Travelling to Japan with ADHD: Medications, Customs Rules and Healthcare
Japan has some of the world's strictest rules on ADHD medications. Know exactly what you can bring, what requires prior permission, and how to access care.
Japan and ADHD: what changes the moment you land
Japan enforces some of the strictest medication import laws in the world. Several ADHD medications that are prescribed routinely in other countries are completely prohibited here, and others require advance permission from Japanese authorities before you travel[1]. Getting this wrong at customs can result in confiscation, detention, and in serious cases, arrest[2].
This guide covers what you can and cannot bring into Japan, the advance permissions you may need, how to access psychiatric care as a foreign visitor, and how to communicate your diagnosis in an emergency. Carry your Nomedic International Patient Summary (IPS) throughout your trip: it gives any clinician your full medication list and diagnosis instantly, without language barriers.

Key risks
Key risks for ADHD travellers in Japan
Prohibited and restricted medications at the border
Amphetamine-based medications such as mixed amphetamine salts are completely banned under Japan's Stimulants Control Act and cannot be imported under any circumstances. Methylphenidate is classified as a psychotropic and requires advance documentation; lisdexamfetamine is classified as a Stimulants' Raw Material and requires advance permission from Japan's Narcotics Control Department before entry.[1]
Severe legal consequences for non-compliance
Carrying a prohibited substance into Japan, even with a valid foreign prescription, can result in arrest, detention of up to 23 days without charge, and deportation. Check your medication's classification with the Narcotics Control Department well before you travel.[1]
Very limited medication options in Japan
Only four ADHD medications are approved in Japan: methylphenidate (Concerta), atomoxetine (Strattera), guanfacine (Intuniv), and lisdexamfetamine (Vyvanse, children only). If your usual medication is not on this list, plan a medication review with your prescriber before departure.[4]
Difficulty obtaining a local prescription as a short-stay visitor
Japanese psychiatrists who are certified to prescribe methylphenidate must be registered with both the government and the medication manufacturer. New adult patients face significant barriers to obtaining a prescription. See the In Country tab for how to locate a certified psychiatrist before you travel.[5]
Sleep disruption, jet lag, and structured routine
Japan's time zone can sit many hours ahead of your origin, making medication timing and sleep schedules difficult to maintain. See the In Country tab for practical strategies on managing schedule disruption in Japan.
Preparation checklist
- Identify your medication's classification under Japanese law — Check the Narcotics Control Department website at ncd.mhlw.go.jp to confirm whether your active ingredient is prohibited, requires a Yunyu Kakunin-sho, or requires NCD advance permission.
- Apply for a Yunyu Kakunin-sho or NCD permit at least four weeks before departure — Applications are submitted online via the MHLW portal; processing typically takes two to three weeks, and longer around Japanese public holidays (Golden Week, Obon, New Year).
- Arrange a pre-travel medication review with your prescriber — If your current medication is prohibited in Japan, discuss switching to an approved alternative (methylphenidate, atomoxetine, or guanfacine) with enough lead time to stabilise before you travel.
- Obtain a signed specialist letter in English and Japanese — The letter must state your diagnosis, the INN and brand name of your medication, your prescribed dosage, and the medical necessity of carrying it.
- Create or update your Nomedic IPS — Your IPS stores your diagnosis, medication INN, dosage, allergies, and emergency contacts in a format readable by any clinician worldwide. Check my meds on the Nomedic app.
- Identify an English-speaking psychiatrist in your destination city before travel — Tokyo and Osaka have certified ADHD psychiatrists; book a provisional appointment in case you need a local prescription. Find a specialist via Nomedic's provider search.
- Confirm your travel insurance covers ADHD explicitly — Declare the condition, your medication, and any comorbidities at application. Learn more in the insurance section above.
- Pack all medication in original labelled packaging in your hand luggage — Do not place controlled or psychotropic medications in checked baggage.
- Carry printed copies of your import certificate, specialist letter, and prescription — Digital copies on your phone plus printed backup; customs officers may require physical documents.
- Save Japan's emergency numbers offline — Ambulance and fire: 119. Police: 110. Save these in Nomedic before you fly. View card in the Nomedic app.
Documents to carry
Documents to carry when travelling to Japan with ADHD
Japan's strict medication controls mean documentation is not optional. Carry physical and digital copies of everything listed below, stored in the Nomedic app for offline access.
Your International Patient Summary (IPS)
Your Nomedic IPS contains your ADHD diagnosis, current medications with INNs, dosages, known allergies, and emergency contact details in a standardised format any clinician can read. In Japan, where language barriers are a real obstacle, showing a clinician your IPS on arrival at a clinic or emergency department removes the need to explain your diagnosis verbally.
