Over-the-Counter Medication
Which Non-Prescription Medicines Are Not Allowed?
Some non-prescription medicines that are easy to buy in the UK, US, or Europe aren’t allowed in Japan.
Products with certain stimulant or narcotic ingredients are a no-go, even if they’re legal at home.
Examples of banned products include:
- NyQuil
- Actifed
- Sudafed
- Advil Cold & Sinus
- Dristan Sinus
- Tylenol Cold
- Vicks Inhaler
- Lomotil
Japan’s rules change sometimes, so double-check with government sources before you fly.
Which Over-the-Counter Medicines Are Acceptable?
You’re allowed up to a 60-day supply of approved over-the-counter medicine and pills for personal use.
This also covers vitamins and contact lenses.
If you need more than 60 days’ worth:
- You’ll need to apply for a “Yunyu Kakunin-sho” (import certificate) before you arrive.
Tip: Always carry medicines in their original packaging and, if possible, keep an ingredients list handy.
Prescription Medication
Bringing Prescription Medicines: What Is Allowed?
You can bring prescription medicines into Japan if they’re for your own use, aren’t on Japan’s banned or controlled lists, and don’t go over a one-month supply.
Always check if your medication is allowed in Japan before you travel.
Contact your doctor if you’re unsure, and look up the latest controlled substances list from Japanese authorities.
- Only for personal use
- One-month supply max
- Must not be banned or tightly regulated
Medicines You Cannot Bring into Japan
Some prescription medicines are totally banned in Japan, no matter your reason.
Stimulants like amphetamines or drugs for ADHD (Adderall, Dexedrine) aren’t allowed.
Narcotics, such as heroin, opium, and some cannabis medicines, including painkillers, are prohibited.
There are no exceptions, even if you have a doctor’s note.
Outright Prohibited Examples
| Drug Type | Example Medicines |
|---|---|
| Stimulants | Adderall, Dexedrine |
| Narcotics | Heroin, opium, morphine (without approval) |
| Cannabis-based | Some CBD oil, medical cannabis |
- Carry your prescription with your medication
- Keep medicines in their original, clearly labelled pharmacy containers
- Don’t mix pills in unmarked bottles or combine different meds in one container
These steps help customs officials understand your situation and prevent confusion.
It’s smart to have your documents in English or Japanese.
Do You Need to Apply for a Yunyu Kakunin-sho?
Quick Guide: Medication Quantities Allowed into Japan
If you’re travelling to Japan with medicine or medical devices, you’ll want to know if you need a Yunyu Kakunin-sho (import certificate).
The Narcotics Control Department needs this under the Pharmaceutical Affairs Law and Customs Law.
Apply for a Yunyu Kakunin-sho if you are:
- Bringing more than a 1-month supply of prescription meds
- Carrying over a 2-month supply of non-prescription meds or vitamins
- Travelling with more than 24 pieces per item of over-the-counter treatments (for external use)
- Bringing more than one medical device, like inhalers or syringes
You need to get this certificate before you arrive and show it at customs if asked.
The process can take up to 3 weeks, so plan ahead.
- Overseas prescriptions aren’t valid in Japan. If you need more medicine than allowed, you’ll have to see a doctor in Japan.
- Talk to your healthcare provider at home if these limits might affect your treatment.
| Type of Item | Maximum Quantity (Without Certificate) |
|---|---|
| Prescription medicines | 1 month supply or less |
| Non-prescription medicines | 2 month supply or less |
| Vitamins | 2 month supply or less |
| Cosmetics/OTC treatments (external use) | 24 pieces or less per item |
| Medical devices (e.g. inhalers) | 1 per person |
Seriously, sort this out before you go to avoid a mess at customs.
