Disclaimer (YMYL): This article is general import and travel information, not legal, medical, or customs advice. Medication decisions belong with your doctor. Japanese import rules change and individual cases vary — confirm with MHLW or the relevant Regional Bureau of Health and Welfare before you travel. This page does not cover commercial or wholesale imports. Do not stop, start, or change prescribed medication based on this article.
Quick answer (30 seconds): If you bring medication into Japan for your own use, you can usually carry up to one month's supply of prescription drugs (or two months for most other drugs and quasi-drugs) without paperwork, per MHLW guidance. Need more? Apply for Import Confirmation — historically called Yakkan Shoumei (薬監証明), now issued online as Yunyu Kakunin-sho (輸入確認書) via MHLW's Application for Import Confirmationbefore you leave home, receive the certificate, and show it to customs if asked. Narcotics, stimulant raw materials, and prohibited drugs follow separate — often stricter — rules. Never sell or give imported medicine to anyone else.
What is Yakkan Shoumei — and what is Import Confirmation?
Yakkan Shoumei (薬監証明) is the familiar Japanese name for a personal-import certificate issued by Japan's Ministry of Health, Labour and Welfare (MHLW). The current official English term on MHLW systems is Import Confirmation, also written as (輸入確認書).

Yunyu Kakunin-sho
The certificate confirms that the medicines (or cosmetics / medical devices) you plan to bring match what MHLW has reviewed for personal use. It is not a prescription and not a substitute for medical advice — it is an import compliance document for customs and pharmaceutical inspectors.
MHLW states that when you bring medicines for personal use into Japan above the duty-free quantity limits, you must apply for Import Confirmation, receive it before you leave home, and show it to the customs officer on request when you arrive.

When you do NOT need Import Confirmation (quantity limits)
If every item in your luggage stays at or below the limits below, MHLW says you do not need to apply for Import Confirmation. These limits apply to personal use only — you may not sell or give the products to others.
Category
Maximum without Import Confirmation
Poison, deadly poison, prescription drugs
Up to 1 month's supply
Injectable drugs and syringes for the drug
Up to 1 month's supply — only pre-filled syringes or self-injection kits
Drugs for external use (excluding poison, deadly poison, prescription drugs)
Up to 24 units per item
Other drugs and quasi-drugs
Up to 2 months' supply
Cosmetics
Up to 24 units per item (any brand/color counts as one item type, e.g. lipsticks)
Household medical devices (e.g. electric massager)
Practical reading for residents and long-stay visitors: a one-month prescription buffer is fine for a short trip, but if you are moving to Japan or returning from home leave with a multi-month stockpile, you will likely exceed the prescription limit and need Import Confirmation — even if the medicine is legally prescribed abroad.
Designated-ingredient products: MHLW additionally restricts imports of foreign products containing certain designated pharmaceutical ingredients (see MHLW's linked table on the page above: table URL and ingredient list may be updated) that are marketed abroad for cognitive or mental-performance effects. An exception applies when use follows a doctor's prescription or instruction. Self-medication quantities brought by hand may be permissible during your stay — check the current MHLW table before packing.
When you MUST apply before traveling
Apply for Import Confirmation before departure if any of the following apply:
Any category above its limit — e.g. more than one month's supply of a prescription drug.
You need injectable medication beyond the allowed pre-filled / self-injection forms.
You are shipping medication to Japan by post or courier instead of carrying it (separate documentation rules apply; see below).
You carry medical devices or cosmetics above the per-item limits.
MHLW's Q&A stresses that the certificate is valid only when your actual luggage matches what the certificate lists. Do not alter the certificate — corrections invalidate it.
Choose "Import for personal use", complete the form, and upload required files per the portal manuals.
3. Wait for review
The relevant Regional Bureau of Health and Welfare reviews your application. Allow adequate lead time before your departure date — MHLW does not guarantee same-day turnaround.
4. Download the certificate
If approved, download the Yunyu Kakunin-sho / Import Confirmation from the status page. A PDF is also emailed to your registered address.
5. Travel with matching medicines
Carry the certificate (digital or printed per customs guidance) together with the medicines listed on it.
Online application is available for these purposes: personal use, import for treatment by doctors, and import for treatment/research. Other commercial purposes still require mail application.
Per MHLW's Q&A (online and mail procedures may request equivalent evidence):
Prescription or doctor's note for every medicine or medical device in the application, showing patient name, medicine name, and doctor's name. The importer name and patient name must match on the prescription.
Proof of travel showing arrival date, arrival place (airport/port), flight or cruise number, and passenger/applicant name — e.g. airline itinerary or ticket copy.
Product information as required by the application form (ingredient names, quantities, dosage forms).
For mail/courier imports, MHLW's Q&A additionally lists an invoice, air waybill, and customs postcard where applicable. Narcotics, psychotropics, and stimulant raw materials cannot be sent from overseas to Japan.