Your IPS also acts as supporting clinical evidence alongside your import certificate and specialist letter. Japanese customs officers and hospital triage staff can verify your medication is prescribed and necessary without requiring you to communicate in Japanese.

Medications advice
Bringing your ADHD medications to Japan
Japan regulates ADHD medications under the Stimulants Control Act and the Narcotics and Psychotropics Control Law, administered by the Ministry of Health, Labour and Welfare (MHLW). Amphetamine salts are completely prohibited and cannot be imported under any circumstances.[1] Methylphenidate is classified as a psychotropic: a personal supply of up to 30 days OR 2.16 g (whichever is lower) may be carried without a certificate, but exceeding either threshold requires a Yunyu Kakunin-sho (輸入確認書) import certificate issued before departure.[8][2] Lisdexamfetamine is classified as a Stimulants' Raw Material and requires advance permission from Japan's Narcotics Control Department, applied for at least two weeks before travel. Submit your application to the Regional Bureau of Health and Welfare covering your airport of arrival.
A note on naming: the import certificate is officially called the Yunyu Kakunin-sho (輸入確認書) — formerly known as the Yakkan Shoumei (薬監証明), which is still the term used in older travel guidance and at some embassies. They refer to the same document.[10]
Do not post your medication to Japan.
Importing psychotropic or controlled ADHD medications through postal mail is illegal in Japan, with no allowance for a 30-day personal supply by post. There have been cases of arrests made when medication was sent by post; always carry your medication in person in your hand luggage and declare it at customs.
ADHD medications: brand names, INNs, and Japan availability
Four ADHD medications are approved in Japan; the table below shows their INNs, local brand names, and any travel-relevant notes.[4]
Class I (第1種) psychotropic under Japan's Narcotics and Psychotropics Control Act. Personal supply over 30 days or 2.16 g requires a Yunyu Kakunin-sho. Dispensing is restricted to physicians, pharmacies and patients all registered in the ADHD適正流通管理システム (ADHD Proper Distribution Management System).
Approved in Japan for narcolepsy only, not for ADHD. Do not expect a Japanese psychiatrist to prescribe this for ADHD.
Not a controlled substance in Japan. No import certificate required. Available via psychiatrists and specialist clinics.
Not a controlled substance in Japan. Approved for ADHD. Access via psychiatrists; availability may vary by region.
Classified as a Stimulants' Raw Material under Japan's Stimulants Control Act. Requires NCD advance permission before import. Approved in Japan for children under 18 only; not prescribed to adults. Domestic Japanese prescriptions are limited to 30 days per dispensing under MHLW restrictions.
Completely prohibited under the Stimulants Control Act. Cannot be imported under any circumstances, even with a valid foreign prescription.
Atomoxetine and monoamine oxidase inhibitors (MAOIs)
Atomoxetine must not be taken within two weeks of an MAOI. If you have been prescribed an MAOI for any reason during your trip, inform the prescribing doctor that you take atomoxetine. Japan's psychiatric clinics typically screen for this interaction, but confirm it explicitly if you receive any new prescription while in Japan.
Travelling with psychotropic medications: import process steps
If your ADHD medication falls into the psychotropic or Stimulants' Raw Materials category, these steps apply regardless of which airport you arrive at in Japan.

At your destination
Healthcare and prescriptions in Japan
Japan operates a universal National Health Insurance (NHI) system, but foreign visitors on short stays are not enrolled and pay full cost at the point of care. There is no reciprocal healthcare agreement between Japan and other countries. Emergency treatment is available to all regardless of insurance status, but all costs must be settled directly or reclaimed through your travel insurer. A private psychiatric consultation at an English-speaking clinic in Tokyo costs approximately ¥14,500 to ¥19,000 per session without insurance; at a Japanese-language clinic under NHI, enrolled residents pay around ¥1,500 per visit, but short-stay tourists cannot access this rate.[6]
Foreign prescriptions are not accepted at Japanese pharmacies. If you run out of atomoxetine or guanfacine, a local psychiatrist can issue a Japanese prescription for these non-controlled medications. Methylphenidate can only be prescribed by a certified psychiatrist registered with both the Japanese government and the manufacturer; a new adult patient visiting for a short period will face significant barriers to obtaining this prescription.[5]
Controlled ADHD medications are dispensed through registered channels only
In Japan, methylphenidate (Concerta) can only be dispensed by pharmacies that are registered with the government and the manufacturer. Not all pharmacies stock it, and supply is often ordered per prescription. If you need an emergency supply, go directly to a hospital psychiatry department (精神科, seishinka) with your Nomedic IPS and specialist letter; they can refer you to a registered dispensing pharmacy.
