Can You Bring ADHD Medication to Japan? Adderall, Vyvanse, Concerta and the Law
The short answers: Adderall cannot be brought into Japan at all, under any paperwork, in any amount. Vyvanse can be brought in for personal use, but only with permission obtained before you travel. Concerta travels with you under Japan's psychotropic rules, no advance permit needed within the personal-use allowance. Atomoxetine and guanfacine are ordinary prescription drugs here, so a month's supply crosses with no procedure at all.
People get into serious legal trouble at Japanese airports every year over ADHD medication, almost always because they assumed a valid US prescription would count for something. It doesn't.
Which legal category is your medication in?
Stimulants (覚醒剤): absolutely prohibited
Amphetamine and its salts, meaning Adderall, Mydayis, Dexedrine, and Evekeo, are classified under Japan's Stimulants Control Act, the same law that covers methamphetamine. There is no personal-use exemption, no import permit, no doctor's-letter workaround. Bringing them in is a criminal offense punishable by imprisonment, and a prescription from home is not a defense.
Stimulant raw materials (覚醒剤原料): advance permission required, always
Lisdexamfetamine, meaning Vyvanse, falls here. You may bring a personal supply only after obtaining advance permission from the Narcotics Control Department, supported by a doctor's certificate. It publishes the application forms in English and asks for applications at least 14 days before travel; build in more margin than that, since you cannot travel with the medication until the permission is granted.
Class-1 psychotropics (第一種向精神薬): allowed with quantity limits
Methylphenidate, meaning Concerta and Ritalin, sits here, not in the stimulant categories, and this surprises people in both directions. You may carry a personal supply without any advance permit, as long as the total stays within the official quantity allowance (up to about a month's supply). Carry your prescription; beyond the allowance, the advance import certificate (輸入確認証) is required before travel. Mailing it to Japan is not an option; it travels with you.
Ordinary prescription drugs: the one-month rule
Atomoxetine and guanfacine are none of the above. Like antidepressants, up to one month's personal supply crosses the border with no procedure; larger amounts need the import certificate (輸入確認証) arranged in advance.
Across all boxes: keep everything in original packaging with your prescription label, and never mail controlled ADHD medication to Japan. One of the best-known Adderall arrests in Japan involved exactly that, medication mailed by a family member.
What should you do if you take Adderall?
Talk to your prescriber several months before the move, because the answer is a medication change, and changes take time to settle. The usual candidates: methylphenidate, the closest stimulant relative, available here as Concerta (see our note on the supply situation); or a non-stimulant, atomoxetine or guanfacine. Some people trial the new medication at home before moving, so they arrive on something both legal and known to work.
What does not work: bringing "just a little" Adderall to tide you over. Quantity does not change the classification.
What should you do if you take Vyvanse or Concerta?
Vyvanse: apply as soon as travel dates firm up, and know the adult catch: Vyvanse can't be started in adults in Japan, so the long-term destination will be Concerta or a non-stimulant.
Concerta or Ritalin: no application to make. Use the transition weeks to get assessed and registered in Japan's domestic system; under current supply conditions, start early rather than running your carried supply to the last tablet.
