Why Italian medicines can be illegal in Japan
Japan is known for having one of the world's most restrictive pharmaceutical regulations. The problem is not the medicines themselves but their active ingredients: molecules considered harmless in Italy and sold freely in pharmacies or supermarkets can be classified as stimulants, psychoactive drugs or precursor substances in Japan.
The most common case involves pseudoephedrine, a decongestant present in many nasal sprays and cold medicines widely available in Italy. In Japan, pseudoephedrine is considered a raw material for producing stimulants and is subject to the Stimulant Control Law. Importing it — even in a minimal quantity for personal therapeutic use — can constitute a criminal offence.
Which medicines are at risk
The highest-risk categories are:
- Nasal sprays and decongestants containing pseudoephedrine (common in many Italian OTC products)
- Asthma inhalers with active ingredients that fall under Japanese controlled substances
- Stimulant or energy medicines with specific molecules
- Anxiolytics and sleeping pills, if possessed above permitted quantities
The critical point is that the trade name of the medicine is irrelevant: what matters is the active ingredient. A decongestant sold under one name in Italy may contain a molecule that is completely illegal in Japan.
Consequences for those arriving with unauthorised medicines
Penalties depend on the substance and quantity, but can be very serious:
- Seizure of the medicine at customs
- Deportation with immediate repatriation
- Arrest for illegal importation of controlled substances, with possible detention
These are not extreme or rare cases: there are documented incidents of tourists stopped for medicines they considered completely ordinary.
How to protect yourself: prior authorisation
The solution exists and is formal: before travelling to Japan you can apply for an official Yakkan Shoumei authorisation from the Japanese Ministry of Health. The application is submitted online, specifying the active ingredient, dosage and duration of the therapy.
With this document you can bring the medicine legally. Without it, even genuine ignorance of Japanese law is no defence.
Practical advice before you travel
Before closing your suitcase, do not just look at the trade name of your medicine. Check the active ingredient on the package leaflet and verify whether it is on the list of substances controlled under Japanese law, available on the Japanese Ministry of Health's official website or through the Japanese Consulate in Italy.