Finding an ADHD specialist
ADHD is treated by psychiatrists (精神科医, seishinka-i) and psychosomatic medicine doctors (心療内科, shinryou-naika). Both work in hospital psychiatry departments and private clinics. In Tokyo, English-speaking ADHD clinicians are available at clinics such as Tokyo Mental Health and Roppongi Clinic; in Osaka and other major cities, English provision is limited and appointments may require a Japanese-speaking intermediary. Walk-in psychiatric appointments are uncommon; most clinics require a booking, and wait times for new patients at English-speaking clinics range from one to three weeks. Identify your nearest certified clinic before you travel and save the contact details offline.[7]
Search for providers near your destination
Use Nomedic's provider search to find ADHD specialists in Japan. Save the address and phone number offline before you travel.
If you run out of medication or your supply is confiscated
Running out of ADHD medication in Japan is stressful but manageable if you act quickly. Atomoxetine and guanfacine are the most accessible routes to an emergency supply, as neither requires controlled substance certification at the dispensing stage.
Managing schedule disruption and routine day to day in Japan
Japan can sit anywhere from 8 to 17 hours ahead of your origin timezone, creating significant disruption to medication timing, sleep, and structured routine. Japan's dense urban environments, high-stimulus settings such as busy train stations, and a demanding sightseeing culture can compound the challenge.
Discuss medication timing adjustment with your prescriber before you travel, and agree a plan for shifting your dose schedule gradually across the first two to three days. Japan's convenience stores (konbini such as 7-Eleven, Lawson, and FamilyMart) are open 24 hours and widely available, making it easy to buy food, water, and basic supplies at any hour if you need to stabilise your routine outside normal meal times. Japan's punctual train system provides predictable structure that can support a consistent daily schedule once you are settled. If you use any sleep aids, confirm their import status separately: some common sleep medications contain substances that are restricted in Japan.
Jet lag and missed doses are not the same as a clinical crisis
Disrupted sleep and missed or delayed doses in the first few days in Japan can feel destabilising, but they rarely represent a clinical emergency. Rest, rehydrate, and return to your normal dose schedule as soon as your body clock allows. If significant distress, agitation, or new psychiatric symptoms persist beyond 48 hours after stabilising your routine and medication timing, contact your travel insurer's assistance line and follow the guidance in the Emergency tab.
Japanese phrases for clinicians
Show your Nomedic IPS first — it removes the need to explain your diagnosis verbally. If verbal communication is needed:
“私はADHD（注意欠如・多動症）があります。”
I have ADHD (Attention Deficit Hyperactivity Disorder).
“私は今、症状が悪化しています。”
I am currently experiencing worsening symptoms.
“精神科の医師に診ていただけますか？”
Can I see a psychiatrist?
“私はADHDのためにこの薬を飲んでいます。”
I take this medication for ADHD.
“一番近くの精神科はどこですか？”
Where is the nearest psychiatry department?
“この薬の緊急補充が必要です。”
I need an emergency supply of this medication.
Insurance considerations
What to know about travel insurance
Many travel insurance policies treat ADHD as a pre-existing condition and exclude any related claim unless you have declared it and paid for specialist cover. Private psychiatric care in Japan for a foreign visitor without insurance can cost between ¥10,000 and ¥50,000 per consultation, and emergency hospital admission adds considerably to that figure.
What to look for in a policy
Not just 'pre-existing conditions covered'. Your condition should be named on the schedule of cover.
Covers repatriation to your home country if local care is insufficient or your medication cannot be sourced in Japan.
Covers emergency replacement if your medication is lost, confiscated at customs, or delayed.
So someone can communicate with Japanese clinicians on your behalf. English-speaking psychiatrists are concentrated in Tokyo and Osaka.
What to declare at application
Declare thoroughly. Incomplete disclosure can invalidate your entire policy, not just the ADHD-related claim.
Specify whether your diagnosis is inattentive, hyperactive-impulsive, or combined presentation, and note any formal severity rating.
Use the INN (International Nonproprietary Name) alongside the brand name. Declare whether your medication requires a controlled substance import permit for Japan.
Include any recent hospitalisations, medication changes, or psychiatric crisis contacts.
Declare comorbidities such as anxiety disorder, depression, autism spectrum disorder, or sleep disorder, as these are common with ADHD and are often assessed separately by underwriters.
Your policy number and emergency assistance line, saved alongside your IPS and accessible offline.
