own classification issues and are outside this prescription-focused guide.
For injectables, note a wording difference: the MHLW traveler table says "up to one month," while the current English Q&A describes a qualifying medicine-and-syringe combination as less than one month's supply. If your quantity is near that boundary, ask the pharmaceutical inspector responsible for your arrival place instead of guessing.
When You Need Import Confirmation
MHLW's current English Q&A says more than one month's supply of general prescription medicine requires an Import Confirmation before entry. A syringe imported by itself also requires Import Confirmation as a medical device, even if it is only one piece; that is different from a qualifying medicine-and-syringe combination.
MHLW's public Application for Import Confirmation overview uses the terms Import Confirmation and Yunyu Kakunin-sho/Import Certificate. You may still see the older reader term "Yakkan Shoumei" online; use the live MHLW process rather than treating it as a separate permit or relying on an old form.
The current personal-use workflow is:
- Use MHLW's online system and choose the current personal-use application category.
- Attach a valid prescription or doctor note for every medicine or device in the application. MHLW currently asks for patient, medicine or device, and doctor information.
- Attach airline or cruise documentation showing the arrival date, arrival place, flight or cruise number, and applicant/passenger name.
- Monitor the registered contact and answer any return or correction instructions.
- Download the issued confirmation without altering it and keep it available to show Customs if requested.
The MHLW Q&A says a complete application is normally issued in a few business days, excluding Saturdays, Sundays, and national holidays. That is not a deadline or approval guarantee: incomplete or returned applications take longer. Apply with a practical buffer as soon as the required documents and stable travel details are available.
Use the system help desk only for operation or technical questions. Questions about the product, category, amount, application content, or limited time before departure go to the pharmaceutical inspector or regional bureau responsible for the arrival place. The live MHLW Import Confirmation hub keeps those roles and contacts together.
Controlled Medicines Use a Different Check
Do this check before relying on the ordinary one-month rule. The NCD separates narcotics, psychotropics, stimulants, stimulants' raw materials, cannabis, and opium, and the procedure varies by category. Its linked Controlled Substances List uses substance names rather than every brand name; the document linked on September 26, 2026 was dated December 12, 2024.
| NCD result | What the current guidance says |
|---|---|
| Narcotic or stimulants' raw material in a permitted personal-treatment path | Obtain advance permission to enter and leave Japan as applicable |
| Psychotropic at or below its substance-specific total amount, not in injection form | NCD says no doctor's certificate or permission under the Narcotics and Psychotropics Control Law is required; other import rules can still apply |
| Psychotropic above the table amount or in injection form | Carry the prescribing doctor's certificate described by NCD; contact MHLW as directed if the supply exceeds one month |
| Ingredient marked prohibited in the live NCD guidance or list | Do not bring it based on a foreign prescription; follow the category-specific NCD answer |
| Ingredient, salt, concentration, formulation, or category is uncertain | Ask NCD or the relevant MHLW office before packing |
For a narcotic or stimulants'-raw-material permission case, the live NCD application page currently calls for the applicable import form, an export form if leftover medicine will leave Japan, a prescribing doctor's medical certificate with the requested details, and product or package evidence. Submit the case to the NCD office responsible for the arrival airport.
NCD currently says to apply at least 14 days before travel and warns that last-minute handling is not assured. It also says the traveler must carry the controlled medicine personally rather than send it or entrust it to someone else, and must show the import/export certificate to Customs. An ordinary MHLW Import Confirmation cannot replace this permission or make a prohibited substance permissible.
Injectables, Syringes, and Personal Medical Devices
Do not collapse these into one rule:
- A qualifying injectable and its syringe may fit MHLW's pre-filled-syringe or self-injection-kit boundary.
- A syringe by itself requires Import Confirmation as a medical device under the current MHLW Q&A, even for one piece.
- A household-use medical device has a general one-set boundary, while disposable contact lenses have a separate two-month boundary.
- A controlled active ingredient still sends the medicine to the NCD check, regardless of the delivery device.
For an insulin product, injector, CPAP-related item, or another device, identify every component and ask MHLW about the exact combination if the published category does not clearly fit. This page cannot classify a product from a photo or brand name.
Carrying Is Not the Same as Sending
This guide covers medicine accompanied by the patient. MHLW's current Q&A says psychotropics, narcotics, and stimulants' raw materials may not be sent from overseas. NCD also says a traveler using its controlled-substance path must carry the medicine personally and may not entrust it to another person.
Do not plan to mail the remainder, use a commercial-order workaround, or have another adult carry it based on the quantity table. Ask the responsible authority about your actual carry/send facts before departure.
Travel-Day and Customs Checklist
- Keep any Import Confirmation or NCD import/export certificate accessible rather than in baggage you cannot reach.
- Keep the product, prescription or doctor documentation, and package evidence organized for the actual traveler.
- Follow Japan Customs' current passenger declaration instructions. Customs says all passengers must declare their belongings; travelers who cannot use the green channel, including those carrying restricted goods, use the red channel.
- Present the applicable confirmation or permission when directed. Do not alter a certificate.
- Do not treat airline security screening, original packaging, a duty-free allowance, or previous entry as Japan-side import approval.
Japan Customs' personal-import summary confirms the personal-use quantity framework, but MHLW and NCD control the more detailed health and controlled-substance procedures.
Longer Stays Need a Continuity Plan
If you cannot carry enough medicine under the ordinary path, address the import procedure before departure and separately ask a qualified clinician about continuity of care. Do not assume the same brand, formulation, dose, prescribing route, cost, or insurance coverage exists in Japan.
Use the broader moving-to-Japan guide for relocation planning and the first-month checklist for healthcare and arrival administration. Students can continue with the language-school student visa guide; eligible Canadians using that route can use the working holiday guide. A school, employer, or program can help with planning, but it does not authorize medicine import.
Frequently Asked Questions
Is a foreign prescription enough?
No. It can be required supporting evidence, but Japan's ingredient classification, quantity rule, Import Confirmation process, NCD rule, and Customs procedure still apply.
Does one month's supply always mean no paperwork?
No. That boundary belongs to the ordinary prescription rule and only works when all other conditions are met. A controlled ingredient, prohibited substance, injection, device, or uncertain category can follow a different path.
What if I only know the brand name?
Ask the prescriber or dispensing pharmacist for the exact active ingredient, strength, dosage form, dose, and total amount. Then use the live NCD list and MHLW guidance or contact the appropriate office. Do not infer the answer from a similar brand sold elsewhere.
What about ADHD or another controlled medicine?
There is no safe category-wide answer. The NCD's live FAQ illustrates that medicines used for the same condition can follow different rules because their active ingredients differ. Check the exact ingredient and formulation; do not generalize one example to every ADHD or controlled medicine.
Can I bring insulin, an injector, or a syringe?
The answer depends on the exact medicine, ingredient, combination, form, and quantity. MHLW distinguishes a qualifying pre-filled syringe or self-injection kit from a syringe imported alone. Check NCD as well if the ingredient may be controlled.
Can someone else carry or mail my medicine?
Do not assume so. NCD says medicine in its permission path must be personally carried and not entrusted to another person, while MHLW says specified controlled categories may not be sent from overseas. Ask about your exact product and method.
Who should I contact if I am unsure?
For ordinary medicines, devices, quantities, or Import Confirmation content, contact the MHLW regional bureau or pharmaceutical inspector responsible for the arrival place. For a possibly controlled ingredient, use the NCD guidance and airport-based office list. The online-system help desk is for system operation, not product classification.
