Request a Free Human Review

Send us the medicine name, quantity and arrival date. Our Japan-based team will personally review the likely requirements and normally reply within one business day.

Enter the brand name if you do not know the active ingredient.

✓ No payment or document upload is required at this stage.

Planning ahead matters: advance NCD permits take at least 2 weeks to process, and a Yunyu Kakunin-sho should be applied for well before departure. Don't leave it until the week you fly.

How the free human review works

A database result is only a first screening. Whether your medicine can enter Japan depends on its active ingredient, strength, form, quantity and your length of stay. Here is what happens after you submit.

Step 1

Tell us about your medication

Send the medicine name, dosage, quantity and travel date using the form above. No payment or medical documents are needed at this stage.

Step 2

We review the likely requirements

Our team checks the active ingredient against current MHLW and NCD classifications and identifies whether a Yunyu Kakunin-sho, permit or translation may be needed.

Step 3

Receive your next steps

Normally within one business day you receive a plain-English explanation of the likely requirements. If paperwork or translation is needed, we quote the fee before any work begins.

For more than one month's supply, confirm the separate Import Confirmation (Yunyu Kakunin-sho) requirements with the MHLW pharmaceutical-import authority. Must be hand-carried, cannot be mailed.
Cannabis, Marijuana & High-THC Products Marijuana, THC edibles, THC vapes, THC oils Prohibited Do not travel with cannabis, marijuana or high-THC products.Cannabis plant material and products containing Δ9-THC above Japan's applicable residual limits are prohibited under the revised Cannabis Control Act (in force since Dec 2024) and can lead to arrest, regardless of legality in your home country. Trace residual Δ9-THC at or below the relevant product-specific limit may fall outside narcotics controls, but CBD and other cannabinoid products require product-specific verification before travel (see the CBD row).
CBD Products CBD oil, CBD gummies, CBD isolate Specialist check Product-specific verification is required.CBD products are assessed under Japan's current component-based rules: the product form, cannabinoid composition, laboratory documentation and applicable residual THC limits must be checked against current official guidance before travel. Do not rely on a "THC-free" marketing label alone.
Anxiety & Sleep (Benzodiazepines & Hypnotics) Xanax, Valium, Ativan, Klonopin, Ambien Restricted Requirements depend on the active ingredient and total quantity.Classified as psychotropics. Non-injectable psychotropics at or below the substance-specific quantity in the official NCD table generally do not require an NCD permit or doctor's certificate.

For more than one month's supply, confirm whether an Import Confirmation (Yunyu Kakunin-sho) is also required.

Note: Tramadol is not classed as a narcotic.
Herbal Medicines (Chinese/Kampo) Ephedra (ma huang), some herbal blends Check ingredients Check the active ingredients before travel.Most Kampo is fine. The issue is controlled actives: ephedra contains ephedrine, a Stimulants' Raw Material. Blends with ephedrine or pseudoephedrine over 10% are controlled.

Plain antihistamines (Claritin, Zyrtec, Allegra/fexofenadine, loratadine) are fine. The "-D" decongestant versions are the problem. Phenylephrine (Sudafed PE) is not restricted.
OTC Antihistamines & Sleep Aids Benadryl, ZzzQuil, Unisom, Dramamine Allowed Generally allowed for personal use within limits.Plain diphenhydramine (Benadryl), doxylamine and dimenhydrinate are not controlled substances in Japan and are generally allowed up to a 2-month supply for OTC medicines. The risk sits with combination "-D" products containing pseudoephedrine, not the plain antihistamine. Check the label of multi-symptom versions.
Cough Syrups (with Codeine) Codeine-based syrups Permit required Check the concentration and formulation.Preparations containing more than 1% codeine or its salt are controlled as narcotics and require advance NCD permission.

Please read first: Use this table as a screening guide, not as a border decision. The entries above are general indications based on official guidance available at the time, not a determination for your specific case. Whether a medicine may be brought into Japan depends on its active ingredient, strength, form, quantity and current official classification, so the status and quantities shown may apply rather than being fixed legal thresholds. Always verify against the official sources before travel.

Important Notes

  • The certificate referred to here is the Yunyu Kakunin-sho (輸入確認書), the import confirmation previously known as the Yakkan Shoumei.
  • Always check the active ingredient, not just the brand name. Many OTC cold and allergy products that are legal elsewhere contain controlled stimulant ingredients.
  • If you're unsure whether your medication is restricted, check with Japan's Ministry of Health or let MedicTranslate prepare the required translations and guide you through the application process.
  • Always carry medicines in original packaging with your doctor's letter translated into Japanese. See our airport customs and documents guide for what to prepare and present at the border.
  • For a more detailed check than this category table, use our free 5-minute medication self-assessment tool, available in 13 languages, no account required.
  • Dated source statement: This guide reflects the official information available as of the Last Updated date shown above (11 July 2026). Requirements may change after that date, so please recheck the official sources before you travel.

Frequently asked questions

Is the human review really free?

Yes. The human review of your medicine's likely status and requirements is free and carries no obligation. If your situation needs translation, a Yunyu Kakunin-sho or permit-application support, we quote the fee before any work begins.

Can I check my medication myself right now?

Yes, two ways. The Instant Medication Guide above shows the general status of your medication category, and our free 5-minute self-assessment tool gives a more detailed check of your specific medicines, in 13 languages with no account required. The free human review is there when you want our team to personally confirm your situation and quote any paperwork.

Do I need a Yunyu Kakunin-sho?

It depends on the medicine's classification, quantity and dosage form. Prescription medicines exceeding one month's supply generally require an Import Confirmation. Prefilled syringes or self-injection kits of up to one month's supply may be exempt. Psychotropics also have substance-specific NCD quantity thresholds, so the active ingredient and total amount must be checked. Our check tells you whether your specific medicine and quantity are likely to need it.

How early should I apply?

We recommend applying for an Import Confirmation (Yunyu Kakunin-sho) 2 to 4 weeks before departure. Applications for advance NCD permission for narcotics and stimulants' raw materials should be submitted at least 14 days before travel and started as early as possible.

What information do you need from me?

Initially only the medicine name, dosage, quantity, your travel date and a way to contact you. If paperwork is needed, we will then request your prescription or doctor's letter.

Can you translate my prescription or doctor's letter?

Yes. Medical document translation between English and Japanese is MedicTranslate's core service, including prescriptions, doctor's letters and supporting documents for import confirmation applications.

What happens if my medication is restricted or prohibited?

If it is restricted, we explain the certificate or permit path and can prepare the paperwork. If it is prohibited, we explain why, and can help you discuss alternatives with a doctor in Japan through our healthcare coordination service.

Can you guarantee approval?

No. Final determinations are made only by Japanese authorities. What we do is help ensure the available documents are complete, consistently translated and submitted through the appropriate channel.

How is my medical information handled?

Your information is used to assess your enquiry and provide the requested service. It may be processed by authorised service providers supporting our systems, communications or application work, subject to our Privacy Policy, contractual safeguards and applicable data-protection requirements.

Don't wait until your departure date to confirm your medication requirements

Permits and certificates take weeks, not days. Send us your medicine details now and our team will personally review them and normally reply with your likely requirements within one business day, free of charge.
