ADHD in Japan: The Complete Guide for Foreign Residents
ADHD can be diagnosed and treated in Japan, health insurance covers it, and English-speaking care exists. But Japan handles ADHD medication more strictly than almost any other developed country, and this catches foreign residents off guard in three ways: Adderall is flatly illegal here, a diagnosis from abroad must be re-confirmed by a doctor in Japan before stimulants can be prescribed, and the main stimulant, Concerta, runs through a national registration system that has been under supply pressure.
None of these are dead ends. They just mean ADHD is the one area of psychiatric care where you should understand the system before you move, not after.
Can you continue ADHD treatment from abroad?
Yes, but not by handing over your old prescription. Foreign prescriptions have no force in Japan, and a doctor here must confirm the ADHD diagnosis themselves before stimulants can be prescribed, so bring your records (diagnosis, test results, medication history with doses and response), book a psychiatrist who handles adult ADHD, and expect the first visits to revisit your history; with good records this is a confirmation, not a from-scratch diagnosis. Full walkthrough in our step-by-step diagnosis guide.
Which ADHD medications are legal in Japan?
| Medication | Status in Japan |
|---|---|
| Adderall, Dexedrine (amphetamines) | Illegal. No prescribing pathway, and cannot be brought into the country in any amount |
| Concerta (methylphenidate ER) | Approved for all ages, but only via registered doctors, pharmacies, and patients |
| Ritalin (methylphenidate IR) | Available, but approved only for narcolepsy, not ADHD |
| Vyvanse (lisdexamfetamine) | Approved only for ages 6-18; cannot be started in adults |
| Strattera (atomoxetine) | Approved for all ages, ordinary prescription, generics available |
| Intuniv (guanfacine ER) | Approved for all ages, ordinary prescription |
Two consequences follow:
- If you take Adderall, do not bring it to Japan under any circumstances; possession is a criminal matter with no exemption paperwork, so plan a medication change before the move.
- If you're an adult on Vyvanse, it can't be started in adults here; the usual path is Concerta or a non-stimulant.
Travel rules differ by drug (Vyvanse needs advance permission; Concerta can be carried within a quantity allowance); see our guide to bringing ADHD medication into Japan and the ministry's English import pages.
What is the registration system?
A triple registration: your doctor, your pharmacy, and you. Since late 2019, Concerta and Vyvanse have run through a national proper-distribution system built to prevent stimulant diversion, so choose a clinic that is actually registered and bring photo ID to your first prescription; it is a pharmaceutical control, not a government watchlist, and medical confidentiality applies as usual. How the system works, step by step, is in our medication guide.
The Concerta supply shortage
Concerta has been in short supply since late 2025, and continuing patients have been protected throughout; new starts may face a waiting list or an alternative first. The alternatives, generic atomoxetine and guanfacine, are real options that sit outside the stimulant registration system. We keep a regularly updated article on the supply situation.
How does getting diagnosed in Japan work?
The typical path at a clinic that handles adult ADHD: a detailed interview about your current difficulties and your childhood (ADHD is developmental, so evidence of symptoms before roughly age 12 matters; school records and a parent's memories genuinely help), standardized rating scales, and, when ADHD is suspected, usually cognitive testing such as the WAIS, which clarifies your profile but is not by itself an ADHD test. Most straightforward cases reach a conclusion over two to four insured visits. Details in the diagnosis guide and testing guide.
Treatment beyond stimulants
Japanese practice often starts adults on a non-stimulant: atomoxetine (Strattera) builds over several weeks and suits people who want steady all-day coverage, while guanfacine (Intuniv) can help notably with impulsivity and emotional reactivity. Alongside medication, structure-building approaches (coaching, CBT-informed skills work, workplace adjustments) pair well with insured medical care; side effects and the choice between the three medications are compared in our medication guide.
