Taking Adderall to Japan: what you must know before you travel

Adderall is completely prohibited in Japan. Amphetamine, its active pharmaceutical ingredient, is classified as a banned stimulant under Japan's Stimulants Control Act, and no import pathway exists for any traveller, under any circumstances.^[1]

Japanese customs officials do not make exceptions for foreign prescriptions, and possession at the border can result in detention and criminal prosecution under the Stimulants Control Act. This guide explains how to plan your trip safely, what alternatives are available in Japan, and what to do if you need support while you are there.^[2]

Medical disclaimer: This guide is for informational purposes only and does not constitute medical advice. Always consult your prescribing doctor before travelling with medication, particularly regarding supply quantities, storage requirements, and import documentation. Regulations change; verify all rules with Japan's Ministry of Health, Labour and Welfare (MHLW) before departure.

Before you travel

Documentation for travelling to Japan when you take Adderall

Because Adderall cannot enter Japan under any circumstances, the most important document you need before travel is not an import certificate but a comprehensive medical summary to show a Japanese psychiatrist. Japan's Narcotics Control Department (NCD) is explicit: amphetamine is prohibited even as a prescribed medicine from another country. Your preparation should focus on transitioning to a permitted alternative before you depart, or arranging access to one in Japan.^[1]

What your medical summary letter must include

Your full legal name. Your current diagnosis (the condition name only, not a description). The INN (international nonproprietary name) and brand name of Adderall. Your dose and frequency. The duration of your current treatment. Your prescribing doctor's full name, registration number, clinic letterhead, and signature. A Japanese translation is strongly recommended to facilitate assessment by a local psychiatrist. Notarisation is not required by law but may assist with translation credibility.

Have your letter translated into Japanese by a certified translator before departure. An official translation makes it significantly easier for a Japanese psychiatrist to understand your treatment history quickly, which matters if you need to discuss switching to a locally available medication.

Planning your medication before you travel to Japan

The only safe plan for travelling to Japan when you take Adderall is to discuss a temporary medication switch with your prescribing doctor well in advance of your departure date. As of 2024, locally available alternatives in Japan include methylphenidate (Concerta), atomoxetine (Strattera), lisdexamfetamine (Vyvanse, children under 18 only), and guanfacine (Intuniv) — all of which require a Japanese psychiatrist to prescribe them.^[3]

Allow at least two to three months before your trip to trial any new medication and confirm it is effective and tolerable for you. Switching medication and adjusting to a new country simultaneously is a significant stress; starting the switch early gives you time to identify any problems before you leave.

Do not rely on obtaining a prescription in Japan as your primary plan

Getting a new ADHD prescription in Japan as a short-term visitor is difficult. Diagnosis typically requires two or more psychiatrist appointments. Concerta and Vyvanse are tightly controlled, require certified prescribers, and may not be available immediately. Plan your medication management before you fly, not after you land.

Packing and storing any permitted medication for travel to Japan

If you have transitioned to a permitted alternative such as methylphenidate (Concerta) before departure, store it according to the prescribing label and keep it in its original, pharmacy-labelled packaging at all times. The FDA label for amphetamine-based medications requires storage at 20–25°C (68–77°F), with short excursions permitted between 15–30°C (59–86°F); methylphenidate has a similar room-temperature requirement.^[6]

Split your supply between hand luggage and checked baggage. If one bag is delayed or lost, you retain access to at least part of your medication. For any permitted controlled substance, carry the import certificate (Yunyu Kakunin-sho) in your hand luggage alongside your doctor's letter, as customs officers may request it at the point of entry.

Questions to ask your prescriber before you travel

Bring this list to your appointment so your prescriber can write the right backup pathway for Japan.

If Adderall isn't stocked in Japan, can you write a backup prescription naming a sibling brand or the generic (Amphetamine)?
What wording on the doctor's letter will Japan's customs officials recognise? Should it list Amphetamine (INN), Adderall, dose, and total milligrams?
What's the safest plan if I run out of Adderall mid-trip — can you arrange an emergency refill remotely, or do I need a local consultation?
How should I time my doses around the time-zone change to Japan?
Is there a brand-specific reason I shouldn't switch to a local equivalent if the supply situation in Japan forces it?

