Guide to Bringing Medicines Into Japan

Nothing ruins a trip more than getting sick and not being able to treat your illness. Often, travelers will carry typical over-the-counter or prescription medicines with them to avoid any unpleasant situations. However, Japan’s strict rules concerning the importation of medicines may affect your packing list.

Find out what the rules are for bringing medicine to Japan, and what you might be able to get locally, with our step-by-step guide.

Over-the-Counter Medication

What OTC medications are prohibited?

While numerous medications are easily available in Western countries without a prescription, Japan takes a much harder line on certain ingredients.

The following are prohibited as they contain narcotic or stimulant ingredients in excess of the Japanese standard:

• These medications include (but are not limited to) Tylenol Cold, NyQuil, Actifed, Sudafed, Advil Cold & Sinus, Dristan Sinus, Vicks Inhaler, and Lomotil

Both the limits and what is considered a permitted ingredient is subject to change, so we advise consulting the Ministry of Health, Labour and Welfare’s English language website before any planned travel to Japan.

What OTC medication can you bring?

Travelers are permitted to bring a two-month (60 day) supply of any permissible over-the-counter medication, and an equivalent amount of vitamins. This also applies to contact lenses.

If you need more than two months’ supply, a Yunyu Kakunin-sho (輸入確認書) would then be needed.

Prescription Medication

Can I bring any prescription medicine into Japan with me?

In general, visitors to Japan are permitted to enter the country with prescription medicine without any special procedures if they adhere to the following conditions:

1. It is only for your personal use

2. It is not a prohibited or controlled drug in Japan

3. The quantity is up to 1 month’s supply.

Please review Japan's Controlled Substances List from the Narcotics Control Department to ensure that you follow the appropriate protocols for your medication.

Which prescription medicines are outright prohibited?

Opium, cannabis and stimulant drugs (Amphetamines, methamphetamines), including certain medicines for the treatment of ADD/ADHD (such as Adderall and Dexedrine) are strictly prohibited and illegal to bring into Japan.

Travelers face prosecution if in possession of them, even if those medications come with a foreign prescription or a customs declaration form – there are no exceptions.

On a related note, it goes without saying that hard drugs—like heroin, cocaine and MDMA—are similarly outright prohibited.

Does your prescription involve narcotics?

If your prescription medication involves the use of narcotics (e.g. morphine, codeine, oxycodone, pethidine, hydrocodone), you must seek advance permission from one of Japan’s eight Regional Bureaus of Health and Welfare.

You will need to submit an import application form as well as supporting documentation at least 14 days before traveling to Japan.

Does your prescription involve psychotropics?

The permitted dosage depends on the drug. For example, drugs such as Valium do not require a Yunyu Kakunin-sho if in quantities lower than 1.2 grams (the limit for the active ingredient, diazepam).

For an outline of which drugs fall into this category and the permitted dosages of each, please refer to this list provided by Japan’s Narcotics Control Department.

How to prepare permitted medicine to bring with you?

A copy of the prescription and a doctor’s note of explanation should accompany the medication when brought with you to Japan.

Medication should be stored in the original bottle – do not store in an unmarked container or bottle labeled for a separate medication.

Do I need to apply for a Yunyu Kakunin-sho?

Generally, you will need to apply for a Yunyu Kakunin-sho (special certificate of import), under the following circumstances:

1. You need greater than 1 month’s supply of prescription medicine

2. You need greater than 2 month’s supply of non-prescription medicine

3. You need syringes or a number of Medical Devices that exceed the limit.

In these cases a Yunyu Kakunin-sho must be issued in advance so that it can be presented at customs if required.

For information on how to obtain a Yunyu Kakunin-sho, visit the website for the Ministry of Health, Labour and Welfare (which includes up-to-date information on when you do and don’t need to rely on this form). Note that this process could take up to 3 weeks to obtain, which you should have before you leave home to travel to Japan.

Be aware overseas prescriptions are not honored in Japan – if your prescription needs are greater than what you are able to bring with you (even with a Yunyu Kakunin-sho), you will need to see a local care provider. In this case, it is wise to speak to your home country health care provider in advance if this may affect an ongoing treatment.

Summary: How much medicine can I bring into Japan?

The following provides a basic framework summarising what can be brought into Japan without requiring special permission (see Yunyu Kakunin-sho above). Note that the aforementioned rules and exceptions, based on prohibited ingredients, still apply.

Locally Available Medicine

Where can I get OTC medication in Japan?

Japan does have well-stocked pharmacies in most major metropolitan areas, so finding relief for minor health issues (like coughs and sore throats) is often easily accomplished.

Brands and medication ingredients may differ from what travelers may be used, but pharmacists can often assist in finding an effective alternative.

Common drug stores in Japan

	Welcia Drug store chain centered around the Kanto and Kansai regions.
	Matsumoto Kiyoshi Nationwide chain but dominant in Kanto region.
	Tsuruha Drug Nationwide drugstore chain.
	Daikoku Drug Nationwide drug chain, and concentrated around Kansai/Osaka.
	Sun Drug Nationwide drug chain.

Where can I get prescription medication in Japan?

For those in need of a specific prescription, a list of English-speaking doctors can be found through various embassy websites.

• British Embassy Tokyo: Sources of Medical Information in Japan
• US Embassy: Medical Assistance
• Australian Embassy Tokyo: Medical Information

Often, a phone call to an English-speaking doctor before a trip to Japan to discuss any medicines with questionable content will go a long way to avoiding any potential issues at customs.
