Packing for a ski trip to Japan usually means thinking about warm layers, waterproof clothing, ski gear and everything you'll need for long days in the snow. But there's one part of your packing that deserves a little more attention: medication. Japan has strict regulations around bringing medicines into the country, and some medications that are completely routine and legally prescribed elsewhere are treated very differently under Japanese law. That doesn't mean you need to travel without your medication. It simply means you should check the rules before you fly, rather than discovering them when you arrive.
Some Everyday Medicines Can Be Restricted in Japan
One of the most surprising things for visitors is that restrictions can apply to medicines that seem completely ordinary.
Cold and flu remedies are a good example. Products containing pseudoephedrine or ephedrine can be subject to Japan's stimulant-control regulations depending on their concentration. This means that a cold medicine you might normally pick up at a pharmacy without giving it a second thought could require a closer look before you put it in your suitcase.
The same applies to certain prescription medications.
Adderall, for example, contains amphetamine, which is controlled in Japan. The Japanese Ministry of Health, Labour and Welfare states that Adderall cannot be imported into Japan, even when it has been prescribed for ADHD treatment.
Vyvanse is a different case. Its active ingredient, lisdexamfetamine, is controlled as a stimulant raw material in Japan, but it can be brought into the country with advance permission.
This is why checking the specific medication and its active ingredients is so important. Two medications prescribed for the same condition can have completely different requirements.
Prescription Medication: Don't Assume Your Prescription Is Enough
For many prescription medicines, bringing a personal supply into Japan is possible without special procedures, provided the medication is not prohibited or specially controlled and the quantity is within the permitted limit.
Japan's current guidance generally allows up to one month's supply of prescription medicine for personal use without an Import Confirmation. If you need to bring more than that, you may need to apply for an Import Confirmation before travelling.
But there are important exceptions.
Narcotics, stimulants and certain psychotropic medications are subject to additional rules. Some require advance permission, while others cannot be brought into Japan at all.
So if you take medication regularly, don't simply look at the number of tablets you're carrying. Check the medication itself and whether its active ingredient is controlled in Japan.
What About Painkillers and Cold Medicine?
It's easy to think of a ski trip as a reason to pack a few extra painkillers, cold remedies or other pharmacy essentials.
But this is exactly where it's worth being cautious.
Japan regulates certain ingredients found in common medicines, including pseudoephedrine, ephedrine and codeine, among others. The rules can depend on the formulation and concentration, so the brand name alone isn't always enough to tell you whether something is permitted.
If you're unsure about a medicine, check its active ingredients against the official Japanese guidance before you travel.
And don't assume that because something is available over the counter at home, it is automatically unrestricted in Japan.
What About ADHD Medication?
This deserves particular attention because the rules can be surprising.
As mentioned above, Adderall cannot be brought into Japan, while Vyvanse may be permitted with advance permission. These are both medications used to treat ADHD, but they are regulated differently because of their active ingredients.
If you take ADHD medication, check the Japanese requirements well before your trip. You may need to arrange permission before departure, and you should never wait until you arrive in Japan to find out.
Keep Your Medication in Its Original Packaging
Once you've established that your medication is permitted, make things as straightforward as possible.
Keep it in its original packaging, with the prescription label clearly visible. If appropriate, carry documentation from your doctor that explains what the medication is and why you take it.
Japan's Ministry of Health, Labour and Welfare recommends having documentation that can explain the medication you're carrying and the condition for which it is being used.
It's also a good idea to carry your medication with you rather than putting essential medication into checked luggage.
Do You Need an Import Confirmation?
For some medications, yes.
An Import Confirmation is a document issued by the Japanese authorities that allows travellers to bring certain medicines into Japan for personal use.
If you need one, it must be obtained before you leave home.
The application can be made online for applicable personal-import procedures, but the requirements depend on the medication you're bringing.
This is particularly important if you're carrying more than the standard personal-use quantity or if your medication falls into one of the controlled categories.
What If You Need Medication During Your Ski Trip?
It's tempting to think you'll simply buy whatever you need once you arrive.
Japan has excellent pharmacies and healthcare services, but you shouldn't assume that your usual medication will be available in the same form or under the same name. More importantly, the fact that something is readily available where you live doesn't mean that the same active ingredient is unrestricted in Japan.
For medication that you rely on, it's much better to plan ahead.
And when it comes to the aches and pains that can come with several days of skiing, medication isn't always the only answer.
After a big day on the mountain, your body may simply need some recovery time, stretching or professional treatment. If you're feeling sore after skiing or dealing with a niggle that isn't going away, take a look at a physio session with Nomad Wellness.
What Else Should You Pack for Japan?
Medication is only one part of preparing for a ski trip.
Once you've checked what you're allowed to bring, you can concentrate on everything else you'll need for the mountains, from ski clothing and layers to footwear and the little essentials that are easy to forget.

The Most Important Thing to Remember
Japan's medication rules can be stricter and more complicated than you might expect.
A medicine that is perfectly legal where you live may be restricted in Japan. Adderall, for example, cannot be imported, while Vyvanse requires advance permission. Some cold and flu medicines containing ingredients such as pseudoephedrine or ephedrine can also be subject to restrictions.
The best thing you can do is check before you travel.
Look at the active ingredients in your medication, check the current Japanese government guidance, and allow enough time to apply for any required permission.
A few minutes of preparation before your trip can save you a lot of stress when you land.
Then you can get on with the important part of your trip: enjoying Japan's incredible snow.
Always Check the Official Guidance
Medication regulations can change, and the rules depend on the specific medicine, ingredients and quantity.
Before travelling, check the latest guidance from Japan's Ministry of Health, Labour and Welfare and, where necessary, contact the relevant Japanese authority about your specific medication.