At the airport and border

Airport security when travelling to Japan

At airports in your departure country, carry any permitted medication in its original labelled packaging and keep it accessible in hand luggage. Airport security staff at most international airports are familiar with prescription medications and rarely stop travellers carrying clearly labelled tablets. The issue arises at Japanese customs on arrival, not at departure security.

Do not attempt to carry Adderall through any airport with the intention of entering Japan. Even if the medication passes through departure security undetected, it will be subject to Japanese customs control on arrival. Japanese customs officers conduct secondary inspections and check active ingredients against the MHLW controlled substances database.

Customs and medication import rules for Japan

Japan's Narcotics Control Department states unambiguously that amphetamine, the active pharmaceutical ingredient of Adderall, is controlled as a stimulant under the Stimulants Control Act and cannot be imported into Japan even for personal medical use. There is no import certificate, no advance permission scheme, and no humanitarian exemption that changes this. The prohibition is absolute.^[1]

For travellers carrying a permitted controlled substance such as methylphenidate (Concerta), a one-month supply (up to 2,160 mg total methylphenidate) may be brought into Japan without an import certificate, provided it is accompanied by a doctor's letter^[1]; quantities exceeding this require a Yunyu Kakunin-sho applied for at least 14 days before travel through the Regional Bureau of Health and Welfare for your airport of arrival.

Adderall is a prohibited substance in Japan — there are no exceptions

Amphetamine is listed as a prohibited stimulant under Japan's Stimulants Control Act. Bringing Adderall into Japan, even in a sealed original pharmacy container with a valid prescription, constitutes a criminal offence. Article 41-2(1) of the Stimulants Control Act prescribes imprisonment of up to ten years for illegal possession. Japanese customs officials do not grant on-the-spot exceptions, and a foreign prescription carries no legal weight. Do not attempt to bring Adderall into Japan under any circumstances.

While in country

Adderall availability in Japan

Legal ADHD-medication alternatives in Japan

Brand	Legal status	Local availability
Adderall (amphetamine)	Banned — Stimulants Control Act	No import pathway
Concerta (methylphenidate ER)	Psychotropic — permit required >2.16 g	Adult ADHD via certified psychiatrists
Ritalin (methylphenidate IR)	Psychotropic — narcolepsy only	Not licensed for ADHD in Japan
Strattera (atomoxetine)	Non-controlled, prescription only	Available via psychiatrist

Adderall is not available in Japan in any form and cannot be obtained from any pharmacy or clinic. The active ingredient amphetamine is banned, not merely regulated, under Japanese law. No Japanese prescription can be written for it at any dose or for any purpose.^[4]

The following alternatives are approved and available in Japan with a psychiatrist's prescription: methylphenidate (Concerta/コンサータ), atomoxetine (Strattera/ストラテラ), lisdexamfetamine (Vyvanse/ビバンセ, currently restricted to patients under 18), and guanfacine (Intuniv/インチュニブ). Concerta costs approximately ¥3,000 (~$20 / ~€18) or more per month under Japan's National Health Insurance; without insurance, costs will be higher.^[5]

Be aware that even permitted stimulant medications such as Concerta are tightly controlled. Pharmacies dispensing them must be registered with the government, and stock may be limited — meaning you may not be able to collect the medication on the same day as your prescription.

Finding a psychiatrist in Japan

Only psychiatrists (seishinkai, 精神科医) can diagnose and prescribe for ADHD in Japan — general practitioners cannot. Look for a seishinka kurinikku (psychiatric clinic, 精神科クリニック). In Tokyo, Osaka, and Nagoya you will find clinics that can consult in English. Initial appointments under Japan's National Health Insurance (NHI) typically cost ¥3,000–¥5,000 (~$20–$34 / ~€18–€31), while private appointments range from ¥10,000–¥28,000 (~$67–$188 / ~€62–€173) depending on the clinic.^[5]

Diagnosis typically requires two or more visits, and the prescribing doctor must hold additional certification from the medication's manufacturer before they can prescribe stimulants such as Concerta. TELL Japan (telljp.com) is a non-profit that offers English-speaking mental health support and can assist with referrals.