At customs: what to expect
Keep medicines in original packaging with labels intact when possible.
Carry your prescription or doctor's note even when within quantity limits — it helps if an officer questions a product.
If you hold an Import Confirmation, show it when customs requests it. You are not always inspected, but carrying mismatched quantities or unlabeled pills is a common delay trigger.
Medication imported for personal use must not be sold or transferred to other people.
Customs enforcement details and inspection frequency are not published as fixed rules — treat over-limit quantities without a certificate as high risk of confiscation.
Narcotics and Stimulants' Raw Materials — separate permission
Standard Import Confirmation is not enough for narcotics (e.g. morphine, fentanyl) or Stimulants' Raw Materials (e.g. lisdexamfetamine).
MHLW rules:
Importing narcotics and stimulant raw materials is strictly controlled.
For prescribed narcotics or stimulant raw materials for a specific patient, you must obtain permission from the Japanese Government (directors of the Regional Bureaus of Health and Welfare) before entering Japan.
Prohibited or controlled narcotics and stimulant raw materials cannot be brought in.
Narcotics / psychotropics / stimulant raw materials by mail
Cannot be shipped from overseas
If a medicine is legal in your home country but controlled in Japan, assume you need explicit MHLW guidance — do not rely on foreign packaging alone. ADHD and pain medications are frequent edge cases — check ingredient schedules on MHLW/NCD pages before packing.
Carrying medicine on your person and importing by international courier follow the same underlying MHLW framework, but courier shipments require the air waybill / bill of lading number in the application and may involve customs notification postcards. Apply through the same online portal unless MHLW directs you to mail procedures.
Do not ask family to mail controlled substances, injectables, or large prescription volumes without completing Import Confirmation first — customs may destroy the shipment and you may face legal consequences.
Import rules cover bringing stock from abroad. Once you live in Japan, ongoing treatment usually shifts to a Japanese clinic or hospital, where prescriptions follow domestic pharmacy rules and National Health Insurance pricing if you are enrolled.
Plan the handoff before your imported supply runs out — especially for chronic conditions, psychiatric medication, and controlled ingredients where a Japanese prescriber may need time to review your history.
Foreigner-specific friction points
"Legal at home" ≠ legal to import: US/EU/UK prescriptions do not override MHLW quantity limits or Japan's controlled-drug schedules.
Moving vs visiting: New residents often pack 3–6 months of prescription stock and unknowingly exceed the one-month limit — apply for Import Confirmation before the move, not at Narita.
Brand-name vs generic abroad: If your home-country product name differs from what MHLW expects, include active ingredient names on the doctor's note and application.
CBD / hemp-derived products: Often controlled or restricted in Japan regardless of legality elsewhere — treat as high-risk and contact MHLW before packing.
Language at customs: Officers may ask about ingredients in Japanese; carry an English prescription and ingredient list.
Re-entry trips: If you leave Japan and return with more medication, the same personal-import rules apply each time — there is no "resident exemption" from quantity limits.
FAQ
1. Is Yakkan Shoumei the same as Import Confirmation?
Yes. Yakkan Shoumei is the traditional name; MHLW's current online system issues Yunyu Kakunin-sho / Import Confirmation with the same compliance purpose.
2. Can I bring two months of prescription pills if I have a doctor's note?
Not without Import Confirmation. MHLW sets one month's supply as the limit for prescription drugs without a certificate — a foreign prescription alone does not raise the allowance.
3. Can I bring ADHD medication into Japan?
Some ADHD medicines contain stimulant-class ingredients controlled as Stimulants' Raw Materials in Japan. Standard personal-import limits may not apply; you may need special government permission or the medicine may be prohibited. Contact MHLW's Narcotics Control Departmentbefore traveling — do not assume a US/EU prescription is sufficient.
4. Do tourists and residents follow the same rules?
Yes. MHLW's personal-import framework applies to anyone entering Japan with medication for personal use, regardless of visa type.
5. What happens if I arrive without a certificate but over the limit?
MHLW requires prior approval for above-limit quantities. Over-limit medicines may be confiscated at customs, and you may face enforcement action. Apply early via the online portal.
6. Can I give unused medicine to a friend in Japan?
No. Personal-import medication must not be sold or given to others, even if it was legally imported for your own use.
7. Does travel insurance replace Import Confirmation?
No. Travel insurance covers medical costs; it does not exempt you from MHLW import rules. See japan-travel-insurance-guide for coverage — a separate topic from customs compliance.