Japan has no reciprocal healthcare agreement with EU or EEA countries, so EHIC and GHIC cards provide no entitlement to subsidised care in Japan. All treatment costs are payable in full at the point of service. Travel insurance with ADHD cover declared is essential regardless of any card you hold.
Emergency protocol
Going to a hospital emergency department in Japan
A psychiatric crisis in Japan requires going to the emergency department (救急外来, kyuukyuu-gairai) of a general hospital with a psychiatry department. Contact your travel insurer's assistance line before attending if your condition allows; they can locate an English-speaking facility and may be able to arrange direct billing. If you are in immediate distress, call 119 for an ambulance.
When you arrive — follow in order
Full clinical picture in seconds, no verbal explanation needed.
Hand your phone to the triage nurse:
私はADHDがあり、精神科の緊急診察が必要です。
I have ADHD and need urgent psychiatric assessment.
If your medication was confiscated or if you need an emergency prescription, these documents are essential for the treating clinician.
Include any medications you have temporarily missed or delayed due to travel, as this is clinically relevant for the treating psychiatrist.
Calls and location
Ambulance and fire in Japan: call 119. Police: call 110. If you do not speak Japanese, the Emergency Call Translation Service (available through some ambulance dispatchers in major cities) may be available; state 'English' when the call connects. Your hotel concierge can also assist with emergency calls.
In hospital
Methylphenidate and atomoxetine interact with several medications used in emergency and surgical settings, including antihypertensives and MAOIs. Tell any treating clinician your full medication list immediately, using your Nomedic IPS.
After any emergency
Before you leave the hospital if possible.
Required for insurer reimbursement and continuity of care on your return.

Frequently asked questions
Can I bring my ADHD medication into Japan?
It depends entirely on the active ingredient. Amphetamine salts (Adderall, Dexedrine) are completely prohibited and cannot be imported under any circumstances. Methylphenidate is a psychotropic and can be imported in limited quantities, but above the MHLW threshold quantity requires a Yunyu Kakunin-sho import certificate obtained before travel. Lisdexamfetamine requires advance permission from the Narcotics Control Department. Atomoxetine and guanfacine are not controlled substances in Japan and can generally be carried without a certificate for a personal supply.
Never post medication to Japan
Mailing psychotropic or controlled ADHD medication to Japan is illegal. Carry it in person in your hand luggage and declare it at customs with your import certificate.
Are ADHD medications available in Japanese pharmacies?
Atomoxetine (Strattera) and guanfacine (Intuniv) are available at pharmacies with a Japanese prescription. Methylphenidate (Concerta) is only dispensed by government-registered pharmacies on prescription from a certified psychiatrist, and supply is often ordered per individual prescription rather than held in stock. As a short-stay visitor, obtaining a methylphenidate prescription as a new adult patient is very difficult. Bring a sufficient supply of your medication from home.
What are the emergency numbers in Japan?
Ambulance and fire
119
Police
110
General enquiries (non-emergency)
#7119 (Tokyo and some major cities) — connects to a nurse triage line
How can I communicate my ADHD diagnosis in an emergency in Japan?
Show your Nomedic IPS first. If verbal communication is needed:
“私はADHD（注意欠如・多動症）があります。”
I have ADHD (Attention Deficit Hyperactivity Disorder).
“私はADHDのためにこの薬を飲んでいます。”
I take this medication for ADHD.
How does Japan's timezone and structured environment affect my medication schedule?
Japan can sit 8 to 17 hours ahead of your origin timezone, which can disrupt both medication timing and sleep. Discuss a dose-shift plan with your prescriber before departure. Japan's highly structured daily routine, including punctual public transport and consistent business hours, can actually support re-establishing a stable schedule once you adjust.
Use Japan's konbini network
Convenience stores (7-Eleven, Lawson, FamilyMart) are open 24 hours nationwide. They provide consistent access to food, water, and basic supplies regardless of the time of day, which helps maintain a routine during the adjustment period.
Do I need special travel insurance to visit Japan with ADHD?
Yes. Japan has no reciprocal healthcare agreement with other countries, so all medical costs are payable in full at the point of care. A private psychiatric consultation in Tokyo costs approximately ¥14,500 to ¥19,000 per session. Standard travel insurance policies may exclude ADHD as a pre-existing condition; you need a policy that explicitly covers ADHD, declares your current medication, and includes emergency medical evacuation.
Declare thoroughly
Subtype, current medication and dose, last episode, associated conditions such as anxiety or sleep disorder. Incomplete disclosure invalidates the entire policy, not just any ADHD-related claim.