Telemedicine services operating under Japanese law cannot prescribe controlled substances to short-term visitors. For medication access, an in-person psychiatric appointment is required.

Storing permitted medication while in Japan

If you are carrying a permitted alternative such as methylphenidate, the FDA label specifies storage at room temperature 20–25°C (68–77°F), with short-term excursions permitted to 15–30°C (59–86°F) Japan's summers can see temperatures exceeding 35°C in cities such as Tokyo, Osaka, and Kyoto, so avoid leaving medication in a car, in direct sunlight, or in a hot hotel room without air conditioning.^[6]

Store medication in a locked bag or hotel room safe. Keep it in its original, pharmacy-labelled container at all times. If your accommodation lacks reliable air conditioning during a heatwave, ask hotel staff whether a secure refrigerated storage option is available, and check your medication's specific label for cold storage tolerance before doing so.

Emergencies

What to do if something goes wrong with your medication in Japan

If you have transitioned to a permitted alternative before travel and that medication is lost or stolen in Japan, report the loss to the nearest police station (koban, 交番) and obtain a crime reference number. Contact your travel insurer immediately, as lost prescription medication may be covered under your policy.

If your permitted medication runs out unexpectedly, you will need to attend a psychiatric clinic in Japan to obtain a new prescription. Bring your medical records, your translated doctor's letter, and the original packaging or pharmacy label if available. Prescriptions for controlled substances in Japan are valid for only four days from the issue date, so fill the prescription at a registered pharmacy promptly.^[5]

If you arrived in Japan without having switched from Adderall and are experiencing difficulties, your only legal option is to attend a psychiatrist and discuss a locally available alternative. Attempting to have Adderall sent to you from abroad is also illegal under Japanese law.

Frequently asked questions

Can I bring Adderall into Japan?

No. Adderall's active ingredient, amphetamine, is classified as a prohibited stimulant under Japan's Stimulants Control Act, and no import is permitted under any circumstances — not even with a valid prescription. Attempting to bring Adderall into Japan can result in detention, prosecution, and imprisonment of up to ten years under Article 41-2(1) of the Stimulants Control Act.^[1]

Is there an import certificate or permit that allows Adderall into Japan?

No. The Yunyu Kakunin-sho (import certificate) system applies only to narcotics and psychotropic medications that are restricted but importable with permission, such as methylphenidate (Concerta). Amphetamine-based medications including Adderall fall into the prohibited stimulant category, for which no permission scheme exists. There is no application process and no exception.

Is Adderall available from pharmacies or doctors in Japan?

Adderall is not available in Japan in any form and cannot be prescribed or dispensed by any clinic or pharmacy. Locally available alternatives include methylphenidate (Concerta/コンサータ), atomoxetine (Strattera/ストラテラ), and guanfacine (Intuniv/インチュニブ), all of which require a prescription from a certified Japanese psychiatrist.

What should I do before travelling to Japan if I take Adderall?

Speak to your prescribing doctor at least two to three months before departure about switching to a medication that is legally permitted in Japan, such as methylphenidate or atomoxetine. Prepare a comprehensive medical summary letter — translated into Japanese — that documents your diagnosis, prior medications, dose, and treatment history. Store your full medical record on Nomedic so it is accessible to any clinician you see while abroad.

What if I run out of my permitted alternative medication in Japan?

Attend a psychiatric clinic (精神科クリニック) with your medical records and doctor's letter. A certified psychiatrist can assess whether to prescribe a locally available equivalent. Prescriptions for controlled substances in Japan are valid for four days only, so fill any new prescription at a registered pharmacy the same day. TELL Japan (03-5774-0992) can help locate an English-speaking clinic.

Can I have Adderall sent to me by post while I am in Japan?

No. Sending prohibited stimulant medications to Japan by international mail is also illegal under Japanese customs law. Parcels containing controlled substances are inspected, and any shipment found to contain amphetamine will be seized. Do not attempt to have Adderall sent from another country while you are in Japan.
